638742 - Valve Cover Gasket & Aftermarket Parts

The valve cover gasket is a key component in an internal combustion engine. It is located between the valve cover and the cylinder head, sealing the space where the cover is bolted to the engine. Its main function is to prevent oil leaks from the top of the engine, where the camshaft and valve components are located, ensuring that oil stays inside the engine and doesn’t leak out, which could cause damage.

The gasket is typically made of rubber, cork, or a composite material, and is designed to withstand high temperatures and the pressures within the engine. Over time, it may degrade due to exposure to heat and oil, resulting in leaks that could cause engine oil loss, leading to low oil levels and potential engine damage.

Here are the primary functions and features of a valve cover gasket:

1. Oil Sealing: Prevents oil from leaking out of the engine, which could result in contamination and engine failure.
2. Engine Cleanliness: Keeps contaminants, such as dirt and debris, from entering the engine through the valve cover area.
3. Durability: Designed to withstand high engine temperatures and pressure without losing its sealing capabilities.

Valve cover gaskets need to be replaced when they start leaking, which often manifests as oil stains around the valve cover area. Regular maintenance and inspection can help in identifying early signs of gasket wear and ensure the engine operates smoothly.
