What are the symptoms of a failed turbocharger in large vehicles?

[DelJayden]

The symptoms of a failed turbocharger in large vehicles are as follows: Engine Power: Black smoke from the exhaust pipe, burning engine oil, and low oil level. If the sealing ring is damaged, exhaust gases can enter the engine lubrication system through the sealing ring, contaminating the oil and rapidly increasing the crankcase pressure. Additionally, during low-speed engine operation, oil may escape through the sealing ring into the exhaust pipe or enter the combustion chamber to burn, leading to excessive oil consumption and the occurrence of "oil burning." Poor Exhaust Heat Dissipation: Prolonged engine operation can result in poor exhaust heat dissipation. When the engine is running, a sharp, screeching noise may occur, preventing sufficient air from entering the combustion chamber, which leads to reduced power and insufficient engine performance.
