I recently rebuilt the engine in my 52 cub. It runs great but has ongoing issues with the head gasket. I had the block tended to at a machine shop here in NH and it was inspected, rebored, etc. and given a clean bill of health. I finished the rebuild, got her running and antifreeze came out around the head gasket on the manifold side first time I started it. I retorqued the head bolts as recommended but still leaked. I watched a utube video suggested using copper coat. I got new gaskets and gave it a try. Same thing but not as bad. I ordered a new head. Put this on with new gaskets and does not leak on the outside of the head but seems to be leaking on the inside. This a guess by the fact that there are bubbles in the radiator antifreeze and abnormal amount of white smoke or steam coming out the exhaust. Anybody else run into this problem or have any suggestions? Thanks!
