This can cause abrasive damage to the inside of the turbo. It's important that the engine oil and oil filter are both replaced at the manufacturer's recommended intervals.
If the seals between the compressor and the engine become worn or cracked, oil will leak into the exhaust system. As a result, the turbo has to work harder to increase air pressure.
This problem is also known as over-speeding. Ultimately, it will reduce the efficiency and the boost delivered by the turbo. A turbocharger is essentially made of two fundamental components: the compressor at the front and the turbine at the back.
Sometimes, foreign objects such as dust particles, dirt, leaves and small stones can enter the turbo, either via the compressor inlet or turbine inlet. If the foreign object enters the compressor housing, it often comes from the air filter. In contrast, if the foreign object causes damage to the turbine, the problem usually originates from the engine itself. The efficiency of the turbo will be reduced if foreign objects start to damage the compressor wheels or turbine blades.
To prevent this happening, your air filter should be serviced and replaced regularly. You should also check your turbo for debris. Turbos are designed to last the lifetime of the vehicle or around , miles ; however, it's possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo. Yes, you'll still be able to drive your car if your turbocharger fails; however, engine failure won't be far behind, so only drive on if you have to.
As soon as you spot any of the turbo failure symptoms outlined above, you should get your turbo checked as soon as possible by a qualified technician. The longer you leave it, the worse and more expensive the problem will get. At Dowleys Garage, we can run a diagnostic check to identify the problem and advise on any necessary repairs. The use of oil provides lubrication that prevents the car's part from friction and getting destroyed.
The engine's turbocharger is made up of different moving parts that get in touch with each other continuously and at high speeds. Like any car's internal components, the turbocharger doesn't not only require a specific amount of oil continuously, and it also requires a specific grade or oil type to continue performing properly. The turbocharger gets its oil from the engine. When there is not enough oil in the turbocharger, contaminants could build-up, causing oil contamination and, therefore, causing complete damages to the turbocharger.
Over time of use, the seals between the engine and the compressor can get worn and cause internal damages. These damages allow the oil to leak into the combustion system. When there is too much oil in the combustion system, the turbo has to work harder and push more air into the combustion system to burn this oil. When the turbo works harder than it should, it can lose its efficiency over time. This specific problem is known as over-speeding.
When the turbo is overspeeding, it has to rotate at a higher speed than it was designed for at specific applications. Thus, the BTN turbo will start tearing and wearing resulting in complete turbo damage in a short period. There are two ways for strange objects to enter the turbo: via the compressor hose in the front, or via the turbine in the back. Whatever the source or location where the objects enter, having strange objects in the turbo can result in major damages to the turbo and the entire engine.
Once strange objects start to build up inside the turbo, you will start noticing a reduction in the car's power if not major turbo problems. The best way to prevent this problem from happening is to perform regular cleaning up to the air inside the turbo. As we mentioned before, turbos are very reliable and don't get damaged very often.
In general, turbos can last up to , miles without any problem. However, this number might change depending on your driving style. For instance, if you drive your car very hard, expect that your car's turbo can get damaged sooner. Yes, you can drive your car if there are symptoms of the bad turbo; however, the longer you wait on the problem, the higher the potential that your engine will fail very soon.
Therefore, you must drive your car only if you need to, and you must take your car to the closest mechanic as soon as possible. Some people might think they don't have the time to put their car in a mechanic shop to get their turbo repaired. What they don't know is that ignoring such a problem can lead them to put their car in the garage forever unless they replace the entire engine. Loss of power and slow acceleration — the turbocharger is designed to make your car reach top speeds faster.
Smokey exhaust and excessive emissions — one of the problems with worn seals and cracks in the turbo is that this allows oil to enter the exhaust, which will burn off with a very distinct greyish blue smoke. Check engine light — there are several reasons why this light can become illuminated on your dashboard.
It could be down to problems with your sensors, or even a loose petrol cap, but sometimes it may indicate a serious issue with your turbo.
Stay on the safe side and get the car checked out by a mechanic. Any drop in boost should indicate to you to book a visit to the service centre for an inspection. Burning oil — as we mentioned, oil leaking in the turbocharger is a sign of gradual failure. Disconnect the downpipe at the front of the turbo and take a look inside. Can you see oil? Any sign of deposits in the pipe means that you need to get the turbo serviced.
If this problem is left unchecked the entire system could fail. If this is combined with any of the other signs listed here, then you can be sure of issues with the part. Believe it or not, you can drive on without the turbo, but it is probably safer to call for a recovery lift. Should you decide to drive with a broken turbo, then first unhook the linkage from the wastegate activator, and then use a wire to hold it open as you drive the necessary distance to get to a mechanics.
