Oil leak Cobalt Mailbu G5?

  • I have an Oil leak Cobalt Mailbu G5 GM reports that an oil leak that appears to be coming from behind the starter motor is actually coming from a leaking oil pressure switch. The leak appears on 2.2L 4-cylinder engines made prior to 2/19/07. GM has issued a new part that holds up better.

Are oil leaks worth fixing?

Low oil levels due to a leak is one of the quickest ways to do major engine damage and end up with an even higher repair bill. Since oil leaks can be so destructive, the cost of repairing the leak is almost always worth it to make sure your car stays running and doesn’t leave you stranded or worse.

What causes oil to leak on alternator?

Causes of a Bad Alternator Seal The design of the alternator seal and gasket combination is easily prone to breakage. The seal dries out and starts to crack over time and this then results in oil leaking from the engine and into the alternator.

How much does it cost to fix an oil seal leak?

Oil leak repair is a serious thing to address, and typically the repair cost starts from $85 to $155 going up from there. And you’ll have to pay the labor cost ranging between $70 and $1120, while other small seals on top can cost you between $10 and $30.

Is it OK to drive a car with an oil leak?

Driving a car with an oil leak can be dangerous for you and other road users. Oil can become flammable when it reaches a certain temperature and parts of your vehicle’s engine can get very hot, which may result in a fire. However, oil can also cause damage to seals and rubber hoses, which could result in a breakdown.

Are small oil leaks normal?

While it might seem easy to ignore a few drops of oil on your driveway, it’s always a bad idea. Left unaddressed, a small oil leak can grow into a larger, much more expensive repair. Plus, if the leak worsens while a vehicle is in operation, it can cause the engine to seize.

What happens if oil leaks on alternator?

Generally does not create any harm in small quantities, but if more quantity of hot oil gets into the alternator, it could burn out or short electronics leading to alternator failure.

Can an oil leak ruin an alternator?

However, oil leaking on the alternator due to leaking valve cover gaskets can cause it to fail. I would recommend having the alternator replaced if it has oil leaking on it as well as resolving the valve cover gasket leak to prevent it from happening again.

Can I spray WD40 on alternator?

You wouldn’t want to clean the alternator with WD40, as it would weaken the winding insulation. Hence, it can further cause some damages to the motor. Again, spraying WD40 directly to the alternator may ruin it, as the liquid may get to spots where it shouldn’t get to and cause harm.

What is Blue Devil?

BlueDevil Head Gasket Sealer (#38386) will repair and seal leaks in blown head gaskets, warped or cracked heads, heater cores, and freeze plugs. BlueDevil contains no solid or particulate matter, and will not clog or harm your engine. It bonds to metal, aluminum, cast, alloy, or plastic, and it’s safe and easy to use.

Can you fix an oil leak at home?

Thankfully, in many cases, you can repair minor to moderate oil leaks at home with one of our Bar’s Leaks engine repair products. In many cases, oil leaks are around the oil pan gasket or at the oil filter or plug. Start by tightening any loose bolts, your filter or your plug (oil filters are common culprits here).

Does synthetic oil cause leaks?

Switching to synthetic oil causes leaks: Generally, switching to synthetic oil does not cause leaks. It is true that synthetic oil is thinner than conventional oil and therefore flows more easily. If there is a spot where oil could leak out in your engine, then synthetic oil is more likely to leak than conventional.

How long can a car run with an oil leak?

Q: Can I still drive with an oil leak? A: It’s always advisable not to drive if your vehicle has an oil leak, but short distance drives, less than 10 miles, are not as risky when it comes to lowering your oil levels to a dangerous point.

Can my car catch on fire from an oil leak?

There is a very small chance that a slight oil leak would cause a complete engine fire. The oil that is leaked onto the engine will burn, and cause smoke as the result, but this is not the same as an engine fire. When these components completely fail, the crankshaft is not lubricated and can ruin the engine.

When should I be concerned about oil leaks?

The most critical engine oil leaks are those that starve your engine of oil. If you see a large puddle on the ground, don’t try starting your engine. You may not have enough oil left to lubricate your engine and can cause permanent damage that can only be repaired by an engine rebuild or replacement.

Fix for oil leak on ’08-09’s

We’ve had several new vehicles with strange oil leaks from below the ac compressor, and GM has been doing an engineering study into the leak for the past few months. They’ve now gotten enough leaky cars to look at to make a determination on the leak’s location. Here’s what they discovered and what they recommend we do as a result. NO, this is not a recall, campaign, or other such initiative. NO, you do not need to get this done if your car isn’t leaking oil in the manner described above. Models: Chevrolet Cobalt, HHR, and Malibu models from 2008 to 2009.

Cause According to engineering, the source of certain engine oil leaks may be related to bedplate porosity at the rear A/C bolt hole mounting bracket, which is located at the back of the vehicle.

If it is determined that the engine oil leak is caused by a bolt hole in the rear A/C mounting bracket, the following repair process should be followed to rectify the situation.

After the engine has cooled, use a low VOC brake cleaner (P/N 12378392 or an equivalent) to wipe the existing oil out of the hole and off the head of the bolt, then replace the bolt.

Reinstall the bolt after applying a Teflon pipe thread sealant (P/N 12346004 – LOCTITE 565 or equivalent) to the threads of the bolt. General Motors Corporation reserves all rights. 2008 General Motors Corporation.

Part 1 -How To Test For A Blown Head Gasket (2.4L Cobalt, HHR, Malibu, G5, G6, Solstice)

The 26th of February, 2019 It was last updated on June 19, 2020. Contributed by:Abraham Torres-Arredondo 910 is the article ID number. You may use this lesson to determine if the head gasket on your 2.4L Chevrolet car has been damaged or not. It is not difficult to check for a blown head gasket. The majority of the time, there are four tests involved.

Two of the four tests need no use of any tools at all. Compaction testing and block testing are the other two tests for which you will need to use tools. Each of the four exams is thoroughly described. NOTE: This guide relates to the 2.4L engines found in the following General Motors vehicles:

  1. 2.4L Chevrolet Cobalt 2006, 2007, 2008

Symptoms Of A Blown Head Gasket

A blown head gasket can manifest itself in a number of different ways. However, they are often classified into one of two groups. If your 2.4L four-cylinder engine in your GM car has a blown head gasket, it will crank but will not start in the first category. The engine starts in the second category, but it overheats before it can get going. Aside from the overheating of the engine, you’ll notice one or more of the following signs and symptoms:

  1. The exhaust has a distinct fragrance that reminds me of antifreeze being burnt. As soon as the engine is started and allowed to run, white smoke emerges from the exhaust. In most cases, the P0300 misfire fault code is associated with a rough idle condition. Specific misfire cylinder codes, such as P0301, P0302, P0303, P0304, P0305, or P0306, are available. When you speed the car, there is a lack of power

When you burn antifreeze, the exhaust has a distinct fragrance. When the engine is turned on and running, white smoke flows out of the exhaust. The P0300 misfire error code is often associated with a rough idling situation. P0301, P0302, P0303, P0304, P0305, and P0306 are examples of specific misfire cylinder codes. Inability to accelerate the car when it is in neutral.

TEST 1:Engine Oil The Color Of Coffee With Too Much Creamer

Crankcase coolant mixing with engine oil is the most prevalent indication of a blown head gasket in a vehicle. As a result, the engine oil develops a hue that resembles coffee with too much creamer. Using the engine oil dipstick, we can quickly and easily determine the condition and color of the oil by simply drawing it out and seeing the color of the oil that is adhered to it. And this will be the first of many tests to come. The following are the stages involved in the test:

  1. 1: Open the hood of your car
  2. 2: Remove the engine oil dipstick
  3. 3: What color is the engine oil? 1: What color is the engine oil? It should be a creamy tan/off-white tone that looks like coffee with too much creamer, to begin with. 2.)The engine oil will be the same color as it always has been

Let’s have a look at your test results: CASE 1: The engine oil that is clinging to the dipstick is a regular shade of brown. This is the right answer, and you should expect a positive test result. It is necessary to unscrew the radiator cap and then crank the engine in order to determine whether any engine coolant is discharged. Please see TEST 2: Coolant Shooting Out From an Opened Radiator for more information on this test. CASE 2: The oil that is clinging to the dipstick has the appearance of coffee with much too much creamer.

The 4 Most Common GM 2.2 Ecotec Engine Problems

The 2.2L Ecotec engine made its debut in the Saturn LS1 in 2000 and remained in production until 2011, when it was superseded by the 2.4L Ecotec. Chevrolet, Pontiac, Oldsmobile, and Saturn are all brands that employ the 2.2 Ecotec engine in their cars, as are Opel and Holden in other countries, according to the company. The L61 engine code was frequently used in conjunction with the 2.2L Ecotec. Introducing in 2007 came the Gen II L61, an improved version of the L61 2.2 Ecotec that replaced the L61 2.2.

The torque produced by Gen I 2.2s ranged from 135 to 155 lb-ft.

This engine was a dependable, fuel-efficient, and reasonably priced alternative for customers who did not want a high-performance engine.

What cars use the 2.2L Ecotec?

Between 2000 and 2011, General Motors utilized the 2.2 Ecotec in Chevrolet, Pontiac, Oldsmobile, and Saturn automobiles. Aside from that, there were considerable upgrades to the engines in 2007, and as a result, some of the faults may be limited to Gen I models only. The L61 engine code was utilized to create the vast majority of the 2.2s on the market. However, a few versions, such as the L42, Z22YH, LAP, and LE8, were available for purchase. Because of their limitations, the L42 and Z22YH aren’t explored in depth in this section.

It was the L42 that was the natural gas variation of the L61, and the Z22YH was the only direct injection type that was offered outside of North America. We’ll go through which exact engine codes are utilized by different vehicles in the section below.

Gen I GM 2.2 L61 Engine

  • Various 2001-2006 Opel/Vauxhall/Holden models
  • 2002-2005 Chevrolet Cavalier
  • 2005-2006 Chevrolet Cobalt
  • 2006 Chevrolet HHR
  • 2004-2006 Chevrolet Malibu
  • 2002-2004 Oldsmobile Aero

  • And other issues.

1. 2.2 Ecotec Timing Chain Failure

Failure of the timing chain tensioner; leaking intake manifold gaskets; and oil leaks are all possible problems. Repairing Gasket Leaks; Performing High Mileage Maintenance

What happens when the timing chain fails?

The timing chain tensioner on the 2.2 Ecotec is the most common cause of misfiring engines in this model. When the tensioners fail, the chain becomes slack and begins to slip off the sprockets. A faulty timing chain can cause the engine’s timing to ‘jump gears’ and put the timing of the entire engine out of whack. If the timing chain jumps too many gears, the piston and valves can clash, causing catastrophic engine damage. If the timing chain leaps too many gears, the piston and valves can collide, causing catastrophic engine damage.

The concerns outlined below will occur even if the chain is just gently wrenched from side to side.

2.2 Ecotec Timing Chain Failure Symptoms

  • The timing chain tensioner on the 2.2 Ecotec is the most common cause of misfiring engines in this engine type. A failure of the tensioners results in slack in the chain, which eventually causes it to slip off the rollers. Timing chains that are not trustworthy might cause the engine’s timing to ‘jump gears’ and put the engine’s timing out of whack completely. Because of this, if the timing chain is shifted too many times, it can cause catastrophic engine damage. If the timing chain is shifted too many times, the piston and valves can collide, resulting in catastrophic engine damage. Because of this, it is sad that timing chain failure on the 2.2 Ecotec occurs nearly always instantly, but in most other situations, it occurs over a period of many minutes or hours. The concerns outlined below will occur even if the chain is just minimally jerked during the jerk. Avoid driving if at all possible to prevent further engine damage. The timing is improper.

For more information on timing chains, please see our complete guide on timing chain failure.

2. Leaking Intake Manifold Gaskets – GM 2.2 Ecotec

The intake air filter, intake pipe, and the intake manifold are all used to bring air into the engine. When the 2.2 Ecotec’s intake system pulls in air, the intake manifold distributes it equally throughout the engine’s four cylinders, resulting in a more efficient engine. The intake manifold is linked to the engine block by means of bolts and is made of a thick plastic composite material. The intake manifold and the engine block are connected via gaskets. Individual gaskets for each cylinder are used in the 2.2 Ecotec, as opposed to the usual one-piece manifold gaskets used on other engines.

As is the case with any gasket, they will ultimately fail as a result of regular wear and use.

There is a higher rate of failure of Gen I gaskets compared to Gen II gaskets on 2.2s.

The breakdown of a gasket is a regular occurrence.

Symptoms of Bad Intake Manifold Gaskets

  • Misfires and harsh idling
  • A lack of power, acceleration, and other characteristics
  • The engine oil cap contains a milky-looking material. AFRs that are high owing to insufficient airflow

When a leaky cylinder has a damaged gasket, a misfire is nearly invariably the result of the leak. A leak causes air to escape from the manifold, resulting in insufficient air being delivered to the cylinder to adequately burn the fuel.

3. OilGasket Leaks

By the time some of these 2.2 Ecotecs reach their 20th anniversary, oil leaks and other frequent maintenance difficulties will begin to manifest themselves. Despite the fact that oil leaks are not a ‘common’ problem, older engines with more than 150,000 miles on them will eventually begin to exhibit indications of wear and tear. The valve cover gasket and various seals, as well as the oil pan gasket and intake manifold gasket, are all included in this category. The failure of a gasket is the most common cause of most of these problems.

Time it’s normally safe to continue driving with an oil leak for a while, be sure you don’t run out of engine oil because this might cause the timing chain to break.

Gasket replacement is a low-cost project that may be completed by the do-it-yourselfer. While oil pan gaskets and main seals are very inexpensive, the work required to replace them can be extremely pricey.

4. General High Mileage Maintenance

As some of these 2.2 Ecotecs reach their 20th anniversary, oil leaks and other regular maintenance difficulties will begin to surface. However, even if oil leaks aren’t a ‘common’ problem, older engines with more than 150,000 miles on the clock will ultimately begin to exhibit indications of wear and tear. The valve cover gasket and other seals, as well as the oil pan gasket and intake manifold gasket, are all covered under this provision. Generally speaking, most of these problems are caused by gasket failure.

Time it’s normally safe to continue driving with an oil leak for a while, be sure you don’t run out of engine oil because this might starve the timing chain and cause it to break prematurely.

But while the replacement of the oil pan gasket and main seal is affordable, the labor involved in the repair or replacement can be fairly expensive.

2.2 Ecotec Reliability

In general, the 2.2 Ecotec is a reliable engine with low maintenance requirements. Because of a typical source of timing chain failure, models from 2004 and older are less reliable. Once a 2005 or later model’s engine has collected a large amount of mileage, there aren’t any typical concerns that need to be addressed outside of basic maintenance. Both the transmission and the engine are constructed using heavy-duty components such as the block, head, and other internals to ensure long-term performance.

  • It is possible to drive more than 250,000 miles on a 2.2 Ecotec engine with appropriate maintenance.
  • The addition of an intake or exhaust system to this engine will have no influence on its lifetime, but the addition of forced induction, such as a turbocharger or supercharger, may have a detrimental impact on its dependability and performance.
  • Despite the fact that additional power puts more strain on engine components, the engine will not fail catastrophically if just 150 horsepower is produced.
  • What are your opinions on the dependability of the 2.2 Ecotec engine?

A reliable engine in general, the 2.2 Ecotec is a good choice. 2004 and older models are less reliable due to a common source of timing chain failure. There aren’t any typical concerns with a 2005 or later model’s engine when it has acquired a substantial amount of mileage, except than the usual maintenance. Using heavy-duty components such as the engine block, head, and other internals, both the transmission and the engine are engineered to survive for years. When problems occur, the ancillary engine systems and front suspension components are the most usually seen.

Changing performance has the potential to impair reliability, so be mindful of that.

Owing of their modest output, they have a lengthy lifespan, which is mostly due to this.

The increased stress placed on the engine’s internals and critical components as a result of forced induction increases the likelihood of a catastrophic breakdown of the engine. Your views on the 2.2 Ecotec’s dependability would be much appreciated.

The 4 Most Common GM 2.2 Ecotec Engine Problems – 2.2L I4 Ecotec

The 2.2L Ecotec engine made its debut in the Saturn LS1 in 2000 and remained in production until 2011, when it was replaced by the 2.4L Ecotec engine. This engine is found in a variety of General Motors brands, including Chevy, Pontiac, Oldsmobile and Saturn, as well as Opel and Holden in overseas markets. The 2.2L Ecotec engine was primarily produced under the L61 engine code designation. The L61 2.2 Ecotec underwent a number of modifications in 2007, and was renamed the Gen II L61. Among the modifications were a stronger block, an updated cylinder head with wider exhaust ports, a new camshaft design, and coil-on-plug ignition, among other things.

The upgrades made to the Gen II engines resulted in power ratings ranging from 145 to 149 horsepower and 150 to 152 pound-feet of torque.

What cars use the 2.2L Ecotec?

The 2.2 Ecotec engine was used by General Motors from 2000 to 2011 in vehicles under the Chevrolet, Pontiac, Oldsmobile, and Saturn brands. Furthermore, there were significant engine upgrades that occurred in 2007, and as a result, some of the issues may only afflict Gen I cars. The L61 engine code was used in the production of the vast majority of 2.2s. Although there were several distinct models, the most notable of them were the L42, Z22YH, LAP, and LE8. Due to the restricted capabilities of the L42 and Z22YH, we will only cover the other models listed below.

We’ll go through which automobiles utilize the specific engine code in the section below.

Gen I GM 2.2 L61 Engine

  • Chevy, Pontiac, Oldsmobile, and Saturn brands all utilized the 2.2-liter Ecotec engine from 2000 to 2011. Additionally, there were significant engine changes that occurred in 2007, and as a result, some of the issues may only be present in Gen I cars. Engine code L61 was used for the majority of 2.2’s that were built. Although there were several distinct models, the most notable of which were the L42, Z22YH, LAP, and LE8. Due to the restricted capabilities of the L42 and Z22YH, we will only discuss the rest of the models in this section of the article.

1. 2.2 Ecotec Timing Chain Failure

The timing chain is in charge of regulating the opening and shutting of the engine’s intake and exhaust valves, among other things. In order for an engine to operate effectively, the valves must open and close with extreme precision from a timing standpoint. Using a timing chain that looks similar to a bicycle chain, the timing chain controls the timing of the engine by encircling gears or sprockets that are linked to the cam and crankshafts. Tensioners and guides are also used in timing chain systems.

  • Guides are plastic components that help to keep the chain moving in the right direction.
  • The timing chain is contained under a cover, which is lubricated with engine oil to ensure proper operation.
  • This issue is particularly prevalent in versions manufactured between 2000 and 2004.
  • When not enough oil is obtained, the tensioners get starved of lubrication, resulting in excessive friction and heat being generated, ultimately leading to the failure of the tensioners.

Having said that, timing chains are still prone to failure on any engine, regardless of the manufacturer. In later model 2.2s, low oil levels and engine overheating are two typical causes of timing chain failure, both of which are preventable.

What happens when the timing chain fails?

It’s common for the 2.2 Ecotec to have issues with its timing chain tensioner, which is the basis of the problem. When the tensioners fail, they allow for excessive slack in the chain, resulting in a sloppy chain. When the timing chain becomes slack, it has the potential to ‘jump gears’ or ‘jump sprockets,’ throwing the entire engine’s timing out of sync. It is possible for the timing chain to jump too many gears, leading the timing to go out of synch to the point where the piston and valves collide, causing catastrophic engine damage.

If the chain just moves a small amount, you will experience the symptoms listed below.

2.2 Ecotec Timing Chain Failure Symptoms

  • Misfiring cylinders
  • Knocking sounds coming from the engine Idling is poor
  • The engine will not start. Overall, the performance was awful. Metal flakes are present in the oil.

Check out our in-depth guide on timing chain failure for additional information on timing chains in greater detail.

2. Leaking Intake Manifold Gaskets – GM 2.2 Ecotec

In order for air to enter the engine, it must pass through the intake air filter, into the intake pipework, and into the intake manifold. 2.2 Ecotec’s intake manifold is responsible for distributing air from the intake system to each of the four cylinders in an equal and efficient manner. Intake ports on the engine block are directly connected to the manifold, which is composed of strong plastic and attaches directly to the engine block. Gaskets are used to seal the gap between the intake manifold and the block.

Rubber gaskets with a round form are used to seal the joints.

Gaskets are subjected to a great deal of pressure, vibration, and extremely high temperatures in their service.

When the gaskets fail, it is possible for air to escape from the intake system, resulting in a reduction in performance.

Symptoms of Bad Intake Manifold Gaskets

  • Misfires and harsh idling
  • A lack of power, acceleration, and other characteristics
  • The engine oil cap contains a milky-looking material. AFRs that are high owing to insufficient airflow

As a result of the fact that the gaskets are customized for each cylinder, misfires are more prevalent with the leaky cylinder. Air is allowed to escape from the manifold as a result of leaks, and the cylinder does not receive enough air in relation to the amount of fuel it is receiving, resulting in improper combustion.

3. OilGasket Leaks

The oil leaks and other regular maintenance issues that will begin to occur when some of these 2.2 Ecotecs reach the age of 20 or more years will become more prevalent. Despite the fact that this isn’t necessarily a ‘common’ problem, oil leaks are certain to begin to develop after these older engines have accumulated more than 150,000 miles on them. Gaskets such as the valve cover gasket, the head gasket, the oil pan gasket, the main seals, the intake manifold gasket, and so forth are susceptible to leaking.

Gaskets naturally degrade over time as a result of pressure and heat, and this can result in oil leaks and air leaks in the engine.

For the do-it-yourself enthusiast, replacing gaskets may be a relatively inexpensive project. In contrast, while replacement parts such as main seals and oil pan gaskets are inexpensive, the labor required to replace items such as these may be rather expensive.

4. General High Mileage Maintenance

It is likely that oil leaks and other frequent maintenance issues will begin to appear when some of these 2.2 Ecotecs reach their mid-20s or later. Despite the fact that this isn’t necessarily a ‘common’ problem, oil leaks are certain to happen after these older engines have accumulated more than 150,000 miles under their belts. Gaskets such as the valve cover gasket, the head gasket, the oil pan gasket, the main seals, the intake manifold gasket, and so on are all susceptible to failure. Approximately 80% of these failures are the consequence of a failed gasket.

Despite the fact that oil leaks are normally OK for driving on for a length of time, be sure you don’t run out of engine oil because this might cause the timing chain to break.

In contrast, while replacement parts such as main seals and oil pan gaskets are inexpensive, the labor required to replace items such as these may be rather costly.

2.2 Ecotec Reliability

In general, the 2.2 Ecotec is a dependable engine with low maintenance requirements. Due to the high frequency with which timing chain failure occurs, models from 2004 and before tend to be less trustworthy. Once the engine has accumulated a significant amount of miles, 2005 and later models are almost trouble-free, with the exception of routine maintenance issues. The transmission and engine block, head, internals, and other components are all extremely durable and will endure for the duration of the engine’s life.

  1. With proper care, the 2.2 Ecotec is capable of traveling more than 250,000 miles before needing to be replaced.
  2. However, although adding an intake or an exhaust to this engine will have no influence on its lifetime, forcing induction, such as a turbocharger or a supercharger, would have a detrimental impact on its overall durability.
  3. The usage of high-powered engines creates stress on its internal components; nonetheless, 150 horsepower is not nearly enough to trigger a catastrophic engine breakdown.
  4. What has been your experience with the 2.2 Ecotec’s dependability?

  • THE ENGINE IS IN USED CONDITION. What is a ‘core’ or a ‘core charge’ and how do they differ? Your car’s core is a term used in the automotive industry to refer to the outdated, problematic engine that is currently in your vehicle. A core fee is a refundable deposit that is placed with us to ensure that the core engine is returned in its original condition. On the core engine, we will cover the cost of return shipping. We will reimburse all core prices as soon as the old faulty engine is sent to our facility. This generally takes 2 – 3 business days, depending on the workload. Warranty on replacement parts is for 90 days. PLEASE READ AND UNDERSTAND THE FOLLOWING: Engine warranties are only valid for manufacturing faults in the block, heads, pistons, crankshafts, camshafts, rockers, and oil pumps, and are not applicable to any other parts of the engine. Everything else that may be offered is referred to as ‘Accessories and Extra Parts.’ For any such connected items, including but not limited to: switches, sensors, cable assemblies, fuel injectors, electronic components, belts (including timing belt/chain), hoses, water pumps, manifolds, and oil pans, no guarantee is offered. If the heat tabs on the engine are melted or missing, they are replaced. The warranty will be revoked. Checklist for the Installation: (Failure to comply with the following will result in the voiding of the warranty.)
  • To determine the root cause of the original engine failure and to perform the necessary repairs, Ascertain that the engine in question is the same application as the one that is being replaced. Remove any and all computer diagnostic codes from the car prior to installation. Replace the oil pan and pick-up tube with new ones. Gaskets and seals (front seal, rear main seal, valve cover gaskets, oil pan gaskets) should be inspected and replaced as needed. To prevent leaks from forming on crankshaft bolts that have been drilled through, sealant must be applied. Reinstalling a new thermostat gasket Replace the timing belt if necessary. Remove all of the ‘cap-plugs’ orifice covers from the system. Water pump should be replaced. Replace the sparkplug wires with new ones. Replace the flywheel and bolts with new ones. It is necessary to exchange any accessory parts that are attached to ensure good fit (mounts, intake manifold, exhaust manifolds, distributor, sensors, etc.). Before attempting to start the engine, turn off the gasoline and ignition. Allowing the oil to prime in the manner specified by the manufacturer will be possible. Engine oil, oil filter, air filter, fuel filters, and coolant-antifreeze should all be changed. Extra oil and coolant should be drained from the exhaust system. If your vehicle is equipped with an engine oil cooler, you must replace the radiator or external cooler. Check to see that the cooling system has been flushed and is operating correctly. If the heat tabs on the engine are melted or missing, they are replaced. The warrantee will be null and invalid.
  • Warning! On a 2.3L engine, incorrect removal and replacement of the harmonic balancer will result in movement of the timing chain and bent valves as a result of the movement.

Oil Leaking From a Sensor Above the Starter

A head gasket on my 2002 Chevrolet Malibu LSI was just blown due to an oil leak. It was necessary to take the heads to a machine shop where they were inspected and machined in addition to receiving new valve seals. The engine is completely reassembled and operating well, with no leaks or difficulties everywhere, with the exception of an oil leak that has me perplexed. When the head gasket failed, the leak was already present. An unidentified sensor that is inserted into the block under the front exhaust manifold, above the starter, appears to be the source of the leak.

  • There is just one wire that connects to it, and the plug is coated with oil to prevent corrosion.
  • Have you ever seen or heard something like this before?
  • Answer: It appears that the item you are describing is the oil pressure transmitting unit, which is also known as the oil pressure sensor in certain circles.
  • This sensor is located in an oil galley in the engine and has full oil pressure behind it, indicating that it is operational.
  • It will only set you back approximately $20.
  • So make sure you’re not immediately underneath it when you take it out.

Chevy Malibu Engine Ticking

After an oil leak caused a head gasket to blow on my Chevrolet Malibu LSI in 2002, I decided to replace it. In addition to new valve seals, the heads were sent to a machining facility where they were evaluated and machined. With the exception of an oil leak that has me stumped, the engine is fully assembled and working properly, with no leaks or issues whatsoever. As soon as the head gasket failed, a leak appeared. An unidentified sensor that is inserted into the block under the front exhaust manifold, above the starter, appears to be the source of the problem.

  1. A single wire is connected to it, and the plug is coated with oil to keep out moisture.
  2. Has anything like this ever occurred to you or been mentioned to you before?
  3. In your description, it appears that the oil pressure transmitting unit, also known as the oil pressure sensor, is the component in question.
  4. Because this sensor is located in the engine’s oil galley, it receives full oil pressure.
  5. A few dollars more than that and you’ve got yourself a great deal.

The removal of this part may result in some oil leaking out of a hole in the block. Take care not to stand directly beneath it as you take it out of the ground. Also, avoid hitting the starting cord with your tool, as this can result in a large spark and the possibility of a fuse blowing.

Replacing the crankshaft front oil seal on a GM 2.2L Ecotec engine in a Cavalier, Cobalt, HHR, Malibu, Grand Am, Sunfire and more

There was a significant leak when this seal failed on a 2003 Chevrolet Cavalier equipped with GM’s 2.2L Ecotec engine. A significant source of leakage is the crankshaft front seal, which is located at the front (belt end) of the engine and is the most common location for leaks. The serpentine belt will have a tendency to become oil soaked and disperse the oil all over the bottom of the engine, resulting in drips appearing all over the place. In comparison to many other automobiles, this repair is straightforward.

Aside from the Cobalt and HHR, other General Motors vehicles powered by this engine include the Malibu and Alero, the Grand Am, the Sunfire, the Saturn L series, and the Ion, as well as various Opel and Vauxhall vehicles.

  • Safety precautions include safety glasses and gloves. The following tools are required: A hydraulic or scissors jack, jack stands or significant wood supports, 19, 21, and 7 mm sockets, a 24-inch breaker bar, 3/8 and 1/2′ ratchets, a pry bar or other sprocket holding tool, and a tiny seal prying tool Crankshaft front oil seal (Fel pro TCS 46112), new crankshaft pulley bolt, serpentine belt (if necessary), rags, engine degreaser, grease, and oil are among the parts and supplies required. Materials are expensive. Seal $7.50 (Napa), pulley bolt $7 (GM), serpentine belt $21 (Napa), and consumables $4.00 were all purchased at the store. $31.50 in total
  • The job’s labor cost at the shop was $100. Time estimate for a home mechanic: 2 to 3 hours

1) Remove the right front tire’s 19mm lug bolts and set them aside. 2) Raise the front of the vehicle and secure it using supports. Behind the wheel, I used two railroad ties. 3) Remove the right front wheel from the vehicle. 4) Remove the cover from the right front wheel well. This is a difficult cover to remove, and it will take some time to complete. It is secured in place by eight or ten 7mm hex screws. The one at the very top is the shortest. It’s also necessary to remove two panel fasteners: one near the horn in the front and another way down low behind the wheel.

5) Disconnect the battery from the computer.

Release the strain on the serpentine belt by sliding the tensioner higher, which releases the stress on the belt.

8) Remove the crank pulley from the engine. Mine just slipped off the table. It may be required to employ a puller in this situation. On the pulley, there are three holes that may be used to attach a puller to it. 9) Discard the faulty seal. This one may be removed by prying along the underside of the container. I used a prying tool that was six inches long and it came out effortlessly. 10) Thoroughly clean the route of the belt. An engine degreaser and plenty of rags will come in handy in this situation.

  1. Apply a thin layer of grease to both sealing surfaces.
  2. 2) Reinstall the crankshaft pulley in its original position.
  3. 3) Install a new crank shaft pulley bolt and tighten it to 74 foot pounds, plus an extra 75 degrees of rotation, to complete the installation.
  4. Two individuals are required for this, one holding the pry bar and the other wielding the torque wrench to be effective.

4) Attach the serpentine belt to the drive shaft. It wraps around the exterior of the alternator, the AC compressor, and the crank pulley before passing under the tensioner and into the battery.

5) Replace the wheel well cover. 6) Install the wheel and tighten the lug nuts only to the specified torque. 7) Raise the car to the point where the stand can be removed, then lower it to the ground. 8) Reconnect the battery. 9) Tighten the lug nuts and check for leaks.
