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.
People also ask, how do you stop a turbo from failing?
- Regular maintenance. It is important that the vehicle is serviced on time and on a regular basis.
- Timely oil changes. The engine oil must be changed correctly and on time.
- Use of correct and good quality engine oil. The engine oil must of course meet the prescribed quality.
- Gentle startup.
Furthermore, how long do turbos usually last? Turbos are designed to last the lifetime of the vehicle (or around 150,000 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.
Another frequent question is, what happens when a turbo fails? Be aware that when your turbo fails the pieces will drop down into the intercooler and the oil seals will fail. Unfortunately the engine can actually run on this oil and can run away at maximum RPM until all the oil is used up, at which point the engine will seize.
Likewise, can a turbo suddenly fail? Turbochargers are built to last the lifetime of a vehicle. Car manufacturers extensively test the uniquely matched turbocharger and engine together, to avoid any unexpected failures. However, lack of maintenance, hazardous driving or a single component failure, could have a harmful influence on your turbocharger.
- The car has noticeable power loss.
- The acceleration of the car seems slow and noisy.
- The car doesn’t easily maintain high speeds.
- There is smoke coming from the exhaust.
- There is an engine fault light on the dashboard.
