Valve Cover Gasket Function

The valve cover gasket is an important part of your car’s fuel system that goes over the top portion of the engine cylinder head. This gasket prevents any oil or fuel from leaking out of the engine as it travels around the camshafts, rockers, and valves. The cover gasket is also in charge of sealing off numerous spark plug ports to keep them protected and prevent spark plug fluid leaks.

Types of Cover Gaskets

In the majority of modern cars on the market today, there are two main types of cover gaskets that you will find in cars – either liquid gaskets or formed rubber gaskets. The type of gasket you have in your vehicle is determined by the type of material used in the formation of the valve cover gasket and how much pressure it puts on the seal it covers.

The valve cover keeps the gasket compressed, which prevents leaks, being the cover gasket’s overall job in the car. Over time, however, the gasket can become faulty and damaged due to the high amount of engine heat or the bolts loosening over time, causing the gasket to become brittle and cause an engine oil leak.
