What Is a Valve Cover Gasket?
The valve cover gasket is a rubber, silicone, or composite seal that sits between the valve cover and the cylinder head. Its job is to keep engine oil contained while allowing access to internal valve train components.
Over time, exposure to heat cycles causes the gasket to:
- Harden
- Shrink
- Crack
- Lose elasticity
Once this happens, oil begins to seep or leak from the top of the engine.
When to Replace a Valve Cover Gasket
Drivers often ask when to replace valve cover gasket or do you need to replace valve cover gasket.
Common signs include:
- Oil leaking onto the engine block
- Burning oil smell
- Oil pooling around spark plugs
- Engine misfires
- Low oil levels without visible drips
Even small leaks should not be ignored, as oil can damage ignition components and rubber hoses.
Simi CDJR technicians routinely identify valve cover gasket leaks during routine inspections.
