How to Identify Turbocharger Failure?

[FinleyAnn]

Methods to identify turbocharger failure: 1. Oil leakage: Significant increase in oil consumption, blue or black smoke from exhaust, and reduced power; 2. Metal friction noise: Black smoke from exhaust pipe, power loss, and abnormal noise from turbocharger; 3. Bearing damage: Turbocharger bearing failure, engine power loss, high oil consumption with black smoke, and in severe cases, turbocharger ceases to function. Causes of turbocharger failure: 1. Insufficient lubricating oil pressure and flow; 2. Debris or sediment entering the lubrication system, causing oil oxidation and deterioration; 3. Metal friction noise occurs when the turbocharger rotor bearings or thrust bearings are excessively worn, causing the impeller to rub against the turbocharger housing; 4. Blocked turbocharger oil lines, leading to excessive oil accumulation at the intermediate support of the rotor assembly, which then flows along the rotor shaft into the compressor impeller; 5. Damage to the sealing ring or oil slinger near the compressor impeller, allowing oil to enter the impeller chamber and subsequently flow into the combustion chamber along with the pressurized air through the intake pipe.
