Installation Notes

  1. Disconnect the vehicle's battery as a safety precaution.
  2. Thoroughly clean the area around the valve cover to prevent debris from entering the engine.
  3. Remove any components obstructing access to the valve cover (e.g., wiring, hoses, brackets).
  4. Carefully unbolt and remove the engine valve cover.
  5. Remove the old gasket. Meticulously clean the gasket channel on the cover and the mating surface on the cylinder head. Ensure both surfaces are completely clean, dry, and free of old gasket material or sealant.
  6. Press the new gasket firmly and evenly into the groove on the valve cover.
  7. Reinstall the valve cover. Hand-tighten the bolts, then torque them to the manufacturer's specified sequence and value to ensure even pressure. Do not overtighten.
  8. Reconnect all previously removed components and the battery terminal.
  9. Start the engine and carefully inspect for any signs of oil leakage around the valve cover.

Troubleshooting & FAQ

How do I confirm this gasket fits my specific engine model?

This gasket is designed exclusively for the Volvo Penta D3 Series engines (110 to 220 HP) made from 2003 to 2022. Please verify your engine model against the "Engine & Model Compatibility" table before ordering.

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

Symptoms include visible oil leaking or seeping from the top of the engine, a burning oil smell as oil drips onto hot exhaust components, and an unexplained drop in engine oil levels.

Do I need to use RTV sealant with this gasket?

This gasket is typically designed for a dry installation. However, always consult your engine’s official service manual, as some applications require a small amount of sealant at specific points, such as where engine timing covers meet the cylinder head.

Yes. Part number 31430317 is the current part that supersedes the older number 30777600. It is the correct replacement for both.
