Troubleshooting & FAQ

How do I know if this intake gasket fits my Volvo Penta engine?

This gasket is a direct replacement for Volvo Penta part number 840944. The most reliable method to confirm fitment is to check your engine's service manual or parts diagram for this specific part number, as detailed model compatibility lists are not available.

What are common symptoms of a failed intake gasket?

Signs of a bad intake gasket include engine overheating, coolant loss with no visible external leaks, poor engine performance or misfires (due to vacuum leaks), and contaminated engine oil that appears milky or frothy.

Should I use sealant with this gasket?

Most modern intake gaskets are designed for dry installation. However, some specific engine models may require a small amount of RTV sealant at coolant ports or corners. Always refer to your official service manual for instructions specific to your engine.

Is it necessary to replace intake manifold bolts during installation?

It is best practice to replace torque-to-yield (TTY) bolts, as they are designed for one-time use. If your engine does not use TTY bolts, you may reuse them, but ensure they are clean and in good condition. Always follow the manufacturer's torque specifications and tightening sequence.
