Troubleshooting & FAQ
How do I know if this gasket will fit my engine?
This gasket is compatible with Volvo Penta 2003T, D2-55, and MD22 series engines. Please cross-reference your engine model and original part number with the information in the compatibility tables. Always verify by comparing the product images to your old part.
What are the signs of a failing exhaust gasket?
Common signs include a ticking or puffing noise from the engine bay that changes with engine RPM, visible soot or black streaks around the exhaust connection, and the smell of exhaust fumes in the engine compartment or cabin. Reduced engine performance can also be a symptom.
