What Causes a Valve Cover Gasket to Fail?

Valve cover gaskets can fail for a number of reasons. The most common reason is simply age and wear. Over time, the gasket will become hard and brittle, and eventually, it will crack or break.

This can happen even if the gasket is never removed; just the vibration of the engine over time can cause it to fail. Another common cause of valve cover gasket failure is an improper installation. If the gasket is not installed correctly, it may not seal properly and will eventually leak oil.

This can be caused by either using an old or damaged gasket or by not installing the gasket correctly in the first place. Finally, some valve cover gaskets are simply made from inferior materials that are not up to the task of sealing the engine against oil leaks.

If you suspect your valve cover gasket has failed, it’s important to have it replaced as soon as possible to avoid any further damage to your engine.

Gasket Reuse vs New Gaskets


If you have a blown head gasket, it is important to know if you can reuse valve cover gaskets. The answer is yes, but there are a few things to keep in mind. First, make sure that the old gaskets are not warped or damaged.

If they are, it is best to replace them. Second, clean the surfaces of the valve cover and the engine block where the gaskets will be installed. A wire brush can be used to remove any debris or build-up on the surfaces.

Finally, apply a thin layer of sealant to both sides of the new gaskets before installing them. This will help ensure a tight seal and prevent leaks.
