- The 6.0% 20Valve Cover Gasket, often referred to as the 20 Valve Gasket, is a critical component in the engine of many modern vehicles, particularly those equipped with V8 engines. This gasket plays a vital role in maintaining the proper seal between the valve cover and the engine block, ensuring that oil, coolant, and other essential fluids do not leak out.
What materials are available?
Rubber materials, operational temperature ranges and their compatibility with fluids
If the manifolds have been removed, refit them with new gaskets (See Exhaust manifold gasket replacement ).
Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.
