Installation Notes

  1. Disconnect the battery before beginning work.
  2. Remove any components obstructing access to the valve covers, such as brackets, hoses, or wiring.
  3. Unscrew the center bolts holding the valve cover in place. Note their positions if they are different lengths.
  4. Gently tap the valve cover with a rubber mallet to break the seal, then lift it off. Avoid prying, which can damage the surfaces.
  5. Remove the old gasket and any old sealant or residue from both the cylinder head and the valve cover. A plastic scraper and degreaser are recommended.
  6. Ensure the mating surfaces are completely clean, dry, and free of oil before proceeding.
  7. Press the new gasket firmly into the channel on the valve cover. Ensure it is seated evenly all the way around.
  8. Carefully place the valve cover back onto the cylinder head, aligning the bolt holes.
  9. Hand-tighten the bolts first, then torque them to the manufacturer's specification in a crisscross pattern to ensure even pressure. Do not overtighten.
  10. Reconnect any components that were removed and start the engine to check for leaks.

Troubleshooting & FAQ

How do I know if my engine uses center bolt valve covers?

Center bolt valve covers, common on 1987 and newer GM V8 engines, have four bolts located in the center of the cover. Older engines typically have perimeter bolts along the outer edge. Visually inspect your current valve covers to confirm the bolt pattern before ordering.

What are the common signs of a failing valve cover gasket?

Symptoms include visible oil leaks around the valve cover, a burning oil smell from drips onto hot engine parts, low engine oil levels, and a dirty or oil-soaked valve cover area. If you notice any of these, it's time to inspect the gasket.

Can these gaskets be reused?

No. These are single-use gaskets. Reusing a valve cover gasket, especially a molded rubber one, will almost certainly result in leaks as it has already been compressed and heat-cycled.

Is sealant required for installation?

Generally, these PermaDry molded rubber gaskets are designed to be installed dry without any additional sealant. However, it is best practice to apply a small dab of RTV sealant at any sharp corners or joints, such as where the intake manifold meets the cylinder head.
