How Long Do Valve Cover Gaskets Last

If you own a car, chances are you’ve had to replace a valve cover gasket at some point. But how often should you be doing this? And how long do valve cover gaskets actually last? In this blog post, we’ll explore the answer to both of these questions. We’ll also provide some tips on how to prolong the life of your valve cover gaskets and avoid having to replace them too frequently.

What is a valve cover gasket?

A valve cover gasket is a seal located between the cylinder head and the valve cover. The gasket prevents oil from leaking out of the engine and keeps dirt and debris from getting into the engine. The gasket is made of either rubber or silicone and is usually replaced when the engine is serviced.

How long do valve cover gaskets last?

The average valve cover gasket will last anywhere from 30,000 to 60,000 miles. However, there are a number of factors that can affect the lifespan of a valve cover gasket, including the type of engine oil used, the type of gasket material, and the driving conditions.

What causes valve cover gaskets to fail prematurely?

Valve cover gaskets can fail prematurely for a number of reasons. One common cause is improper installation. If the gasket is not installed correctly, it can become damaged and start to leak. Another common cause of premature failure is engine oil leaks. If oil leaks onto the gasket, it can break down the material and cause it to fail. Finally, excessive heat from the engine can also cause the gasket to degrade over time and eventually fail.

How to prevent valve cover gasket failure

The valve cover gasket is a crucial part of your car’s engine, and it needs to be in good condition in order to keep your engine running properly. There are a few things you can do to prevent valve cover gasket failure, and these tips will help you keep your gasket in good condition for longer.

1. Check your oil level regularly and change your oil when necessary. Dirty oil can cause the valve cover gasket to deteriorate, so it’s important to keep your oil clean.

2. Avoid over-tightening the bolts on the valve cover. This can cause the gasket to compress too much and eventually fail.

3. Inspect the valve cover gasket regularly for signs of wear or damage. If you see any tears or cracks, replace the gasket as soon as possible.

4. If you’re doing any work on the engine that requires removal of the valve cover, be careful not to damage the gasket when reinstalling it.

By following these tips, you can help prevent valve cover gasket failure and keep your engine running smoothly for longer.


On average, valve cover gaskets will last between 30,000 and 50,000 miles. However, there are a number of factors that can affect their lifespan, including the type of engine oil you use and how often you change it. If you take good care of your engine and regularly change your oil, you can expect your valve cover gaskets to last for many years.
