What are the symptoms of a faulty engine turbocharger?

[Ariana]

Symptoms of a faulty engine turbocharger include: decreased vehicle power, incomplete fuel combustion, severe carbon buildup in the engine, increased fuel consumption, burning engine oil, blue or black smoke from the exhaust pipe, engine shaking, and a screeching sound during rapid acceleration. The reasons for these symptoms are: 1. Blue smoke during driving or idling is due to poor sealing of the turbocharger impeller shaft. 2. Increased fuel consumption or higher engine oil consumption is caused by severe blockage of the engine's exhaust gas recirculation pipe. 3. Abnormal engine noise during driving accompanied by significant blue smoke from the exhaust pipe is due to wear or aging of piston rings, cylinder walls, or valve oil seals. 4. Abnormal noise during acceleration and deceleration is caused by a rupture in the turbocharger air duct.
