What causes a turbo charger to go bad?
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.
What causes oil to leak from a turbocharger?
When a turbocharger is installed correctly, it should NOT leak oil, however, there can be cases where oil leaks occur. The following highlights some of the main causes and signs of oil leaks. The above diagram shows the correct oil pressure in both housings resulting in no leaks from the turbo.
What are the causes of damage to a turbocharger?
There are several main causes of turbocharger damage: To work effectively, a turbo needs a constant flow of clean oil, and to keep your turbo in top condition, you need to ensure that you change the oil and oil filter regularly.
Why is my Turbo not working in my car?
Quite often, a turbocharger failure is a symptom of an underlying engine problem that will need to be addressed before simply replacing the turbo unit, or it will repeat itself. Here are some more symptoms and their possible causes: If a turbocharger doesn’t produce enough boost pressure, it won’t work.
What to do if your Turbo starts to leak?
Ok, back to the topic of the leaky turbocharger. If your turbo has been fine for years and it starts to leak. You need to look at a few things. First off check shaft play. There is always a little side to side. But, it shouldn’t touch the compressor housing. Next check the in and out play. You really shouldn’t feel much at all.

What are the signs of a leaking turbocharger?
The signs of a leaking turbocharger system start with a lack of power or random misfires. In some cases, the escaping boost pressure can be heard. But, if the wastegate or bypass valves are leaking, you might not hear any noise. If you get a vehicle in that is not generating enough boost, don’t automatically assume it is the turbocharger.
What to do if you have a turbo leak?
All turbocharged engines need a way to control the pressure in the intake manifold. The pressure can be managed on the exhaust side with a wastegate, or on the compressor side using a diverter valve. One of the most leak-prone components is the boost diverter/bypass control valve on the compressor turbine.
When do I need to replace my turbocharger?
As with any other car component, everything has a life span and the turbocharger is no exception. If you have driven over 100,000 miles on the factory turbo and suffering turbo problems, it probably needs replacing. Poor Oil Quality Forming Carbon Deposits.
