Subaru turbo failure? (Perfect answer)

Misfires. Misfiring is also one of the Subaru turbo problems. This issue can be caused by vacuum or boost leaks, faulty ringland on the pistons, or tight exhaust valve clearances.

What are the signs of turbo failure?

The symptoms of a damaged or failing turbo are:

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

What happens when a turbo fails?

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.

Why did Subaru stop making turbos?

In a recent interview with Motor Trend, Subaru of America President and CEO Tom Doll told them Subaru won’t be bringing a Forester with a turbocharged engine anytime soon. Doll says it’s because demand for the newly-redesigned Forester SUV is too high right out of the gate.

Are Subaru turbocharged engines reliable?

Yes. Subaru turbo engines are very reliable. I’ve driven one for the past 6 1/2 years and about 50,000 miles with no problems.

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.

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 a turbo be repaired?

Yes! In the right hands, almost all problems of turbochargers can be repaired. What is more important is to identify the problem with the turbocharger and how to repair it. To understand how to diagnose turbocharger repairs, here are a couple of significant repair tips to remember.

Why would my turbo stop working?

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.

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.

Is the Subaru 2.5 Turbo a good engine?

EJ255 Subaru engines are 2.5L turbo flat four engines found in several 2004-2014 US models. The engine is still in use in other parts of the world, as of 2020. It’s a strong engine from the factory producing 210-265 horsepower. The EJ255 really is a solid overall engine.

Why are there no more forester turbos?

Subaru did comment and stated that they discontinued the 2.0XT Forester because it had sportiness already and did not equate to more power for the new-generation model. The XT version of the Subaru vehicle models are designed for more power and added traction to allow tight cornering with the all-wheel drive model.

How long do Subaru 2.5 engines last?

Generally speaking, a Subaru 2.5 engine has the ability to run between 250,000 and 300,000 miles before needing any kind of significant auto maintenance or repair. Since most drivers average around 14,000 miles per year, this would mean that a Subaru 2.5 engine could conceivably run for over two decades.

Is the 2.4 L boxer engine reliable?

The 2.0-liter flat-four was a good engine, but here’s why the FA24 (the engine code that Subaru uses to identify the new engine) 2.4-liter Boxer is the best turbocharged engine yet. Buyers who don’t modify their engines will have enough power, torque, and a reliable engine with improved fuel mileage.

What is the most reliable Subaru engine?

The Subaru 2.5L engine can be very reliable and is very capable of outlasting the vast majority of engines with 200,000–300,000 miles being common and even higher possible.

Subaru Turbo Problems ❤️ Everything You Need to Know!

Turbo engines are becoming increasingly prevalent in today’s world. Turbo engines were formerly reserved for high-performance vehicles with extreme acceleration, but they are now found in the majority of modern automobiles on the market today – Subaru being one of them. There are several Subaru automobiles available that are fitted with turbocharged engines. However, while turbo engines are designed to be durable and dependable, they are not without their flaws. Several Subaru drivers have expressed concern about turbo difficulties with their vehicles in the past.

The Cost of Auto Repairs Is ExorbitantSubaru turbo engines have gone a long way since they were first introduced, and there have been indications that its turbo engines are becoming increasingly reliable and capable of delivering increased performance.

What can you do to make things better?

Subaru Turbo Problems: Do Subarus have engine problems?

However, despite the fact that Subaru turbo engines are engineered to be durable and reliable, they are still susceptible to various Subaru turbo difficulties. Subarus are known to experience engine troubles. Yes, they have, and now we will talk about the most typical Subaru turbo problems you may encounter. The following are some of the most prevalent Subaru turbo issues. According to certain accounts, certain Subaru turbo faults might result in oil starvation if not addressed immediately. This is reported to be due to the oil filter being utilized by Subaru, which is the source of the problem.

There will come a time where the filter becomes clogged with matter and will be forced to operate in bypass mode.
It has a union screw or bolt that is a filter that is inserted in the turbo’s oil supply line, and it is found on the Subaru.
Every 60,000 miles or more depending on how the vehicle is operated, the oil supply bolts should be examined and changed if necessary to avoid this problem.
Because of the failure to perform adequate oil change maintenance, sludge and deposits created by oil degradation may clog the oil passageways, potentially resulting in excessive wear owing to a lack of lubrication and causing excessive wear.
Several factors can contribute to this problem, including vacuum or boost leaks, worn or damaged ringland on the pistons, and restricted exhaust valve clearances.

Because of the heat cycles that occur, a tight valve clearance might develop over time. After experiencing this problem, it is critical that you have your vehicle evaluated as soon possible since neglecting the problem might result in a much worse problem that may be too expensive to repair.

According to reports, this problem is widespread on Subaru EJ255 turbo engines. The Subaru EJ255 is powered by a 2.5-liter flat-four engine with a manual transmission. There are three piston rings in this engine. Ringlands — the regions between the three piston rings – are susceptible to cracking and are frequently the starting point for piston troubles. The presence of a slight fracture will not pose an issue, and you will not be aware of it unless the engine is dismantled. If the cracks remain minor, they will not pose an issue; but, if they begin to grow in size, you will lose a section of the piston, ring, or ringlands as a result.

You might wind up losing part, if not all, of the compression in the damaged cylinder, and you could even cause damage to the cylinder walls as a result of this.
The knocking sound that comes from the engine might be generated by a portion of the piston being lost in the process of combustion.
Because the piston will not be able to completely seal the combustion chamber, you will experience a loss of cylinder compression, which may result in a loss of power.
When you are experiencing this problem, it is advisable to get your vehicle inspected so that a precise diagnosis can be made.
You can solve the problem by rebuilding the engine with a new piston, but the cylinder walls will need to be machined in order to accomplish this.
In a complaint filed against Subaru on November 15, 2018, the company claimed that the ringland failure was the result of piston detonation, which may cause unexpected engine breakdowns.
In most cases, the rod bearings are the first to be damaged when there is an issue with oil flow.
When the rod bearings fail, the rods might slap against the cylinder walls, causing the cylinder to overheat.
Rod knocks, which tend to sound terrible and rise in volume as the RPM increases, are one of the symptoms of a failing rod bearing.
You should either check your oil for metal particles or get it tested for metal shavings.

If you see any of the early indicators of a deteriorating rod bearing, do not dismiss the situation. It’s important to get your automobile evaluated as soon as possible so that you can remedy the problem before it becomes too serious.

Gaskets are known to be subjected to a great deal of wear and tear over time. Valve cover gaskets, also known as VCGs, are known to degrade over time and will begin to leak oil as the vehicle ages and accumulates miles and age. If your Subaru turbo car is more than ten years old or has more than 100,000 miles on it, it is possible that it will begin to leak at any time. Perhaps you should get it changed in order to avoid more difficulties. A failing valve cover gasket is characterized by the presence of smoke emanating from the engine bay.

The smell of burning oil might also suggest the presence of the same issue.

Subaru Turbo Problems:Is the Subaru turbo engine reliable?

Subaru is well-known for producing vehicles that are both highly competent and dependable. Despite the fact that they have been in the automobile manufacturing industry since 1954, they just joined the American market in 1968. Since its inception, this Japanese automobile manufacturer has gone a long way. Subaru, in fact, gained the 8th position out of 26 vehicle manufacturers in the United States automotive industry, making them one of the most dependable automobile brands on the market today.

The BRZ was first unveiled in 2012.
Subaru also offers turbocharged variants of its passenger vehicles, such as the Legacy XT, WRX, and Outback XT, among other models.
Despite the fact that there have been reports of Subaru turbo difficulties with these turbocharged versions of the cars, these engines were nonetheless well-known for their performance, for reacting well to tune and modifications, and for being a reliable overall engine.
Turbocharged boxer engines are also being produced, which can deliver a more powerful performance than the standard engines.
The Subaru WRX is equipped with this turbocharged engine.
The new Subaru Legacy, Ascent, and Outback cars are powered by a 2.04L turbo 4-cylinder engine with direct injection.
The Subaru Legacy’s turbocharged engine is also fuel-efficient, achieving 32 miles per gallon on the motorway and providing a total driving range of over 600 miles on the interstate.

The Subaru Outback and the Subaru Ascent both achieve 27 miles per gallon on the interstate. With a towing capability of 5,000 pounds, the Subaru Ascent is a strong vehicle, and the turbocharged Subaru Outback has a towing capacity of 2,500 pounds.

This is the most powerful turbocharged boxer engine currently on the market, according to the manufacturer. The Subaru WRX STI is powered by this engine. It is capable of delivering both tremendous performance and exceptional handling. It is capable of producing 310 horsepower and 290 pound-feet of torque. Powered by a 2.5-liter turbocharged engine, the vehicle can go from zero to sixty in 4.9 seconds. Subaru turbo engines are becoming more powerful than ever, and the company has learnt from the mistakes of the past with Subaru turbo engines.

Many people still have Subarus with turbo engines that have more than 150,000 miles on them and are still operating.

Subaru Turbo Problems:Which Subaru engines to avoid?

Subaru turbo engine troubles and which engines to avoid are important to be aware of when shopping for a secondhand Subaru car with a turbo engine. Subaru is well-known for having a tiny yet committed following of customers. They are extremely devoted to Subaru, which is why the company specifically targets people who appreciate and are faithful to its characteristic engines, drivetrains, and cars with off-road capability, among other things. However, there are some Subaru turbo problems that you cannot just dodge or pretend don’t exist, such as the one described above.

The high-performance 2.5L turbocharged engines used in the Subaru Impreza WRX and WRX STI models from 2009 to 2014 are the Subaru turbo engines that you should avoid using in your vehicle.
Replacement of an engine might cost anything from $8,000 to $12,000.
Because of the casting method Subaru employed, the piston ringlands became weak, and the crankcase ventilation system allowed crankcase oil vapors to enter the combustion chamber.
The plaintiffs allege that their vehicles suffer from abrupt power loss or engine failure as a result of the defect.

Subaru Turbo Problems: Final Word

There are certain Subaru turbo problems that are serious on particular models, but there are also numerous Subaru vehicles that have just minor faults with their turbos.

If you are in the market for a used Subaru, make sure to do your homework and stay away from turbo engines, which are known to be the source of many Subaru turbo issues.

2002-2008 Subaru Turbocharger Failure – Buy Auto Parts

Many Japanese automobiles are renowned for their dependability. Subaru, in fact, has earned one of the most well-deserved reputations among automakers for designing and manufacturing vehicles with durable drivetrains, powerful engines, and well-handling chassis. However, this does not imply that every Subaru that leaves the factory is flawlessly engineered and manufactured. Specifically, we’ll be talking about one such issue that we’ve begun to see with increasing regularity in recent months.

By pairing the turbocharged boxer engine with Subaru’s full-time all-wheel drive technology, the turbocharged boxer engine became the core of one of the most popular and reasonably priced compact automobiles on the market.
Unfortunately, the majority of the failures we witness are caused by a lack of oil.
After a while, it can grind all the way through, allowing one or both sides to break free and dance around the inside of the turbo housing, generating an unbearable noise and inflicting even more damage to the turbo housing’s inside.
However, it is important to note that even automobiles with a rigorous oil-change history are susceptible to turbocharger oil starvation, as new oil is insufficient to prevent this condition.
The banjo bolt (also known as a ‘union’ bolt) that secures the oil feed line to the cylinder head is the one who is responsible for the failure.
However, it is seldom updated as part of routine maintenance.
We have made the decision to provide a range of replacement turbochargers for the Subaru Impreza, WRX, Baja, Legacy, Outback, and Forester, as well as entire turbocharger kits that are thousands of dollars less expensive than what the dealer wants.
For those of you who don’t require the complete package, we also provide remanufactured turbos, brand-new Subaru OEM turbos, and even performance turbochargers that will transform your Subaru into a rocket on the road!

It’s likely your turbocharger has to be replaced. Fortunately, the professionals at BuyAutoParts.com are on hand to ensure that you receive the correct components that are guaranteed to be a perfect fit.

(’03-’05) – Help! Turbo failure on my Forester

If you were to undertake a quick examination of the turbo, would you check for all of these things as part of your routine procedure? So far, the consensus appears to be that the oil should be drained first to determine whether any metal shards are present in the system. If the turbo is undersized or does not include any metal, it should be replaced. If it’s big metal, I’m screwed and will have to completely rebuild the engine. As for the ‘short check of the turbo’, it’s unlikely to happen. Turbos have a tendency to work until they reach the point where they cease working.

Using oil, smoking from the tailpipe, and other signs of a faulty bearing are more obvious, and when these signs occur, people begin to investigate.
If you notice a problem with the turbo bearings early on, replacing the turbo and cleaning the intercooler and ducts should be sufficient solutions.
They just become entrenched in the carbon that coats the pistons’ surfaces.
The reason for the new (or rebuilt at the factory) short block is that it is extremely difficult for a shop or dealer to completely clean out all of the metal particles from the oil gallery passageways in the block after it has been installed or rebuilt.
Allow it to settle, then carefully drain off the top to see what’s in the bottom.
Assuming you are at the mercy of your technician, finding a cheap basement take-off TD04 turbo (which is what you already have) will be more difficult.
Look for a technician who is passionate about his or her work.
One more point: Subaru turbochargers were equipped with a fine mesh filter screen in the banjo bolts near the turbo in 2004.
and you already know where this narrative is going to end up.

There is a Subaru technical bulletin (or bulletins) available on this subject. If you do decide to replace the turbo, be certain that the screens are not included.

The 4 Most Common Subaru EJ255 Engine Problems – EJ255 Reliability

Subaru EJ255 engines are 2.5L turbo flat four engines that were used in a variety of US vehicles from 2004 to 2014. In addition to North America and Europe, the engine is still in use in other regions of the world as of 2020. It comes with a powerful engine that produces between 210 and 265 horsepower right out of the box. EJ255 engines are also well-known for their ability to react favorably to tune and modification. The EJ255 is a well-rounded engine that performs admirably. However, no engine is without flaws, and this isn’t an exception in this case.

What Subaru’s Use the EJ255?

The 2.5L EJ255 Subaru engine may be found in the following automobiles:

From 2006 to 2014, Subaru Impreza (WRX)
2004 to 2013 Forester XT
2005 to 2012 Legacy GT
2005 to 2009 Outback XT
And 2004 to 2006 Baja Turbo are among the models available.

In certain countries outside of the United States, Subaru EJ255 engines are still in use. The years and models listed above correspond to EJ255 variations sold in the United States. Although we may make specific references to individual models such as the WRX throughout, everything is in relation to the same 2.5L EJ255 engine. After that, let’s have a look at some of the most prevalent issues that occur with the EJ255 motor.

Subaru EJ255 Common Problems

Among the most prevalent EJ255 problems are the following: Here are a few short observations that we’ll go into more detail about later in this essay. Simply because these are referred to as ‘common difficulties’ does not imply that the problem will affect a majority of automobiles in the same category. Additionally, the 2.5L EJ255s are getting older, which means they’re susceptible to a variety of additional issues. On Subaru EJ255 engines, oil leaks, cooling system difficulties, and other issues can and do occur from time to time.

It is crucial to remember that when you tweak and modify the EJ255, some of these issues become more prevalent.

Having saying that, some issues may appear to be more prevalent on models such as the Impreza WRX.

1) Subaru EJ255 Turbo Failure

On the EJ255 engine, there are a number of factors that might cause turbo difficulties and failure. Before we get into the specific failures that have an underlying cause, let’s talk about how old we are. The majority of Subaru EJ255 engines on the road now are about 10-15 years old. Turbos have the potential to endure the life of a vehicle, but they are a high-wear component. Random turbo failures are relatively unusual, especially in vehicles with more over 150,000 miles on the clock. It could be stated the same thing about any turbo engine, not only these Subaru engines.

The oil filters on EJ255 engines are quite tiny.
A banjo bolt with a mesh filter in it is used to provide oil to Subaru EJ255 turbochargers.
A turbo with little or no oil flow isn’t going to perform well in the long run.
Alternately, you might consider replacing or cleaning the banjo bolt.
This occurs if the turbo discharges any metal into the oil, which can be taken up and dragged through the engine by the pistons and cylinders.

Although I don’t want to terrify anyone, this is just another reason why keeping up with maintenance on the banjo bolt, oil filter, and oil is really crucial.

EJ255 Turbocharger Failure Symptoms

On the Subaru EJ255, keep an eye out for the following symptoms, which might signal a problem with the turbocharger:

Exhaust smoke, louder turbo whining, loss of power, unable to achieve desired boost

The presence of smoke coming from the exhaust might indicate a turbo problem. However, it is possible that this is an indication of another disease as well. It’s generally a dead giveaway that your 2.5L EJ255 turbo’s whine has become noticeably louder than normal when it suddenly becomes louder than normal. You’ll also most likely notice a decrease of power as a result of the turbo failing to deliver adequate boost.

Subaru EJ Turbo Replacement

The Subaru EJ255’s turbocharger may be a significant financial investment. Used turbos may be found for less than $1,000, while new OE turbos cost roughly $1,500 to purchase. If you’re not doing it yourself, labor charges might add up to a significant amount of money. The process of replacing the EJ255 turbo is not difficult, but it does need some patience and time. Experts recommend that turbo repairs be left to people with prior experience or those who are ready to spend a weekend in the garage.

2) EJ255 Valve Cover Gasket Oil Leaks

We’re not going to spend much time on this. Because of any design problems in the EJ255, this isn’t a particularly widespread problem. Rather, it is an excellent example of a gasket that has been subjected to a great deal of wear and strain. The valve cover gaskets (VCG) are known to fail and leak oil as a result of wear and tear with time and usage. Due to the fact that the Subaru EJ255 is a flat four engine, there are two valve covers and gaskets to contend with. Look for VCG oil leaks to occur normally after 100,000 miles and when the vehicle is 10 years old.

Most of the time, it is not an emergency repair that has to be completed right away.

Subaru EJ255 VCG SymptomsReplacement

The following are some of the signs that the 2.5L Subaru engine is leaking oil:

Smoke coming from the engine area
A visible leak
The smell of burning oil

If you see smoke coming from the engine bay, look for it in the EJ255 valve cover locations. A visible leak from the VCG will be a dead giveaway that anything is wrong. If the oil is flowing onto heated areas, you may sense the smell of burning oil in the absence of this. The procedure for replacing the valve cover gaskets on a Subaru WRX EJ255 is rather straightforward. The coil packs, breathing hoses, and bolts that keep the valve cover in place must all be removed. For those who are less proficient at DIY, it may require a bit more time and patience.

Going to a repair shop, on the other hand, may add a few hundred dollars to the labor cost.

*A Quick Note Before The Next Topics

Engines with modifications tend to have greater issues with the ringlands, pistons, and rod bearings of the EJ255 engine. These failures do occur on factory engines from time to time, especially as the engine ages and accumulates miles. However, it’s crucial to remember that altering your WRX EJ255 may increase the likelihood of these difficulties arising in the first place. Quality, cautious tuning combined with appropriate supporting modifications can help to reduce the likelihood of a crash.

3) Subaru EJ255 RinglandPiston Problems

Having said that, the Subaru EJ255 is equipped with three piston rings. There are three rings in total: the upper and lower compression rings, as well as an oil ring. On the EJ255, the ringlands are the spaces between the three piston rings that are used. Cracks on the ringlands of the piston are the most common source of piston issues. It’s not a big concern on the ringland if there’s a little crack as long as it stays that way. Unless the engine is completely dismantled, it is unlikely to be noticed at all.

It is extremely dangerous when this occurs, and the repercussions are really severe.

It has the potential to destroy the cylinder walls as well.

It may, however, be possible to restore the structure depending on the amount of the damage.

EJ255 Ringland Failure Symptoms

Among the possible signs of EJ255 ringland or piston failure are the following:

Engine banging or ticking
Compression loss
Power reduction
Smoke coming from the exhaust pipe

If you lose a significant portion of the piston(s), you may hear a ticking or banging sound coming from the engine. Even while this isn’t usually the case, it can happen, especially if anything is in direct touch with the cylinder wall. Because the piston will no longer be able to effectively ‘close’ the combustion chamber, you will experience a loss of compression in that particular cylinder. As a result, there will be a loss of power. Also possible is that oil will blow-by the rings and reach the combustion chambers, resulting in the engine emitting smoke.

Subaru EJ255 Ringland/Piston Replacement

In the best case scenario, the motor will need to be disassembled in order to determine the degree of the damage. It may be possible to rebuild it, which would necessitate the purchase of a new piston and the machining of the walls. If the engine is not rebuildable, you will be looking at purchasing a new EJ255 engine. Repair costs will mount in any case, and this job should be left to the hands of highly qualified and experienced individuals to avoid further financial hardship.

4) Subaru EJ255 Rod Bearing Failure

Another internal engine issue for the EJ255 has arisen, and it is not particularly enjoyable to talk or think about. Rod bearings serve to link the connecting rods to the crankshaft in a fundamental way. EJ255 rod bearings are subjected to a great deal of wear, and they are frequently the first to fail when there is a problem with oil flow. In addition, a lack of maintenance history and insufficient oil change intervals increase the likelihood of bearing failure. The same may be true for increasing the amount of boost and power delivered to the Subaru EJ255 engine.

It is possible that you may blow a hole through the engine block or that the motor will seize.

There is a good chance that the EJ255 engine will not be re-buildable. Even if it is, the expenses of rebuilding the engine will very certainly outweigh the costs of acquiring a replacement motor.

EJ255 WRX Rod Bearing Failure Symptoms

Keep an eye out for the following signs and symptoms of rod bearing failure:

Metal shavings in the fluid
A loss of oil pressure
Rod knocking

Rod knock is a disconcerting sound that often rises in volume as the RPMs increase. The EJ255 isn’t going to have a particularly pleasant sound to it. Bearing wear can be detected and corrected before a catastrophic failure occurs. Occasionally check your engine oil for metal particles or send your engine oil in for an examination. You may also notice a decrease in oil pressure, which is particularly noticeable on cold starts. If you catch the problem early enough, you may be able to prevent your engine from being completely destroyed.

EJ255 Bearing Replacement

If you are detected in time, you may be able to get away with merely changing the bearings. This should be done to verify that the rod bearings did not cause excessive damage to the crankshaft surface while it was being disassembled. Otherwise, it may be necessary to machine the part, or it may be more cost-effective to replace the complete motor. Again, this task should be left to experienced technicians and do-it-yourselfers who are familiar with the process.

Subaru EJ255 Reliability

The question is, how dependable is the Subaru EJ255 engine, exactly? As a result, we are hesitant to call it a very dependable engine because a number of the EJ255’s most common faults are really significant and need expensive repair work. It’s crucial to remember, though, that the internet has a tendency to exaggerate the significance of some events and situations. It is possible and common for EJ255 engines to experience these problems and breakdowns. On the other hand, regular maintenance and oil changes go a long way toward avoiding internal engine damage from occurring.

If you’re in the market, seek for a vehicle that has been well maintained.

According to our research, we do not feel the EJ255 is nearly as dangerous as others may have you believe it to be.

That is not due to the fact that it is afflicted by an unending number of frequent difficulties.

Subaru EJ255 Common Problems Summary

The Subaru EJ255 is an excellent all-around engine. It has a 2.5L turbo flat four-cylinder engine that delivers outstanding performance and has its own distinct sound. In addition, there is a wealth of information and aftermarket support available for the EJ255. EJ255’s respond well to tweaks as well, although they have their limitations. You should use a conservative tune or improve the internals of your Subaru 2.5L if you plan on modding it. We do not consider the amount of difficulties associated with the EJ255 to be alarming.

Turbo failures, as well as internal difficulties including rings, ringlands, pistons, and rod bearings, may be extremely expensive.

Nonetheless, if you take good care of your EJ255, it is likely that it will provide you with an enjoyable and dependable experience. What have you found to be your most positive experience with the Subaru EJ255? Are you thinking about getting one? Please let us know by leaving a comment!

Subaru Turbo Problems: Is Your Turbo on Borrowed Time?

Do you believe your Subaru is suffering from turbo problems? This post discusses how to determine the cause of a turbo shaft breaking in half due to the owner’s failure to replace the banjo bolt and its filter. Learn a simple method for preventing turbo problems on your Subaru, as well as a simple method for repairing this one if yours has the banjo bolt and filter and you’d prefer not to replace it with a new one.

Why Does My Subaru Have Turbo Problems?

Those of you who read the 1A Auto Blog regularly may recall the 2006 Subaru Legacy GT project car that I purchased a few months back and started working on. If you haven’t already, you might want to start by reading Parts 1 and 2 of the project before proceeding to today’s article. On the other hand, you could like to go right to the meat and potatoes without wasting any time. I’m not going to hold it against you. In fact, that distinguishes you as a straight shooter, which is something I’ve always admired about you.

On a recent occasion, the new -ishVF40 turbo on the 2006 Legacy GT went out of control in hellacious way.
It was an unforgettable event that I will never forget.
The fact that I would have known what I know today a month ago would have prevented this horrific occurrence from occurring.
For my part, I can only blame myself for not doing more study into this automobile and its EJ25 engine, because all of this information is already there if you simply search for it.
When purchasing an automobile that you are unfamiliar with, it is imperative that you conduct extensive research.
Inquire with the individuals that operate the vehicles.
It WILL save you money and worry in the long run.

A Bad Banjo Bolt with a Filter

All right, let’s get down to business! When the red beauty was dragged home and placed in the dry, loving environment of the garage, I saw that the shaft inside the VF40 turbo had been entirely starved of oil, and it had broken in two at the center bearing. I immediately began to investigate. As a result, the turbine wheel was bouncing around inside the turbine housing, which was never ideal for achieving maximum efficiency. During operation of the engine, the sound may have been misinterpreted as the sound of someone putting steel chains into a wood chipper.

‘ The car had fresh new oil in it, with just around 2,000 miles on the oil that I purchased it with a few of months ago, and I knew that the previous owner had taken excellent care of it since she adored it, so I didn’t hesitate to buy it.

Because hundreds of other Subaru owners have experienced the same exact problem as me, I was surprised to find a 350+ page forum onLegacygt.comthat covered this identical problem in length.

There’s a small little (and dumb) filter hidden inside this banjo bolt.

That’s fantastic, isn’t it? No. That’s not the case. Because most individuals seldom, if ever, replace them, they are considered obsolete. Too much time spent driving causes the filter to clog, resulting in your turbo being starved of oil, which leads to an early death for your engine.

An Alternative Solution to a New Banjo Bolt

In any case, this bolt and the filter that it contains have no longer appealed to me, and I determined that there would be no manner in which I could replace them using the same design as they were originally installed. There has to be something better out there, like perhaps an oil supply line with a washable filter and a larger amount of oil? HUZZAH! Once again, the internet came to the rescue! A firm in California named ‘ Infamous Performance ‘ developed an oil feed kit that looks to be considerably superior to the OEM system in terms of performance.

There’s also an oil filter that’s both attractive and functional, and it can be readily cleaned out at your convenience.

Both components arrived quickly and performed well with no issues at all.

Fortunately, the car has been repaired, the birds are chirping, and a gorgeous red 2006 Subaru Legacy GT is once again on the road.

Do All Turbocharged Subarus Have a Banjo Bolt?

Now, for those of you who drive turbocharged Subarus, don’t get too excited just yet. The first step is to determine whether or not your vehicle was equipped with this banjo (union) bolt that contained the filter. (Not all Subarus are equipped with this banjo (union) bolt. In reality, the vast majority of them do not.) For the automobiles that do have it, however, it is placed on the rear of the passenger-side cylinder head and is responsible for holding the turbo oil feed line in place. One of the most helpful Subaru owners on the internet, known as ‘niemkij,’ wrote an excellent write-up on how to replace one of these bolts on his own.

For all intents and purposes, just changing this banjo bolt with a new one obtained from the dealer is all that is required of you.

Therefore, this little little turbo oil supply filter must be updated on a frequent basis, as previously stated.

Subaru Turbo Failure

Turbo failure is an all-too-common occurrence. There are a variety of variables contributing to this: One of the most important is the quality of the oil. Furthermore, many individuals are not aware that turbochargers require time to cool down after they have been operating. Turbochargers have the ability to spin at speeds in excess of 80,000 rpm. Because of the rapid speed, friction and heat can accumulate, which is the number one enemy of moving components. Subaru put screens in the turbo oiling system to prevent contamination.

You are not obligated to be a victim!

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. In most cases, a turbocharger will be used in conjunction with cooling systems to keep the oil and hot air cool.

Turbo Failure Symptoms

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

POWER LOSS

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.

WHINING ENGINE

Another surprising benefit of a turbocharger is that it actually makes the engine quieter by muffleing the sound of air intake, which helps to reduce noise pollution. But if you start hearing a loud, whining noise that sounds similar to a dentist’s drill or police siren, this might be an indication of turbo failure. Fortunately, this is rare. As the severity of the defect increases, the level of noise will increase. Whenever you hear a whine coming from your engine, you should take your vehicle to a competent technician for an inspection.

EXHAUST SMOKE

When using a turbocharger, one of the surprising benefits is that it actually makes the engine quieter by muffleing the sound of the air intake. But if you start hearing a loud, whining noise that sounds similar to a dentist’s drill or police siren, this might indicate that your turbo is failing. The noise will worsen as the severity of the defect increases. Whenever you hear a whine coming from your engine, you should take your vehicle to a skilled technician for an examination.

CHECK ENGINE LIGHT

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.

OIL/LUBRICATION

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.

DAMAGED SEALS

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.

FOREIGN OBJECTS/DEPOSITS

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.

WEARTEAR

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.

Think you have a blown turbo? – Here’s what to look for

Our experts at Garage Express in North London are familiar with and examine many current cars’ turbochargers, which are more often referred to as a turbo, which assist in increasing the engine’s power. In theory, the turbo should outlast the automobile, however it is possible that the turbo will become damaged over time. Damage to the turbo can be caused by a variety of issues, including:

There is not enough oil in the system. The wrong type of oil was used
Detailed information on the vehicle’s age and mileage
Deteriorated seals (resulting in oil entering the exhaust system)

What are the signs of a blown turbo?

The failure of the turbocharger might be signaled by any number of different signs. The good news is that if you pay careful attention to how your car is behaving, you can frequently detect the tell-tale signs of the most common difficulties and thereby rule out probable turbo issues, eliminating the need for a garage to run a diagnostic test to determine the source of the issue. The following are the most prevalent signs that you may have a blown turbo:

There is a notable reduction of power in the vehicle. The automobile appears to accelerate slowly and with a lot of noise
The automobile is unable to maintain high speeds with ease. A cloud of smoke is rising from the exhaust pipe. On the dashboard, there is an engine problem light illuminated.

Can you drive with blown turbo?

The longer you drive your car with a blown turbo, the more damage the engine will sustain and, as a result, the more expensive it will be to fix it in the future. The car will still drive if the turbo is damaged, but it would be far preferable to stop driving it and have it towed to a garage where the turbo may be fixed or a replacement turbo fitted.

The longer a blown turbo is allowed to go without being repaired, the more harm it may do to the car’s engine and transmission.

What do you do if your turbo is blown?

Once it has been established that the turbo has failed, there are two solutions available to you. In the first instance, you can purchase a fresh new turbocharger and have it installed. Alternatively, if you want to keep the expenses down, you may recondition and fix the turbo you currently have. Unsurprisingly, purchasing a new turbo is preferable because it comes with a longer guarantee and is expected to last longer than purchasing a refurbished turbo in most cases. Clearly, given the difficulties listed above, there are several things to check for and consider if you discover that your turbo is no longer working properly.

Our technicians and mechanics will be happy to assist you with your vehicle.

r/subaru – 2013 WRX turbo failure, driven too lightly!?

As a result, I took my factory 13 WRX hatch to my local Subaru store since it was rattling under low RPM. Overall, the turbo was replaced due to a faulty wastegate seal on its exhaust side, which was loose and rattling. Despite the fact that it had just 45k miles on it, it was covered by the powertrain warranty and was replaced at no cost to me. This is particularly bizarre since, when the repair technician sat me down, he indicated that the turbo/engine was otherwise in perfect condition and that the failure may have occurred because I did not drive the car aggressively enough!

Due to the fact that it is my daily driver and that I have two children in the car most of the time, I have not pushed it too hard on this vehicle.

My reaction to the advise that was provided to me is still hilarious, and I am delighted to follow it!
