What is a valve cover gasket?

Like all seals in your vehicle, the valve cover gasket's main job is to provide a watertight seal. Over time, it can become damaged, causing oil leaks. This problem needs to be addressed quickly if you don't want to end up with more serious consequences.

What is a valve cover gasket?

The valve cover gasket is a rubber or silicone part that, as the name suggests, connects the valve cover to the cylinder head. It prevents oil from leaking out of the engine and maintains the pressure needed to lubricate the various parts of the valve train. Therefore, this gasket is essential to prevent leaks in the engine block. A faulty gasket can lead to oil leaks, reduced engine performance, and in some cases, serious damage to the engine itself.

Types of valve cover gasket

There are several types of valve cover gaskets made from different materials:

  • The cork gasket, which is no longer used today;
  • Paper gaskets;
  • Rubber seals;
  • The elastomer gasket found on most vehicles.

Symptoms of a worn valve cover gasket

If you notice any of the following symptoms, the valve cover gasket may be worn:

  • The valve cover is leaking engine oil.
  • The valve cover gasket is dry and cracked.
  • Engine oil level is abnormally low
  • The engine light is on.

What are the consequences of continuing to ride with a leaking valve cover gasket?

If you're experiencing this problem, there's no doubt that your valve cover gasket is damaged. A visual inspection will reveal this. This is a serious problem that needs to be fixed as soon as possible. When oil leaks, the engine and its parts are no longer properly lubricated. This can lead to premature wear or even breakage in extreme cases. We strongly recommend that you do not continue riding if you notice a leak in your valve cover gasket.

What to do if your valve cover gasket is leaking?

The first thing to do if your valve cover is leaking is to stop riding. Failure to do so could result in a more serious failure that could bring your vehicle to a stop. If the valve cover gasket is the cause of the problem, he can make the necessary repairs.

A leaking valve cover gasket affects engine and vehicle operation. To avoid serious breakdowns, we advise you to be very careful with this part and check it from time to time.

Importance of replacing the valve cover gasket

Replacing the valve cover gasket is critical to maintaining optimum engine performance. Oil leakage from a defective gasket can result in inadequate lubrication of engine components, causing premature wear and costly damage. In addition, oil leaks can contaminate other engine parts, causing further problems.

When should I replace the valve cover gasket?

The valve cover gasket is a wearing part and should be replaced after 100,000 km. However, the gasket can be damaged before 100,000 km: if the gasket wears, dries out and cracks, it will cause engine oil leaks. The engine oil level will drop and engine parts will not be properly lubricated. If the valve cover gasket isn't replaced in time, other engine parts may wear out and cost much more to replace.
