What are the symptoms of a broken supercharger?

[VanSamuel]

Turbine supercharger's condition will affect fuel economy, engine output power, and engine emissions. The following are the symptoms of a broken supercharger: 1. Poor sealing of the turbine supercharger impeller shaft: Blue smoke from the exhaust at idle, sometimes light and sometimes heavy. No blue smoke while driving, but engine oil is consumed. 2. Severe blockage of the exhaust gas recirculation pipe: Blue smoke from the exhaust at idle and while driving, worse when accelerating, with significant engine oil consumption. 3. Abnormal noise: The engine makes abnormal noises while driving, and the exhaust pipe emits a lot of blue smoke. This is caused by wear or aging of piston rings, cylinder walls, or valve oil seals;
