Installation Notes

  1. Ensure the engine is completely cool and the battery is disconnected before starting.
  2. Carefully remove the old, failed gasket. Clean any remaining gasket material or carbon deposits from both mating surfaces.
  3. Verify that the surfaces are clean, dry, and smooth to ensure a perfect seal.
  4. Position the new gasket, making sure it aligns with all bolt holes.
  5. Reassemble the components and tighten all fasteners in the sequence and to the torque values specified in your engine's service manual.

Troubleshooting & FAQ

What are the signs of a failing exhaust gasket?

Common symptoms include a ticking or puffing sound from the engine bay that may change with engine RPM, decreased engine performance or fuel efficiency, and visible black soot or exhaust residue around the manifold connection.

Do I need to use sealant with this gasket?

This gasket is designed to be installed dry. The use of sealant is generally not required or recommended, as it can interfere with proper sealing. Always refer to your service manual for model-specific instructions.

Can this gasket be reused?

No. This is a single-use, crush-style gasket. It should be replaced any time the exhaust manifold or connected components are removed to ensure a reliable, leak-free seal.

Is this a genuine Volvo Penta part?

This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials and manufactured in an ISO 9001 certified facility, with batch inspections for quality and consistency.

How fast do you ship?

We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free, and expedited options may be available at checkout depending on your location.
