What is the cause of air leakage in turbocharged exhaust manifold?

The following is a detailed introduction to the causes of turbocharging air leakage: 1, oil seal ring aging: parts aging is inevitable after years of driving. If the aging of the oil seal ring will lead to oil leakage in the car, replace the sealing ring. 2. Poor lubrication: If the lubrication in the supercharger is poor, it is easy to cause friction between parts, resulting in parts wear and oil leakage, so it is necessary to refuel or replace worn parts. 3. Supercharger damage: The automobile supercharger is damaged due to a collision accident, and there will be oil leakage. In this case, the supercharger should be replaced directly.
