Installation Notes
- Ensure the engine is completely cool and disconnect the negative battery terminal for safety.
- Safely access the exhaust manifold. You may need to remove other components for clearance.
- Systematically unbolt and remove the old exhaust manifold from the cylinder head.
- Thoroughly clean both the cylinder head and manifold mating surfaces. Remove all traces of old gasket material, soot, and carbon deposits to ensure a perfect seal.
- Position the new gasket correctly. Do not use any sealant unless explicitly specified by the engine manufacturer for this application.
- Reinstall the exhaust manifold, hand-tightening the bolts first. Then, torque the bolts to the manufacturer's recommended specification and sequence.
- Reconnect all previously removed components and the battery terminal.
- Start the engine and carefully check for any signs of exhaust leaks around the manifold before taking the vessel out on the water.
- Important Quantity Note: Volvo Penta D6 engines require two (2) of these gaskets. D4 engines require one. Verify you have the correct quantity before starting work.
Troubleshooting & FAQ
How do I know if my exhaust manifold gasket is failing?
Common signs include a loud ticking or tapping noise from the engine bay that increases with engine RPM, visible soot or black streaks around the manifold-head connection, a noticeable decrease in engine performance or fuel efficiency, and the smell of exhaust fumes in the engine compartment.
How many gaskets do I need for my engine?
Volvo Penta D6 series engines require two (2) exhaust manifold gaskets. D4 series engines require one (1). This part is sold as a single unit, so please ensure you purchase the correct quantity for your specific engine.
Can I reuse an old exhaust manifold gasket?
No. Exhaust manifold gaskets are single-use, crush-type components designed to deform and create a seal under pressure. Once compressed and heat-cycled, they cannot be reused and will not provide a reliable seal if reinstalled.
What happens if I don't replace a leaking gasket?
A leaking exhaust manifold gasket can lead to several problems, including burnt exhaust valves, reduced engine performance, increased fuel consumption, and the release of potentially harmful exhaust fumes into the engine bay or cabin. It's a critical seal that should be replaced as soon as a leak is detected.
