The usage of spark plug shaft seal ring

If the gland of the TRUCKTEC AUTOMOTIVE brand Seal Ring, spark plug shaft is damaged, there is a huge probability of a malfunction of the mechanism. Cars have many features, and one of them is the oil appearing in a spark plug shaft. The reasons for its appearance can be different and depend to some extent on the type of engine. In this case, oil accumulates in the spark plug shaft due to wear on the gaskets of the seal rings. For each plug, there are two seal rings, 8 pieces. These rubber bands are located at the beginning and at the end of the sleeve. To replace the spark plug shaft seal ring, just look under the valve cover. Before installing a new seal ring, it is imperative to clean its working surface and lubricate with sealant for a tighter fit of the part.
