Troubleshooting & FAQ

How do I know if my cylinder head gasket is failing?

Common signs of a blown head gasket include engine overheating, white smoke from the exhaust (burning coolant), milky or foamy engine oil, loss of engine compression, and visible coolant or oil leaks from the engine block/head seam.

Will this gasket fit models older or newer than 1993–1999?

While this gasket is verified for the 1993–1999 model years, it is highly likely to fit earlier 9.9 and 15 HP crossflow models. The best way to ensure compatibility is to match your original part number to the ones listed in our Part Number Matrix.

Is any sealant required during installation?

Generally, modern head gaskets like this one are designed to be installed dry without any additional sealant. Using sealant can interfere with the gasket's ability to seal properly. Always follow the specific instructions in your engine's service manual.
