Troubleshooting & FAQ
How do I know if this gasket fits my specific engine model?
This gasket is designed for Volvo Penta 30 and 40 series diesel engines. Please verify your exact model against the compatibility list provided above. Cross-referencing the OEM part number (1542123 or 1542177) is the most reliable way to ensure a correct fit.
How many gaskets do I need to purchase?
Volvo Penta 30 Series engines require four (4) gaskets for a complete replacement. Volvo Penta 40 Series engines require six (6) gaskets. This listing is for a single gasket, so please adjust your order quantity accordingly.
What are the signs of a failed exhaust manifold gasket?
Common symptoms include a loud ticking or hissing noise from the engine bay (especially when cold), a noticeable decrease in engine performance and fuel efficiency, visible soot or black streaks around the manifold-head connection, and the smell of exhaust fumes in the engine compartment.
What is the difference between part numbers 1542123 and 1542177?
