Why does turbo make a sound

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.

As many fans of a turbocharged engine will know, a turbo often makes a whistling sound. But what if there is a change in the noise a turbo makes? If your turbo starts to make a noise similar to an emergency services siren, or a dentist drill, it is a sure sign that there may be a problem.

That said, if you're still running a bushed turbo on a performance car - maybe it's time to upgrade anyway! To explain the difference between bush also known as sleeve or journal bearing and ball bearing turbos, check the images below. Note: We accidentally say "Blow off valve" during the video at one point when meaning "Throttle body" closing, this is obviously an error. A blow off valve helps alleviate the pressure in the intake during closed throttle surge, "blowing off" excess boost.

Note 2: We touch on the difference between open and closed throttle flutter. As an additional bit of information here, it was pointed out to me that closed throttle flutter is actually known as "reversion", whereas open throttle flutter is more accurately called "compressor surge".

Both are technically compressor surge, and both sound essentially the same, however the different conditions under which they occur are important to identify. View 4 images.
