What is wrong with your turbocharger?

If a turbocharger is malfunctioning, it could be due to several issues such as worn bearings, oil leaks, or damage to the turbine or compressor blades. Symptoms may include loss of power, excessive exhaust smoke, or unusual noises. Additionally, problems with the engine's air intake or exhaust systems can also affect turbocharger performance. It's essential to diagnose the specific issue to determine the appropriate repair or replacement.
