Installation Notes

  1. Disconnect the negative battery terminal for safety.
  2. Drain the engine oil completely into a suitable container.
  3. Carefully locate and remove the oil pump assembly, noting the position of all fasteners.
  4. Remove the old gasket. Thoroughly clean both the engine block and oil pump mating surfaces, ensuring they are free of old gasket material, oil, and debris.
  5. Position the new gasket correctly on the engine block or pump.
  6. Reinstall the oil pump assembly. Tighten the mounting bolts in a crisscross pattern to the manufacturer's specified torque values to ensure an even seal.
  7. Refill the engine with the correct type and amount of new engine oil.
  8. Reconnect the battery, start the engine, and carefully inspect the oil pump area for any signs of leaks.

Troubleshooting & FAQ

How do I know if my oil pump gasket is failing?

Common signs of a failed oil pump gasket include visible oil leaks around the oil pump housing, a low oil pressure warning light on your dash, or unusually high engine operating temperatures.

Can I reuse my old gasket?

No. Gaskets are designed for a single use. They compress and deform to create a seal, and once removed, they will not provide a reliable seal again. Always use a new gasket when the oil pump is removed or replaced.

Does this gasket require any sealant?

Typically, composite gaskets like this are installed dry. Applying sealants can sometimes interfere with proper sealing. However, always consult your engine’s official service manual for model-specific instructions.

How critical is the bolt torque during installation?

Extremely critical. Uneven or incorrect torque can damage the gasket, cause leaks, or warp the pump housing. Always use a torque wrench and follow the sequence and specifications in your service manual.

Is this gasket compatible with models other than those listed?

We can only guarantee fitment for the Parsun models explicitly listed. For other brands like Mercruiser and Tohatsu, compatibility relies on matching the part number. Do not use it if your model and part number are not listed.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
