I've removed my #1 #2 cyl head, 1983 Westphalia, and there are a few places where the cylinder head stud holes (right next to the combustion chamber) are eroding away and the metal (between the hole and the combustion chamber, right at the sealing surface level) is getting thin. There is one spot where a little knotch has eaten away there is a small gap (1/16th ") down from the flat sealing surface, into the wall that separates the combustion chamber and one of the stud holes. I'm not sure if the green o-ring was sealing that area, but for the past few weeks there was water getting into that cylinder (#2) and on the spark plug, so that could be the culprit. I know that many people have used JB Weld on the flat sealing surface, but I wonder if it's been used in an area like the one I'm describing. Any thoughts? John |
