Influence of valve seat ring damage;

1. After the valve seat ring leaks oil, it will flow down the cylinder head. Due to the high temperature when the engine is working, the engine oil attached to the engine surface will slowly evaporate, producing pungent smoke.

2. The air tightness of the engine will be affected, and the working pressure of the engine will also leak from the oil leakage. The engine has an exhaust gas recirculation valve connected to the throttle valve, and air leakage will affect the stability of the engine.
