What are the symptoms of a faulty diesel turbocharger?

[BradleyFitz]

Diesel turbocharger damage symptoms are as follows: 1. Reduced power: A faulty diesel turbocharger will cause a significant decrease in engine power with no boosting effect. 2. Abnormal noises: Prolonged engine operation with poor exhaust heat dissipation will produce sharp, piercing sounds during operation, and also prevent sufficient air from entering the combustion chamber, resulting in power loss. 3. Black smoke emission: After turbocharger damage, insufficient air enters the combustion chamber, causing a 30% power drop. Increasing throttle doesn't boost power but only emits black smoke. 4. Poor oil return: During use, if the lubricating oil return line becomes deformed or blocked, causing poor oil return, the lubricating oil pressure in the intermediate body becomes too high, forcing compressed lubricating oil to flow along the rotor axis to both ends and squeeze out the sealing rings, resulting in oil leakage.
