- The valve cover gasket seals the junction between the cylinder head and the valve cover, preventing oil from entering the exhaust system where it can burn off, potentially causing emissions issues. Over time, this gasket can deteriorate due to heat, age, or physical damage, leading to oil leaks that can compromise engine performance and cleanliness.
4) Allowable total eccentricity
The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.

Oil seal material
However, rubber-cased seals do have limitations. For example, during installation, shear stresses can build up between the seal and housing wall, causing the seal to release itself.
