Bad turbo symptoms? (Professionals recommend)

What are the signs of a blown turbo?

  • The car has noticeable power loss.
  • The acceleration of the car seems slow and noisy.
  • The car doesn’t easily maintain high speeds.
  • There is smoke coming from the exhaust.
  • There is an engine fault light on the dashboard.

What happens when a turbo goes bad?

Be aware that when your turbo fails the pieces will drop down into the intercooler and the oil seals will fail. Unfortunately the engine can actually run on this oil and can run away at maximum RPM until all the oil is used up, at which point the engine will seize.

What does a failing turbo sound like?

Loud noises: If your vehicle has a bad turbo, you may hear loud noises that sound like whining or screeching. So if your vehicle is running and you hear a loud whining sound that increases in volume as the problem goes unfixed, this is most likely to do a turbo problem.

Can you drive with a bad turbo?

You can, but you’ll have to come up with some way to re-plumb everything. I had a 2.3L EFI turbo in a Mustang that blew up on me. It was pouring oil down the exhaust pipe so I couldn’t just drive it with a blown turbo.

Can you drive with blown turbo?

Although you can still drive with a blown turbo, it would be far more preferable to stop driving it and instead bring it to us to have the turbo repaired or replaced. The longer a blown turbo is left without repair, the more damage it will cause to the car’s engine.

How do you diagnose a bad turbo?

What are the signs of a blown turbo?

  1. The car has noticeable power loss.
  2. The acceleration of the car seems slow and noisy.
  3. The car doesn’t easily maintain high speeds.
  4. There is smoke coming from the exhaust.
  5. There is an engine fault light on the dashboard.

How do you tell if a turbo is good or bad?

The symptoms of a damaged or failing turbo are:

  1. Loss of power.
  2. Slower, louder acceleration.
  3. Difficulty maintaining high speeds.
  4. Blue/grey smoke coming from the exhaust.
  5. Engine dashboard light is showing.

Can a turbo engine run without the turbo?

Yes. The engine will still work and you will be able to drive the vehicle but it will be slower than the equivalent vehicle that doesn’t have a turbo. It won’t do any damage to drive a turbo car with no boost. Many cars have a ruptured boost pipe or a burst intercooler which means they have No boost.

What causes turbo failure?

Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.

Can a blocked DPF cause turbo failure?

A blocked DPF prevents exhaust gas passing through the exhaust system at the required rate. Increased exhaust gas temperature and back pressure can affect the turbocharger in a number of ways, including problems with efficiencies, oil leaks, carbonisation of oil within the turbo and exhaust gas leaks from the turbo.

How long will a failing turbo last?

Common reasons why your turbocharger has failed Turbochargers are designed and built to last many years, but like all car components they will eventually fail. You can expect your turbo to last up to around 150,000 miles – or even more if it’s seldom used.

How often do Turbos need to be replaced?

Most turbochargers need to be replaced between 100,000 and 150,000 miles. If you are good at maintaining your car and get timely oil changes your turbocharger may last even longer than that.

How much does it cost to replace turbo?

Turbocharger Assembly Replacement Cost – RepairPal Estimate. Labor costs are estimated between $457 and $576 while parts are priced between $1,368 and $1,530. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

What Causes Turbo Failure & Common Turbo Failure Symptoms

At 9:10 a.m. on July 25, 2019, Turbocharger, commonly referred to as a turbo, is an extra mechanism utilized by automobile manufacturers to increase the power of their engines. In order to give the same amount of power in smaller vehicles as is often seen in bigger vehicles, turbochargers are frequently employed. Almost all automobile manufacturers now offer a turbocharged version of their vehicle in their lineup. In other words, they will be able to deliver smaller engines that provide the same amount of power while simultaneously improving fuel economy.

How Does A Turbo Work?

Fuel and air must be combined in order for an automobile engine to generate the power necessary to move the wheels. Turbochargers increase the amount of air in the mixture by spinning an air pump powered by the exhaust (or compressor). The air pump then forces additional air into the engine’s cylinders, allowing the engine to burn more gasoline per second and create more power than a normally aspirated engine would be capable of. Due to the fact that turbos work at extremely high speeds (up to 250,000rpm), they must function at extremely high pressures and temperatures.

Turbo Failure Symptoms

There are a lot of indicators that your turbocharger has failed that you should be aware of:


The failure of your turbo may be indicated by the fact that your automobile isn’t accelerating as quickly as it once did or is reacting more slowly to your input than it once did. The same is true for a turbocharged vehicle that struggles to maintain high speeds or that is unable to attain speeds it was previously capable of achieving.


The failure of your turbo may be indicated by the fact that your automobile isn’t accelerating as quickly as it once did or is reacting more slowly to your input than it should be. For the same reason, an automobile that struggles to maintain high speeds or that is unable to attain speeds it once could might be suffering from turbo failure.


When oil spills into the exhaust system, it burns off and emits a characteristic blue/grey smoke as it escapes via the exhaust pipe. This might be caused by a crack in the turbo housing or by broken internal seals in the turbocharger unit. If the turbocharger is to blame for this symptom, you’ll be more likely to notice these discolored vapors when the engine rpm climb quickly after starting the engine.


Most current automobiles are equipped with computer diagnostics that can detect turbo failures, and the check engine light will illuminate on the dashboard to alert the driver of the problem. The check engine light, on the other hand, does not always imply turbo failure; you will need to consult with a competent technician to determine the specific nature of the engine problem.

What Causes Turbo Failure?

Turbochargers have a high level of dependability.

Only a small percentage of warranty checks uncover a problem with the turbo itself; instead, blown turbos are typically the consequence of issues with engine lubrication or the entrance of foreign items.


Engine oil is, in a sense, the lifeblood of your automobile. Its primary function is to lubricate and protect critical moving components from corrosion, as well as to keep them cool while in operation. When it comes to the turbocharger, it requires a continuous supply of clean, high-quality oil. An inadequate supply of oil (oil starvation), an inappropriate grade of oil, or low quality oil may result in a buildup of pollutants in the engine’s internal combustion system (oil contamination). This has the potential to inflict abrasive damage to the turbocharger’s inside.


It is possible for oil to seep into an exhaust system if the seals between the compressor and the engine get old or fractured. As a result, the turbo is forced to work harder in order to raise air pressure in the engine. Over-speeding is another term used to describe this issue. In the end, it will lower the efficiency of the turbo and the amount of boost it can deliver.


An engine turbocharger is composed mostly of two primary components: the compressor located at the front and the turbine located at the rear of the engine. Foreign items such as dust particles, dirt, leaves, and tiny stones can occasionally make their way into the turbocharger, either through the compressor intake or the turbine inlet. When a foreign item enters the compressor housing, it is most typically the result of a clogged air filter. If, on the other hand, the foreign item causes harm to the turbine, the problem is almost often caused by the engine itself, as opposed to the other way around.

Your air filter should be maintained and replaced on a regular basis in order to avoid this from happening.


Turbos are intended to last for the life of the vehicle (or around 150,000 miles); nevertheless, depending on how hard you drive the car and the original build quality of the turbo, it is likely that they will wear down over time and require replacement.

Can I Drive With A Blown Turbo?

It is true that you will be able to drive your car if your turbocharger fails; but, engine failure will not be long behind, so only continue driving if you really have to. As soon as you notice any of the turbo failure symptoms listed above, you should get your turbo examined by a trained technician as soon as possible. The longer you put off dealing with the problem, the worse (and more expensive) it will get. At Dowleys Garage, we can perform a diagnostic check to determine the source of the problem and provide recommendations for any necessary repairs.

Signs of a Bad Turbocharger

Adding a turbocharger to your car is one of the most critical upgrades you can make. An exhaust side compressor is a compressor that is mounted on the outside of the vehicle’s exhaust system. Its goal is to increase the horsepower of the engine. As the engine’s revolutions per minute (rpm) grow, the turbocharger forces more air into the engine, boosting its power. A turbocharger has the potential to improve the power of your engine by up to three-quarters. While turbochargers are built to withstand the test of time, they might still have problems after a period of time has passed.

  1. There is an excessive amount of exhaust smoke.
  2. When the leaking oil is burned, it emits a distinctive blue or grey smoke that may be identified.
  3. As a result, if you observe excessive smoke when revving the engine, it is likely that your turbo is malfunctioning.
  4. Another typical indication of a malfunctioning turbocharger is a lack of overall power.
  5. When your car appears to be slow and does not achieve its maximum speeds as fast, it might be an indication that the turbocharger is deteriorating.
  6. The fact that your automobile is consuming more oil than normal might be an indicator that your turbocharger is leaking oil into the exhaust manifold, according to the manufacturer.
  7. Sirens making a lot of noise Turbocharged automobiles are well-known for making nice noises, such as the sound of the blow off valve.

If your automobile is emitting a sound similar to that of a police siren, and the noise is becoming increasingly loud, it might be an indication that your turbo is malfunctioning.

Engine Warning Lights Should Be Checked The majority of today’s automobiles are equipped with computer systems that are capable of detecting turbo issues and turning on the check engine light.

As a result, it is recommended that you do further diagnostic tests to determine exactly what is wrong with your engine.

If you observe a decrease in the amount of boost being produced, this is an indication that the performance of your turbocharger has been compromised.

As a result, you should get your turbocharger inspected by a qualified technician as soon as possible.

If you see any of these signs, don’t hesitate to contact a trustworthy turbocharger specialist such as Taylor Diesel for assistance.

They have decades of combined expertise dealing with a broad variety of turbochargers, including hybrids. In addition to offering economically cost turbocharger diagnostics, Taylor Diesel also provides high-quality turbocharger repairs and replacements.

❤️ SYMPTOMS OF A BAD TURBO ❤️ Everything You Need To Know

The turbocharger, often known as the turbo, in the automobile assists to increase the engine’s output. Because to the introduction of automobile turbochargers, smaller cars are now capable of producing the same amount of power as bigger ones. Automobile repairs are EXTREMELY EXPENSIVE. It is critical to keep an eye out for signs of a failing turbo in order to avoid significant issues, not just with the turbo but also with the entire engine. Early detection of turbo issues can help you save a significant amount of time, effort, and money on automobile repairs.

How does a turbo work?

The turbocharger in the automobile, often known as the turbo, is responsible for assisting the engine in creating additional energy. For the car to move, the engine must burn a mixture of air and gasoline in order to generate enough energy. When there is more fuel in the combustion mixture than there is air, the engine would require more air to interact with the fuel in order to generate combustion and, consequently, energy for the engine. The turbocharger comes in helpful in this situation. The turbocharger in the automobile propels compressed air into the engine, assisting in the combustion of the remaining fuel without the need for a bigger mixing zone.

Turbochargers for automobiles are available in a variety of designs, including:

  • It may be broken down into the following categories: the single turbine
  • The sequential turbine
  • The dual scroll turbo
  • The VGT turbine
  • The variable twin-scroll turbine
  • And the electric turbo.

Symptoms of a bad turbo

Similarly to other mechanical components in your vehicle, the turbo becomes older with time and requires some amount of care in order to avoid significant failures and to maintain your vehicle running optimally. The importance of keeping an eye out for any signs of a faulty turbo cannot be overstated as a car owner. You will be able to remedy the problem sooner rather than later and prevent spending larger repair fees in the future. There are various indications of a faulty turbo, including the following:

Reduction in power

One of the first indicators of turbo failure is a decrease in the power of your vehicle. For example, if you are driving and you realize that your automobile is not accelerating as quickly as it used to, this might be an indication of a failed turbocharger. Furthermore, if you discovered that your automobile was unable to accelerate to greater speeds, despite the fact that you had done everything possible to accelerate, this might be another indicator of turbo failure. Taking your automobile to a skilled technician for diagnosis and repair is essential in this situation to avoid future problems.

Hearing strange noise like engine wining

In general, hearing unusual noises while driving is a symptom of an internal problem with the vehicle. The sort of sound affects whether or not it is the primary source of the difficulty. For example, if you begin to hear a sound similar to an engine winching, such as a police siren or a dental drill, there is a good probability that it is your car’s turbo. Another thing to consider is that if the weird noise becomes louder, the situation is becoming more serious.

That holds true for any and all issues involving private automobiles. In other words, if the sound of the winning engine becomes louder, your turbo problem is becoming more serious and may eventually lead to full turbo failure.

Discolored fumes coming out from the exhaust

As previously stated, the turbocharger is in charge of forcing additional air into the combustion system in order to compensate for any excess fuel in the system. Once an issue with the turbo is identified, such as a little or large fracture, some oil can escape into the combustion system, causing blue smoke to emerge from the exhaust tailpipe. This is because the turbo is overheating. You may check the color of the exhaust smoke to see if any discolored gases are coming out; if so, this indicates that there is a problem with the turbocharger.

Check engine light illuminating

The check engine light on your dashboard is a mechanism for your car’s internal computer to alert you of a problem with the engine or transmission. When the check engine light lights, you should take your automobile to a repair as soon as possible because, while some faults are minor, others are substantially more serious and might result in a full engine failure. When there is an issue with the turbocharger, the check engine light may come on. For the time being, you won’t be able to tell for certain what is causing the check engine light to illuminate until you take your car to a professional technician or have the proper tool to diagnose the problem.

This code may be read with a code reader, which you can purchase, borrow, or request from a mechanic who has one of his or her own.

Using a code reader, you may have a better sense of what to expect from the mechanic in terms of maintenance time and cost before you take your vehicle in.

  • P0299: This code indicates that there is a problem with the turbocharger in your vehicle. More specifically, it is informing the computer in your vehicle that the turbocharger has a low output. Fortunately, if you ignore this code, your automobile will automatically enter “limp mode,” which will prevent additional harm.
  • P0045 OBD-II: This code indicates that there is a problem with the supercharger’s boost control circuit or turbocharger, according to the manufacturer. When this issue occurs, the most noticeable sign is that your vehicle will not function at its peak performance level or at its optimal level, as you will begin to notice a reduction in power.
  • P22262 OBD-II: This code indicates that “Turbo boost pressure not detected-mechanical” has been detected. In other words, the code indicates that your turbocharger has been entirely broken and must be repaired as soon as possible. While your automobile will continue to function despite this problem, the power will be significantly reduced, and you will notice that your car is not operating at its peak
  • Nevertheless, this is temporary.
  • P0234 indicates a “turbocharger overboost condition,” according to the code. In layman’s terms, the code indicates that the turbocharger is supplying more pressure to the combustion system than is necessary by the engine. The quick lack of power, engine overheating, difficulties with the gearbox overheating, and your engine banging when you accelerate are all signs that your vehicle is experiencing this problem.
  • PO299: This code denotes that the status of your vehicle is in an under boost state. In other words, the turbocharger generates a very low output, which is the polar opposite of the preceding fault condition. However, there are a variety of additional factors that might be contributing to this mistake, including an air intake leak, faults with the exhaust gas recirculation system, and the engine not receiving enough oil.

High gas consumption level

As previously stated, the turbocharger is responsible for ensuring that your automobile has the lowest possible fuel usage. The fact that you need to refill your car’s gas tank more frequently than you did previously is a sign of higher gas consumption and, consequently, problems with the vehicle’s turbocharger or exhaust system.

What are the different causes for a bad turbo

In general, problems with the car’s turbo are quite unusual, since they are extremely dependable in their operation. The majority of failures in your automobile’s turbo are caused by problems with other elements of your car, such as engine lubrication, foreign objects, and so on. For example, the following is a list of the most typical reasons for a faulty turbo:

Lack of oil lubrication

Oil is one of the most critical fluids in your automobile, and it must be changed regularly. This is due to the fact that more automotive parts come into contact with one another on a regular basis. The usage of oil offers lubrication, which prevents the parts of the automobile from becoming damaged as a result of friction. The turbocharger in the engine is composed of a number of moving elements that come into contact with one another on a continuous basis and at high speeds. The turbocharger, like every other internal component of a car, requires a set amount of oil to be regularly supplied, as well as a required grade or kind of oil to be supplied in order for it to continue to function effectively.

The oil for the turbocharger is obtained from the engine. When there is insufficient oil in the turbocharger, impurities can accumulate, resulting in oil pollution and, as a result, total failure of the turbocharger.

Issues with the seal between the engine and the compressor

The seals between the engine and the compressor might become worn over time, resulting in internal damage to the engine and compressor. Because of these flaws, oil is able to seep into the combustion system. The turbo needs to work harder and pump more air into the combustion system when there is too much oil in the combustion system, in order to burn the excess oil in the combustion system. It is possible for the turbo to lose efficiency over time if it is forced to work harder than it should.

When a turbo is overspeeding, it is forced to rotate at a faster rate than it was intended to at specified applications.

Strange deposits and objects

Strange things can enter the turbo by one of two routes: either through the compressor hose in the front or through the turbine in the back. Strange things entering the turbo from any source or position can do significant damage to the turbo and the entire engine, regardless of where they came from or where they went. Once unusual items begin to accumulate inside the turbo, you will begin to notice a reduction in the car’s power, if not a complete failure of the turbo system. The most effective method of preventing this problem from occurring is to undertake frequent cleaning up to the air inside of the turbocharger.

Tear and wear over time of use

As previously said, turbochargers are quite dependable and do not sustain damage very frequently. In average, turbochargers have a service life of up to 150,000 miles before they need to be replaced. This figure, on the other hand, may vary based on your driving technique. For example, if you drive your automobile excessively aggressively, you should assume that your car’s turbo will be broken sooner rather than later.

Can I still drive my car if there are symptoms of bad turbo

Even if you are experiencing signs of a malfunctioning turbo, you should not drive your car; nonetheless, the longer you wait to address the problem, the greater the likelihood that your engine may fail very soon. As a result, you should only drive your automobile when absolutely necessary, and you should take your vehicle to the nearest technician as soon as possible. For some people, taking their automobile to a mechanic shop to have their turbo fixed is not an option since they do not have the time.


Turbochargers in automobiles enabled people to drive smaller vehicles with the same amount of power as larger vehicles. The turbocharger in your automobile improves the performance of your engine while also increasing the efficiency of your fuel consumption. In general, automobile turbos are quite reliable and do not fail until they have traveled around 150,000 miles, depending on your driving style. Although it is unlikely, there will come a time when you will need to conduct some maintenance on your car’s turbo in order to extend the life of your car’s engine and, consequently, the life of your whole vehicle.

The majority of issues with the car’s turbo are caused by other factors such as a lack of engine lubrication and the introduction of foreign items into the vehicle.

Immediately take your car to a local technician if you see any of the indications of a faulty turbo. Failure to do so may result in further issues that will cost you more time, effort, and money in the long run.

Common Turbo Faults and How to Spot Them

Since 1974, our highly skilled technicians have been assisting clients from all across the United Kingdom with their turbocharger repairs. In this post, we’ll share some of our expertise on typical causes of turbocharger damage, as well as show you how to detect whether your turbocharger is in need of servicing, repair, or rebuild. If you have any questions, please contact us.

The cause of damage

There are multiple major reasons of turbocharger damage, the most significant of which are as follows:


Turbines require a continuous supply of clean oil in order to function properly, and in order to keep your turbo in peak operating condition, you must ensure that the oil and oil filter are changed on a regular basis. This helps to avoid the build-up of carbon deposits and pollutants that may cause abrasive damage to the interior of your turbocharger, limiting its performance and inflicting irreversible damage over time, as well as the accumulation of carbon deposits and contaminants. The least quantity of carbon dioxide is produced by fully synthetic oil.

Foreign objects

Foreign items such as damaged engine components, dust particles, tiny stones, dirt, and leaves can sometimes find their way into your turbocharger, either through the compressor intake or the turbine inlet, and cause damage. Impact damage and abrasion to the compressor wheels and turbine blades might result as a result of this, which will begin to degrade the effectiveness of the turbocharger. In order to avoid this from occurring, you must ensure that your air filter is maintained on a regular basis and that you inspect your turbo for loose connections or foreign objects.


Increasing the amount of air pressure in an engine is how a turbocharger works (check out ourbeginners FAQfor further info). Because of leaks, cracks, or inadequate seals between the compressor and the engine, the turbo will have to work considerably harder than it should to achieve the desired rise in pressurization. The efficiency and boost generated by the turbo will be reduced as a result of this.

Other causes

Besides the factors outlined above, other factors such as high exhaust gas temperatures (EGTs), moisture ingress, wear and tear, fuel intake systems, the wastegate, and the exhaust system can all contribute to the failure of your turbocharger.

The warning signs

Several indicators will indicate to you that your vehicle’s turbo is in need of maintenance or repair, including: Engine warning lights should be checked– Turbo issues are detected by computer diagnostics in the majority of modern automobiles, resulting in the check engine light being illuminated. Of course, the check engine light does not illuminate only in the case of a turbo failure, and you will need to do other tests to determine what type of engine problem you are dealing with. The boost gauge- Some turbocharged cars are equipped with a boost gauge, which indicates how much boost is being produced by the turbocharger (you can also fit one to your car if desired).

Increased power loss– If you find that your turbocharged car is accelerating more slowly than normal, or that it isn’t capable of reaching the speeds it used to be capable of, this might be a clue that your turbo is malfunctioning.

After burning off, it leaves an unmistakable blue/grey smoke trailing behind the vehicle, which will become more noticeable when the engine rpm increase immediately following an idle condition.

You should get your engine examined if you start to hear this type of noise coming from your engine.

The next steps – checking your turbo

If you see any of the danger signals, you should get your turbo examined as soon as you possibly can. If you ignore the problem, it will only grow worse (and more expensive) as time goes on. Don’t put off fixing your turbocharger any longer! We at AET are always delighted to assist with the cost-effective diagnosis and repair of a wide range of turbochargers. Please contact us now for more information. Alternatively, if you’re mechanically inclined and don’t mind getting your hands dirty under the hood, you may inspect the turbo yourself and check for a variety of issues.

  1. Before you begin, we recommend that you verify that your vehicle’s air filter, exhaust system, breather system, and fuel system are all in correct operating order, since these systems might exhibit symptoms that are similar to turbo failure.
  2. First, inspect the outside of the vehicle, looking for evidence of grease or loosened connections.
  3. Keep an eye out for signs of excessive movement, and make sure that the wheel does not come into contact with the housing.
  4. It’s also possible to inspect the turbo’s exhaust side if you’re feeling very daring and ambitious.
  5. Cleanness is essential; there should be no carbon build-up, scale, or grease along the surface of the blades, and there should be no fractures, wear, or damage to the blades.
  6. Take a look at our frequently updated gallery of failures for some common instances of broken turbochargers as well as information on what to look for.

Worried about a blown turbo? Know all about Turbo Repair

The turbocharger is intended to last as long as your automobile. However, the turbo can become damaged with time, which is why you should be well-versed in the subject of Minnesota Turbo Repair. During this blog post, we’ll go over the telltale indicators of a blown turbo, the most prevalent causes of turbo failure, and what to do if your turbocharger fails.

As well as Turbocharger Replacement, Garret Turbochargers, and why Diesel Components, Inc. should be your first choice for everything relating to Turbo Repair or Replacement, we’ll cover the following topics:

What are the signs of a blown turbo?

  • The car’s age and mileage are important considerations. There is not enough engine oil in the system. The wrong type of oil was used
  • Seals that have been damaged (this permits oil to enter the exhaust system)

If your turbo fails for whatever reason, there are a variety of symptoms that might occur. The tell-tale signs of the most prevalent turbo issues may be identified if you constantly monitor the way your automobile performs, which is something you should do. As a result, you can confirm the possibility of turbo difficulties, but you will require our services to conduct a diagnostic test in order to determine the source of the problem. In addition, when you come to see us, we may discuss turbo rebuilding with you.

The most common signs of a blown turbo are:

  • Your vehicle is experiencing a notable decrease of power
  • Your car’s acceleration appears to be sluggish and loud
  • Nevertheless, this is not the case. Your vehicle has difficulty maintaining high speeds
  • There’s a cloud of smoke billowing out of the exhaust
  • On the dashboard, there is an engine problem light illuminated.

Common reasons why your turbo has failed:

There are a variety of reasons why turbochargers malfunction. The following are the most often encountered:

Carbon/particle deposits

When you don’t replace your oil on a regular basis, carbon deposits begin to accumulate. Make certain that the company replaces your oil every time you bring your vehicle in for repair. The addition of a turbocharger provides several advantages to the general health of your car. Even the presence of very modest quantities of pollutants in it can result in costly and troublesome mechanical problems.


Turbos are intended and manufactured to survive for many years, but they will ultimately fail, just like the rest of your car’s components. If you don’t use your turbo much, you may anticipate it to last roughly 150,000 miles or even longer if you maintain it properly.

Cracked/damaged seals

Turbochargers inject extra air into your car’s cylinders, increasing the amount of pressure in the engine. If the essential pressure in your turbo is reduced as a result of cracks in the turbo, your turbo will have to work harder to give the appropriate turbo boost, finally leading it to fail.

What should I do if my turbocharger fails?

Turbochargers inject extra air into your car’s cylinders, increasing the amount of air pressure in the engine compartment. The turbo will have to work harder to generate the requisite turbo boost if this necessary pressure is reduced as a result of cracks in the turbo. This will finally result in the turbo failing.

Below are some things that our expert team at Diesel Components, Inc. will inspect if your turbocharger fails

This list is not exhaustive because some engines have additional components that must be checked as well. Continue reading to learn about some of the things we’ll be doing when fixing your turbo:

  1. We will take some time to evaluate the air intake and exhaust systems to verify that they are in good working order and clear of pollutants before continuing. The exhaust or intake system of your vehicle might become clogged with components of your failed turbo if your turbo fails catastrophically. They may return after the new turbo is installed, resulting in damage to the new turbo
  2. We will change the oil and filters to prevent this from happening. This would be done after removing the sump to ensure that all of the material that was causing the turbocharger failure has been removed. After that, we’ll remove the oil feed pipe and fittings and examine them for any contamination. You can also request that we change the air filter if you so want. Our technicians will check the intercooler since there may still be small amounts of oil or pieces from the original failed turbo lurking within it. When a catalytic converter or diesel particulate filter (DPF) is present in the exhaust system, we shall clean or replace them to guarantee proper performance. We will inspect the intake pipes for fractures and corrosion. Finally, we will look for any signs of exhaust leakage. Is it possible to drive with a blown turbo?

The longer you keep your automobile on the road with a damaged turbo, the more harm it will do to the engine. This will also increase the expense of your turbocharger repair above and above what it should be. Despite the fact that you may still drive with a blown turbo, it is far advisable to stop driving and instead bring your vehicle to us so that we can repair or replace the turbo. The longer a blown turbo is allowed to go without being repaired, the more harm it will do to the car’s engine and transmission.

Bad Turbo Symptoms, Problems and Repairs

Known as a turbocharger or turbo, a turbocharger is an extra device used by automobile manufacturers to enhance engine power. It is capable of delivering the same amount of power in smaller vehicles that is often seen in bigger vehicles. A faulty turbo will reduce the power of your vehicle, necessitating the necessity for prompt repairs. Let’s look at the signs and symptoms of a faulty turbo and how to fix them.

How Does A Turbo Work?

In order to fully comprehend the indicators of a faulty turbo, we must first grasp how a turbo works. The turbocharger on a car works on a basis that is quite similar to that of a piston engine. The exhaust gas is used to power a turbine, which is located on the roof. This turns a compressor, which pushes more air (and oxygen) into the cylinders, allowing them to burn more fuel per second as a result of the rotation. It’s for this reason that a turbocharged car may create more power than a bigger one.

In practice, a turbocharger is made up of two small air fans that are mounted on the same metal shaft and rotate in tandem with one another.

Whenever the cylinders blow hot gas past the fan blades, the fan blades themselves revolve, and the shaft to which they are linked also turns.

Due to the fact that it is positioned within the car’s air intake, when the engine starts, it sucks air into the vehicle and forces it into the cylinders.

In both theory and reality, this is how the turbocharger operates. Let us move on to the symptoms of a faulty turbo now that you are familiar with its operation and principles.

How To Tell If Turbo Is Bad?

As a result, as the turbo’s major role, it contributes to making the smaller automobile have more power comparable to the larger car, i.e., more powerful than the larger car. One of the first obvious signs is a loss of power and a sluggish response while starting the vehicle. If you find that your vehicle isn’t accelerating as quickly as it used to, the first thing you should consider inspecting is the turbocharger. The same is true for a turbocharged vehicle that struggles to maintain high speeds or that is unable to attain speeds it was previously capable of achieving.

The first visible signs are a loss of power and a sluggish response while starting the vehicle.

2. Whining Engine

Because it muffles the sound of the engine’s air intake, the turbo actually makes the engine quieter than it would otherwise be. Then, if you notice a noise coming from the engine that is louder than usual, such as a dentist’s drill or a police siren, there is a 100 percent possibility that you have blown turbo symptoms. If you ignore the blown turbo sound, the noise will get more louder and the condition of your automobile will deteriorate. Whenever you hear a whine coming from your engine, you should take your vehicle to a competent technician for an inspection.

3. Burning Engine Oil

One of the negative turbo symptoms is that the automobile consumes an excessive quantity of oil compared to normal. An endoscope may be used to see into the turbine; if there is oil within, this indicates that the turbine is experiencing indications of failure. Since your turbo will ultimately fail if the problem is not addressed immediately, you should rectify the issue as quickly as possible.

4. Excessive Exhaust Smoke

If you notice blue or grey smoke coming from your automobile while driving, the likelihood that your vehicle has a malfunctioning turbo is quite high. So, what’s the deal with grey smoke? When there is a break in the turbo housing or broken internal seals, this might cause an oil leak in the exhaust system, which results in the production of grey or blue exhaust air. Aside from that, you may notice the discolored vapors as the engine rpm increase immediately after it has been idled for a while.

5. Check The Engine Light

A failed turbo will be detected by the computer diagnostics system in most current automobiles, resulting in the “check your engine” message. When this happens, the automobile is attempting to communicate with you that something awful has happened to your turbo. In this scenario, you may want the assistance of a specialist who can assist you in determining the actual nature of the automobile problem. Making an appointment with a technician is an excellent solution in this situation. MORE INFORMATION CAN BE FOUND AT:

6. The Boost Gauge

In some automobile models, it is customary to be able to view the boost gauge; thus, if your car is equipped with a boost gauge, even if it is an aftermarket one, it is an amazing method to determine how effectively our turbo is doing. Using this method, even if you are unable to observe the bad turbo symptoms clearly, you may still detect the problem with your automobile. If you observe a decrease in the amount of boost being produced, this is a symptom that the performance of your turbocharger has been compromised.

A drop might be caused by a number of different turbo issues. As a result, you should get your turbocharger inspected by a qualified technician as soon as possible.

What Causes A Blown Turbo?

There are a variety of factors that contribute to the unpleasant turbo symptoms. Turbos that have blown up are typically the consequence of issues with engine lubrication or the entry of extraneous items into the engine.

1. Age or Normal Wear and Tear

Everything, like the majority of automobile components, has a useful life expectancy. A turbocharger may normally last between 100,000 and 150,000 miles before needing to be replaced. According to the driver and their driving habits, this figure might vary significantly. However, depending on how hard you drive the car and the quality of the turbo’s initial construction, it is possible for them to wear out over a period of time.

2. Oil

Engine oil, which is similar to blood in the human body, is primarily present in the automobile to ensure that the turbocharger operates properly. Its primary function is to lubricate and protect critical moving components from corrosion, as well as to keep them cool while in operation. Because of this, it requires a continuous supply of clean, high-quality oil. The use of low-quality or incorrect-grade oil will result in a buildup of impurities in the engine’s internal combustion engine. This has the potential to inflict abrasive damage to the turbocharger’s inside.

The use of low-quality or incorrect-grade oil will result in a buildup of impurities in the engine’s internal combustion engine.

3. Foreign Objects/Deposits

The turbo is composed of two main components: the compressor, which is located at the front, and the turbine, which is located at the rear. The turbocharger can become clogged with foreign items such as dust or dirt, leaves, or other tiny debris that might create issues. If these foreign things enter the air filter, the effectiveness of the turbo will be lowered as a result of this. Your air filter should be maintained and replaced on a regular basis in order to avoid this from happening. Additionally, you should inspect your turbo for debris.

4. Bad Seal

The seal that links the compressor to the engine is a very critical component. It is possible that the oil will leak into the exhaust system if it begins to wear out or fracture. Consequently, the turbo has to work harder and is more likely to be blown. The efficiency of the turbo will decrease as a result, resulting in severe turbo symptoms. So, as soon as possible, take your automobile to a professional who will analyze exactly what is wrong with your car’s turbo and then fix it immediately.

Can You Drive With A Blown Turbo?

If the turbocharger fails, you will still be able to drive your automobile, but the engine failure will not be far behind in its progression. As a result, you should only continue driving if absolutely necessary.

We strongly advise you to take your automobile to a reputable technician as soon as possible after purchasing it. If there is an issue, it must be addressed immediately since the longer it is ignored, the worse and more expensive the problem will become.

What To Do If You Have A Blown Turbo

If you suspect that your turbo is blown, you should get it locked as soon as possible by a trained mechanic. The cost of repairing a turbo will vary depending on the make and model of your car, as is the case with most other auto components and services. It’s important to note that estimating turbo repair prices might be challenging owing to the wide variety of components and labor estimates available. We propose that you contact directly with your technician and obtain an estimate before allowing him to perform any repair on your vehicle rather than leaving it in that state of affairs.



An overheated turbo can be caused by a variety of factors, and it can manifest itself in a variety of ways, including exhaust smoke, gray smoke, engine noise, boost gauge, burnt oil, and other symptoms. Make a habit of taking your automobile to the garage for repair on a regular basis. Furthermore, it is recommended that you get your oil changed after each service to avoid carbon buildup. In the event that the turbo is beyond repair, replacing it with a new one is a wise option. If you are unsure about the operation of your car’s engine, a professional mechanic can assist you.

6 Signs Your Car has a Failing Turbocharger

Your turbocharger is a crucial component of your engine, allowing you to accelerate more quickly and reach top speeds in critical situations. It provides the necessary acceleration when you need to overtake on the highway fast and safely. It is possible to hear a gratifying rush as the turbocharger kicks in, driving air into the engine, on some vehicles. Alternatively, if your turbo fails to function properly, your engine may become inefficient and suffer from low performance. What are some of the telltale indicators that your turbo is on its way out?

The turbocharger forces more air into the engine, thereby increasing the amount of energy available for combustion and improving the peak levels of performance.

This air pump then forces the increased air into your engine, resulting in an increase in horse power.

What causes a turbo to break down?

Turbo failure can be caused by a variety of factors, the most prevalent of which are as follows: Lack of oil and lubrication– In order for the turbo to function effectively, it requires a continuous supply of clean oil. It is susceptible to the accumulation of carbon deposits and pollutants, which can limit its efficacy and even lead it to entirely fail over time. It is possible that bigger pieces of debris, such as stones or even broken automobile components from other vehicles, will be drawn into the turbo through the input valve.

  • Check to see that your air filter is being maintained on a regular basis.
  • Over time, this pressure can develop leaks and cracks, increasing the amount of work the turbo has to do and increasing the amount of tiredness the driver feels.
  • Age and wear and tear– as you might think, a turbocharger is not going to survive indefinitely.
  • It will need to be replaced at some point.

Overheating caused by excessive exhaust gas temperature (EGT) and moisture infiltration might result in corrosion and damage of the component. In addition, faults with the exhaust system, the fuel intake system, and the waste gate might cause the turbo to fail prematurely.

Signs of a Failed Turbo

Keep an eye out for the following signs of a failing turbo in your automobile to help you detect the problem: There will be a loss of power and a delayed acceleration because the turbocharger is meant to help your automobile achieve peak speeds more quickly. You will, of course, become acutely aware of its powers and performance as time goes on. If you find that your car is taking longer to get up to speed and that it is no longer able to waltz between the lanes of traffic as it once did, the turbo should be the first thing you look into.

  • This causes oil to enter the exhaust and burn out as a distinctive greyish blue smoke when the turbocharger is turned on.
  • It is possible for the check engine light to appear on your dashboard for a number of different reasons.
  • Preventative maintenance includes having your automobile inspected by an auto professional.
  • You’ll gain a better sense of the performance with time, much like you did with your acceleration.
  • Oil that is burning– as previously said, oil seeping from the turbocharger is an indication of eventual failure.
  • Is there any oil visible?
  • If this problem is not addressed immediately, the entire system may fail.
  • If this indicator is present in conjunction with any of the other signs listed below, you may be certain that there are problems with the part.

Can you still drive with a blown turbo?

If you suspect that your turbo is blown, it is a good idea to pull over and inspect it for damage before continuing. Even if the presence of smoke coming from the component is quite indisputable, if you’re still not convinced, remove the intake and examine the shaft. Even while you can get away with driving without the turbo, it is generally safer to ask for a recovery lift if the problem is severe. If you opt to drive with a broken turbo, you must first disconnect the connection from the wastegate activator and then use a wire to keep the wastegate open while you drive the necessary distance to a repair.

Take it easy on the throttle, since the wastegate won’t be able to bear the full force of the exhaust if you push it too hard. If you opt to drive with a blown turbo, make sure to keep an eye on your oil level and limit your driving distance to no more than 100 miles.

And finally

You should be aware that if your turbo fails, the parts will fall into the intercooler and the oil seals will fail as a result. Unfortunately, the engine can really operate on this oil and will continue to run at its maximum RPM until the oil is completely depleted, at which time the engine will seize completely. To prevent inflicting significant damage to your engine if your turbo fails, remove the intercooler, air box, and all of the tubing from the engine. If you’re fast to react, you may be able to replace your turbo yourself, saving both time and money on a costly garage repair.

Turbocharger troubleshooting

Sometime a truck will come into the shop with its owner saying that there is a problem with the turbocharger. While this may be true, it is also conceivable that the turbo was a victim of circumstance, and that there are alternate explanations for why the turbo has failed. For more than a decade, says John Ferry, executive vice president of TurboSolutions, turbochargers have been a popular topic in repair shops. He believes the industry is still in the process of becoming more knowledgeable about turbochargers.

  1. Simple turbos were replaced with more complicated variable geometry turbos (VGT), which cost six times as much as their predecessors.
  2. Service providers that are fast to switch out a turbocharger without thoroughly evaluating the rest of the system stand a strong possibility of seeing a dissatisfied client in a few months who is complaining about the same problem they had initially.
  3. As a result, when something goes wrong, it usually goes wrong quickly.
  4. In order to fully comprehend a turbo failure, it is necessary to identify and eliminate its fundamental cause.
  5. If an engine has an electrical turbocharger, the technicians should check the electrical connections for damage as well as all pipework and clamps as well as oil and water lines.
  6. One of the most prevalent issues is that turbochargers are returned even if there is nothing wrong with them.
  7. “It’s referred to as misdiagnosis,” Ferry explains.

They take their chances and ship it back to the manufacturer for warranty coverage.

A handful of warning indicators (see chart from Turbo Solutions) are most frequently seen by technicians while diagnosing suspected turbocharger faults, according to industry experts.

BorgWarner is the source of this information.

“The fact is that it may not be the turbocharger at all; it may be a shortage of air and as assimple as an air cleaner, but they will almost certainly blame the turbocharger,” Golema explains.

“Excessive exhaust limitation might result in a loss of power,” he continues.

In the case of an out-of-balance turbo, it will generate a different sound; if the turbo has been damaged and a blade has been chipped, the pitch that the turbo is designed to produce will be altered, explains Temple.

He recommends that you check for an obstruction in the turbocharger’s oil supply.

“Noticing unusual pitch is one technique to identify a problem, but you must first discover the unusual pitch.

Additionally, the color and position of the smoke can provide indications as to what could be creating troubles with the turbocharger or another element of the truck.

There are two possible reasons for this: either the fuel condition is excessively rich or the turbocharger is ineffective.

“You have to figure out why it isn’t getting any air flow.

If the turbo is operational, but it is unable to provide air to the turbo due to a blocked air filter, is this a cause for concern?” Temple expresses himself.

Other possible causes of blue smoke include a blocked, leaky, or distorted crankcase ventilation system, coke and sludge in the turbocharger center housing, and a filthy air filter system, among other things.

Experts believe that turbochargers are particularly vulnerable to soot and foreign object impact damage (FOID).

Back pressure is formed and soot accumulates inside the turbocharger if the diesel particulate filter — and the aftertreatment system as a whole — is not properly functioning or maintained, for example.

“If you have a badvalve that becomes completely carbonized, little particles of carbon can break off and go into the turbocharger,” says the author.

“Aftertreatment is meant to function in conjunction with the turbo,” Temple continues.

If anything, it puts additional strain on the turbo, yet it is necessary for the system to function properly.” The turbocharger is being inspected The interior of the turbocharger can disclose damage as well as information as to what could be causing it because turbochargers are meant to last the whole life of the engine.

  1. The operator will be informed if there is a problem with the actuator by a code shown on the instrument panel, however this may not be the case.
  2. Taking the actuator out of the equation allows technicians to inspect the VGTlever, which travels up and down.
  3. According to him, if the lever can be moved freely, the turbo is in good working order.
  4. He also recommends that the rotor system be moved manually in both the axial and radial directions.
  5. Because of overspeeding or a large amount of contaminated oil passing through the turbo, the bearings will begin to wear down, and the customary clearances for end (or axial)play and radial play will allow the turbo to operate outside of its specified limits, according to Temple Engineering.
  6. BorgWarner Checking the turbocharger and turbine for debris, grease, or sludge in the housing might cause the turbocharger to get clogged.
  7. TurbochargerTLC specialists agree that lubrication, filters, and periodic maintenance are the most critical aspects of keeping a turbocharger healthy and working as it should.
  8. “If that supply line is not delivering enough oil to the turbo, you run the danger of the turbo burning up in three seconds,” he continues.
  9. It is possible that components in the engine aftertreatment system might shorten the turbo’s life if you do not follow these instructions.
  10. “Use the factory-recommendedOEM oil that is approved for your vehicle.

He advises to “do those two things and you’ll be relatively safe when it comes to the engine and turbocharger.” Ventress also points out that the turbocharger is affected by crankcase ventilation, thus maintaining the crankcase ventilation system — filters and pipes — clean and clear can substantially improve the turbocharger’s capacity to seal oil in the turbo bearing housing, according to the manufacturer.

High crankcase pressure as a result of inadequate ventilation is a typical cause of oil leaks from the turbocharger.

In the words of Headds, “Maintaining the engine properly will protect the turbocharger, and it is extremely crucial that end users adhere to the engine OEMservice intervals and utilize authentic components wherever feasible.”
