Installation Notes

  1. Ensure the engine is completely cool and the battery is disconnected before starting.
  2. Carefully remove the exhaust manifold, taking note of the hardware sequence.
  3. Remove the old gasket and discard it.
  4. Thoroughly clean both the cylinder head and manifold mating surfaces. Any remaining debris or old gasket material can cause leaks.
  5. Position the new gasket correctly. Do not use sealant unless specified by your engine's service manual.
  6. Reinstall the exhaust manifold and tighten the bolts/nuts in the correct sequence and to the manufacturer's recommended torque specifications.

Troubleshooting & FAQ

How do I know if this gasket will fit my engine?

This gasket fits specific Volvo Penta 30 and 40 series models. Please refer to the "Engine & Model Compatibility" table and cross-reference your engine model and production year. Verifying the OEM part number is the most reliable method.

What are the signs of a failed exhaust manifold gasket?

Common symptoms include a loud ticking or tapping sound from the engine bay that is most prominent on a cold start, visible black soot trails around the manifold, reduced engine performance, and exhaust fumes inside the boat.

How many gaskets do I need for a full replacement?

Volvo Penta 30 Series engines require four (4) of these gaskets, while 40 Series engines require six (6) for a complete service of the exhaust manifold.

Should I use sealant or adhesive when installing this gasket?

Most exhaust manifold gaskets, including this one, are designed to be installed dry. Applying sealant can cause the gasket to slip or fail prematurely. Always follow the installation guidelines in your official Volvo Penta service manual.
