- Moreover, a worn or damaged valve cover gasket can allow dust and debris to enter the engine, wreaking havoc on sensitive components
4.6 valve cover gasket. It can also lead to a loss of oil, necessitating more frequent top-ups and potentially causing engine overheating due to inadequate lubrication.
- The top valve cover gasket serves as a protective barrier between the valve cover and the engine's cylinder head. Its primary function is to seal the area around the valves, preventing oil from leaking out and keeping contaminants from entering the engine. A failure in this small but mighty gasket can lead to a myriad of problems, including oil leaks that not only damage other engine parts but also pose environmental concerns.
14.2 Oil-Seal Requirements
Additionally, lubricants can be used on both sides of the oil seal to reduce friction and enhance sealing performance. The sealing process is crucial for preventing contaminants from entering machinery or equipment while keeping essential fluids contained within.

6. Proper installation is key to effective oil seal performance.


Why use NOK-CN factory-made oil seals?
Oil seal installation

Gaskets and oil seals should be replaced if worn or leaking, or whenever removed during servicing. Replacement is simple, but some engine dismantling may be necessary to reach them. Buy gasket sets from a dealer for the make of car, and state clearly for what parts they are needed.
6. AMOUNT OF LUBRICANT: Seals perform better when lubricated but some machines will go through some dry spells. When this occurs using a leather or PTFE seal will be more beneficial as those type of seals can operate with less lubrication.
