Troubleshooting & FAQ
How do I know if my lower gaskets are failing?
Common symptoms include water in the engine oil (milky appearance), oil in the coolant, visible external fluid leaks from the engine seams, or persistent engine overheating.
Is this kit compatible with all 8.2L engines?
This kit is specifically designed for the OMC 8.2L 502 King Cobra model manufactured between 1992 and 1993. Always confirm your engine's OEM part number requirement is 17140 before ordering.
Do I need to use sealant with these gaskets?
Always consult your engine’s official service manual. While many modern gaskets are designed to be installed dry, some applications may require a specific type of sealant on certain areas for a perfect seal.
What is the recommended replacement interval?
Engine gaskets do not have a fixed service interval. They are typically replaced during an engine rebuild, when a leak is diagnosed, or as a part of preventative maintenance on older engines.
