Will the oil leakage from the valve cover of mercedes benz c cause the spark plug to be flooded？

Mercedes benz c valve cover oil leakage flooded the spark plug mainly includes:

firstAging of valve cover gasket, resulting in poor sealing, resulting in valve cover gasket oil leakage. This is usually because the vehicle has been used for a long time, and the valve cover gasket material is gradually worn and hardened, which can not be effectively sealed, resulting in oil leakage.

nextThe positive crankcase ventilation valve is blocked, causing the crankcase pressure to rise, thus releasing pressure from the valve cover gasket or other weak places, resulting in oil leakage. This situation usually occurs after the vehicle runs for a long time, and a large amount of dirt accumulates inside the ventilation valve, which leads to its failure to work normally.

In addition, the oil leakage from the valve cover may also affect the spark plug, because the oil may flow into the combustion chamber and flood the spark plug. Spark plug is an important component of the ignition system of gasoline engine. Its function is to introduce high-voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thus igniting the combustible mixture in the cylinder. It mainly consists of a connecting nut, an insulator, a connecting screw, a center electrode, a side electrode and a shell, wherein the side electrode is welded on the shell.

To sum up, the main reasons why the spark plug was flooded by the oil leakage from the valve cover in mercedes benz c were the aging of the valve cover gasket and the blockage of the crankcase forced ventilation valve.
