I am almost ready for first engine start with a salvaged O-235 C2C. While doing pre-oiling the blanked vacuum pad started leaking oil. After pulling the blank I discovered a bad gasket.

So the question is:

Should I source a proper gasket?

Or is it acceptable to use high temp form a gasket instead?

I have been unable to find a definitive answer to this one.

Thanks, Matt Stecher

I’ll jump in first. Couldn’t cost much, order a new one and be done.

Your right, at the time of my original post I had not had any luck finding the part number for the gasket, but further searching turned up the parts catalog for the engine and its the #8313 that I need.

Thanks, Matt

I have torn down several engines that experienced rod bearing failures due to improper use of silicone form a gasket. Small amounts can extrude into the engine oil system and break free. They will pass through the oil suction strainer and block the oil passage in the crankshaft. Use the correct gasket and correct amount and type of gasket sealant.
