Subaru 2.4 Turbo Engine Problems

If you have a Subaru 2.4 Turbo engine, you may be experiencing one or more of these common problems. Listed below are the common problems, their causes, and remedies. If you suspect that you are experiencing any of these problems, don’t ignore them – they can be a sign of a larger issue. Read on to learn more. The best way to diagnose your car’s underlying problems is to do a thorough inspection.


A symptom of a malfunctioning turbo is misfiring. There are several possible causes for this problem, including a vacuum or boost leak, a faulty ringland on the piston, or tight exhaust valve clearances. A misfire is another indication of a problem with your Subaru turbo. If you ignore it, you could be making things worse. Here are some of the most common issues with this engine type:

If the faulty PCV valve is causing these problems, it may be time to replace the entire engine. This recall applies to certain models. The affected models are: 2013-2017 Subaru Impreza and WRX STI, 2017/2018 Subaru Crosstrek, and 2011-2012 Legacy. The problem is a result of weak piston ringlands and crankcase oil vapors entering the combustion chamber. A malfunction in either of these systems will lead to a reduced fuel/air octane ratio and engine failure. Drivers of WRX and STI models claim that this engine is completely useless and the internal parts overheat.

A misfiring turbocharged engine can be a sign of a bigger problem. This can be very expensive to fix. Another problem related to turbocharged engines is gasket oil leaks. Turbocharged engines are prone to these problems, and you should check the gaskets every 100,000 miles or so. It is best to get them checked at regular intervals to prevent the problem from getting worse.

When your Subaru is experiencing piston detonation, it may be a symptom of a faulty valve cover gasket. When this occurs, oil will leak into the engine, damaging the block. If you do not replace the valve cover gasket soon, your Subaru turbo engine may need to be repaired. In addition to replacing the gasket, you should also perform regular oil changes and replace coolant.

Besides clogged oil filters, your Subaru may also suffer from misfiring. If the oil supply line becomes blocked, the turbo may overheat. The other symptoms of a misfiring Subaru turbo engine are tight exhaust valve clearances, burnt valves, and more. Regardless of the problem, the symptoms are common and should be checked if you notice any of these. If these problems continue, your vehicle might need repair work.

Cracked piston rings can also cause a malfunctioning Subaru 2.4 turbo engine. These engines have three piston rings. Small cracks won’t cause any problems at first, but if they grow, they may cause the engine to lose one or more rings. Thankfully, Subaru made this problem easy to detect, and they extended their powertrain warranties to cover this problem. And now you can have peace of mind knowing your engine is back up and running.

Among Subaru’s many reliable options, a 2.4-liter turbo engine is known to be one of the most reliable. While it may have some problems, it offers low maintenance costs and a useful lifetime of 50,000 miles. That’s great news for Subaru owners. However, if you’re looking for the best turbo engine, you should consider a 2.4-liter model instead. It’s the best turbo engine you can buy, and its dependable service life makes it an attractive choice for many Subaru owners.


The turbo in a Subaru has a small oil filter, which can be clogged with matter over time. If you have not changed the oil in your Subaru for over six months, the turbo might have excessive oil consumption problems. The small filter is only effective to a certain degree, so if it becomes clogged with matter, it goes into bypass mode and will restrict oil flow to the engine. In this case, excessive wear and tear will occur.

Other possible causes of Subaru 2.4 turbo engine problems include vacuum leaks, burnt valves, and faulty ringlands. The valves can also become tight as a result of heat cycles. It’s important to remember that the Subaru 2.4 turbo engine is designed to last for more than 50,000 miles, so you’ll want to keep it serviced regularly. If you don’t care about the problem, it will only get worse.

Some common symptoms of a turbo problem include misfiring, a loss of compression, and smoke coming from the exhaust. If you notice these symptoms, you’ll need to change the oil. A leaking turbo is the most common cause of a Subaru 2.4l engine problem. You should change the oil and filter according to the manufacturer’s recommendations, but be sure to follow the owner’s manual.

A faulty Subaru 2.4 turbo engine can be caused by many factors, including engine mileage, a defective crankshaft, or a faulty fuel pump. Even if you drive an older car with many years of service, you should consider a new car if you suspect an engine problem. It’s important to get your car repaired before it becomes too expensive. You don’t want to drive your Subaru to the mechanic and have a faulty engine.

Another common issue is oil starvation. If you suspect oil starvation, change the gasket right away. It’s not uncommon for these valve cover gaskets to leak oil. Subaru turbo vehicles with more than 100,000 miles may need a valve cover gasket replacement. If you notice these symptoms, check the gasket and oil filter before you purchase a new car. If you see smoke coming from the engine, you’ve got a problem with your turbo.

Generally, Subaru 2.4 turbo engines are reliable and produce adequate torque and horsepower. As long as you don’t drive your Subaru 2.4 turbo engine very often, the engine should still be serviced in order to prevent more expensive problems. If you experience any of these symptoms, your vehicle may need a replacement engine. A replacement engine can cost anywhere from eight to a dozen thousand dollars. If you have a newer Subaru, consider looking into getting an engine repair instead.

Other causes of Subaru 2.4 turbo engine problems include ringlands. These ringlands can crack or break while removing the engine. Minor cracks won’t affect the performance of your Subaru, but large cracks can ruin the cylinder walls. However, cracks on ringlands are difficult to detect without dismantling the engine. Cracks can cause severe problems if left unchecked.


If you’ve noticed an erratic misfire, the turbo in your Subaru is likely to need replacement. Several possible reasons for a misfire include vacuum or boost leaks, faulty pistons, burnt valves, and exhaust valve clearances that are too tight. If you’ve noticed any of these symptoms, it’s time to bring your car in for a diagnostic. If you ignore the misfire, it could grow into a larger problem.

Overheating is another common problem with turbos, so a proper oil change is essential for your engine to stay healthy. Overheating can lead to a variety of problems, including oil starvation. The resulting black smoke and white smoke may signal the need for a repair. For the most part, these problems can be resolved with a quick visit to your local Subaru service center. However, it may be necessary to make a costly repair to your Subaru if the problem persists for more than a few months.

Other common problems associated with the Subaru 2.4 turbo engine include excessive oil consumption, improper lubrication, and defective piston rings. It is important to regularly check the oil supply bolts and replace the oil filter according to the manufacturer’s recommended interval. Proper lubrication prevents premature wear and tear on the engine. Additionally, problems with ignition and combustion can result from defective piston rings. For a proper Subaru service center, regular oil changes will be necessary.

While you’re looking for a quality repair shop, you should first consider the type of Subaru 2.4 turbo engine your vehicle has. There are several types of problems, but the most common ones are:

The Subaru 2.4 turbo engine has a limited number of models, which means the parts and labor can be expensive. Subarus have lower demand than some of their competition, so repairs will cost more. The more popular cars, such as Mercedes-Benz and BMW, have a larger lineup of models, so parts may be harder to find. However, Subarus are still more expensive than many rivals. For this reason, you may want to consider buying an extended warranty solution.

Another issue that affects the Subaru 2.4 turbo engine is a leaking valve cover gasket. This can cause a visible leak or a smell of burning oil. If you notice any of these problems, it’s time to replace the valve cover gasket. If you can afford it, you may have a lot to gain. There are several reasons why you should replace the gasket. If you’re not sure what to do, call a Subaru repair specialist.

A faulty PCV valve can cause your Subaru’s engine to stop running and even stall. The faulty PCV valve will also let crankcase oil vapors reach the combustion chamber. This can cause a weakened piston, increased crankcase pressure, and more. Consequently, your car might suddenly lose power, or the engine could even fail. If your Subaru 2.4 turbo engine has all these problems, consider getting a new car.
