After installing a new upper hose on my 49 Champion, I started her up to check for water leaks. No problem there, but I noticed tiny bubbles leaking out of #1 cylinder where a little leaked coolant had gathered in the plug depression. I replaced the plug with a new one with no change. I also noticed a tiny nick on the edge of the spark plug hole. I checked the other plugs by putting a few drops of water in the plug despression, and #4 is doing the same thing. Is there any way to stop this with some kind of Loctite (for example) product? I first thought of plumbers tape but figured that would not stand the heat.
The engine was rebuilt last year, runs great. Has anyone had this specific problem? Thanks guys for your help.
