What are the symptoms of turbocharger damage?

[StCorbin]

Symptoms of a faulty turbocharger: 1. The car emits blue smoke during driving or idling, which is caused by poor sealing of the turbocharger impeller shaft; 2. Increased fuel consumption or higher engine oil consumption, which is due to severe blockage of the engine's exhaust gas recirculation pipe; 3. The engine makes abnormal noises during driving, and the exhaust pipe emits a large amount of blue smoke, which is caused by wear or aging of piston rings, cylinder walls, or valve oil seals; 4. The car makes abnormal noises when accelerating or decelerating, which is caused by a rupture in the turbocharger air duct.
