Troubleshooting & FAQ
How do I know if my cylinder head cover gasket is failing?
Common signs include visible oil leaks around the head cover, a smell of burning oil as it drips onto hot engine parts, or a dirty, oily engine top covered in grime.
Is any sealant required with this gasket?
This gasket is typically designed for a dry installation. However, always consult your engine's service manual, as a small amount of RTV sealant may be recommended at specific points, like corners or joints between engine components.
What happens if I overtighten the head cover bolts?
Overtightening can crush, split, or deform the gasket, leading to immediate leaks and seal failure. Always use a torque wrench and follow the OEM-specified torque values and tightening sequence.
Can I reuse my old cylinder head cover gasket?
No. Cylinder head cover gaskets are single-use components designed to compress and create a seal. Reusing an old, compressed gasket will almost certainly result in leaks.
