Summary

The valve cover gasket acts as a tight seal that prevents oil from leaking into other parts of the engine.
The valve cover gasket is typically seated on the valve cover, so once you find the valve cover, you’ll find the gasket too. On most vehicles, you can usually find the valve cover in between the engine block and cylinder head.
To access the valve cover gasket, you’ll have to remove everything in the way first. On some vehicles, this includes the PSV hoses, spark plug brackets, and a bunch of other wires.

Q: Where is the Valve Cover Gasket Typically Located?

A: The valve cover (aka “rocker arm cover”) gasket is typically made of plastic, rubber, or cork, and is a seal that prevents oil from leaking out of the engine. The oil inside the valve cover is splash oil; it’s not under pressure, but the oil will still leak in a big way if the valve cover gasket is compromised.

With the valve cover gasket removed (sometimes you have to remove the intake manifold first for access), you can see the valve springs and rockers on pushrod (OHV) engines and you’ll see the camshaft(s) on overhead cam (OHC) engines.
