Common faults of turbocharging: 1. Turbocharger oil leakage fault. The oil consumption is large, but the exhaust smoke is normal, and the power is not reduced. It is generally caused by oil leakage. 2. The engine oil consumption is high, and the exhaust emits blue smoke, but the power does not drop. Because of the oil leakage at the compressor end of the supercharger, the oil enters the combustion chamber through the engine intake pipe and is burned. 3. Large oil consumption, blue smoke or black smoke from exhaust, and reduced power. The clearance between the piston and the cylinder is excessively worn, and the engine oil enters the combustion chamber and is burnt. 4. The turbocharger has metal friction sound. The exhaust emits black smoke, the power decreases, and the supercharger makes abnormal noise. It may be caused by excessive wear of turbocharger rotor bearing or thrust bearing and friction between impeller and turbocharger housing.
