- In the intricate machinery of an internal combustion engine, the valve cover gasket and its accompanying bolts play a crucial, albeit often overlooked, role. These seemingly insignificant components are the guardians of engine integrity, ensuring optimal performance and longevity.
- Spring Back: The rubber-covered OD of the seal may have elastic memory, causing it to retract from the installation point after being pressed in. Ensuring the bore is clean and provides sufficient friction helps prevent spring back.

One of the key benefits of floating oil seals is their ability to provide a secure and reliable seal even in high-pressure environments. Unlike traditional seals that rely on compression to create a seal, floating oil seals utilize a unique design that allows them to float on the oil and adjust their position as needed to maintain an effective seal. This design not only enhances the reliability of the seal but also helps to prolong the lifespan of the seal by reducing wear and tear.
Always start by making sure the oil seal is facing the right direction. The oil seal must be positioned with its spring to the side of the medium to be sealed. The oil seal must then be pressed into the bore. It must fit tightly (H8 in the groove is recommended). Use appropriate tools for this, such as an impact socket set, to ensure that the force is applied evenly during pressing. The oil seal must never be hammered into the bore with brute force, but eased in.


Many seals come with a garter spring, found within the backside of the seal. It provides contracting pressure against the sealing surface. Making sure the spring seats correctly within the seal is an excellent first step.
