Internal engine components are lubricated with oil. Engines have many seals and gaskets that prevent oil from leaking out of the engine. The valve cover gasket is located on the top of the engine. It prevents oil from leaking onto the hot exhaust system, which could cause a fire.
Gaskets deteriorate over time, allowing engine oil to leak. An oil leak can not only cause a fire but also can drain your engine of oil, which can cause serious engine damage.
To replace the valve cover gasket, the technician removes the bolts securing the valve cover to the engine. S/He removes and cleans the valve cover, and then replaces it.

What to watch out for
Components such as spark plug tube seals and grommets can also leak oil, which can be mistaken for a leaking valve cover gasket. These seals and valve cover gasket should always be replaced together.
Recommendations
Using high-quality valve cover gaskets will reduce the chance of recurring leaks and additional repairs.
Why this happens
Valve cover gaskets need to be replaced when they begin to leak oil, which can damage other engine components, especially belts and hoses.
Oil leaking from valve cover gaskets can result in a burning smell coming from under the hood.
When replacing the valve cover gasket, we recommend having a valve adjustment performed, if applicable. Doing so will save labor costs.
