- Another important function of the c15 valve cover gasket is to maintain proper compression in the engine. The gasket helps to seal the combustion chambers, ensuring that the engine can generate maximum power and efficiency. If the valve cover gasket were to fail, it could lead to a loss of compression in the engine, resulting in decreased performance and fuel efficiency.
Oil seals are commonly used in engines, gearboxes, and other rotating machinery to prevent the leakage of oil from shafts and bearings. They are typically made from rubber or elastomeric materials that are resistant to oil and heat. The seal is installed in a housing or bore that is larger than the shaft, and it is pressed against the shaft to create a tight seal.

Different Types of Oil Seals
Polyacrylate oil seals are a perfect compromise between quality and cost. They perform well with high temperatures and chemicals, but not as well as Viton oil seals. Polyacrylate has a temperature range of -25 degrees Fahrenheit to 300 degrees Fahrenheit. Due to their outstanding resistance to hot oil and oxidation, they are commonly used in automobile transmissions and hoses; however, they are also used for shaft seals, gaskets, and o-rings.
Before installing the oil seal, it is essential that the oil seal, shaft and bore are not damaged. So, ensure that the surfaces the oil seal comes in contact with do not have any sharp points or burrs. The sealing lip is fragile, so any minor damage to it can cause leakage. Also, make sure the oil seal is clean. Even a small amount of dirt can cause a leak. Therefore, never use a pre-used oil seal for the assembly.
Maintenance and Replacement of Oil Seals


The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
