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.
