Valve cover gasket is used as a seal between the valve cover and the cylinder head. When the valve cover gasket has been used for a long time and under high temperature, it may begin to fail. It will cause oil leaks down from the sides of the cylinder head.
When you first notice that the valve cover gasket has some problems (burning oil smell, low engine oil level, dirty valve cover…etc.), it is time to change the gasket.
What are the most common materials for valve cover gaskets? There are 5 main types of rubber that are commonly used to manufacture valve cover gasket, their chemical properties tend to endure oil and high temperature.
