What are the symptoms of a broken engine turbocharger?

[VonTheo]

Symptoms of a broken engine turbocharger: The car's exhaust pipe emits blue or white smoke, decreased power, increased fuel consumption, increased engine oil, and unstable turbo pressure. When the car is idling, the exhaust pipe emits blue or white smoke due to poor sealing of the turbocharger impeller shaft. When the turbocharger malfunctions, the car's power will noticeably decrease, and fuel consumption will rise accordingly. If the exhaust gas recirculation pipe is blocked, stepping on the accelerator will not only produce blue smoke but also accelerate engine oil consumption. It is important to note that after starting the engine, you should not drive immediately. Instead, let the engine idle for 2 to 3 minutes to allow the turbocharger to be fully lubricated before driving. During long-distance driving, if the engine has been running at high speed for an extended period, do not turn it off immediately. Sudden shutdown can cause the residual oil in the turbocharger to overheat and damage the bearings.
