Re: blown gasket

Cylinder head water jacket cover gasket. Is that the question?

Those leak all the time.

Re: blown gasket

Yeah thanks chris could this cause water to be coming out around the plug or cause it to not run right I'm going to replace it it's only 7 bucks I don't think the water is coming right out the plug cause it's tight to the cylinder that's pretty in possible but it's hard to see I don't see any cracks on the cylinder I'll just hope for the best

Re: blown gasket

They leak around the plug all the time. That is not the reason it doesn't run right, however. You might take a compression and spark test and post results.
