OK guys, my aunt finally got her M over to me and I was able to check it out a little last night after getter the Farmhand loader pulled off. She said that it keeps fowling the plugs and is hard to start and runs rough. It looks like oil is weeping out of cylinder 3 from the exhaust manifold and from the head gasket on the other side of the block. I pulled the plugs and cylinder 3 was dripping with oil...the others weren't too bad. She was told to use Autolite 388 plugs, I'm guessing that is hotter than the 386 that I'm thinking it should have? I was VERY shocked with the compression numbers of 130, 122, 140, 125. What do you guys think at this point? Initially I was thinking valves or rings but with compression numbers that high...would it maybe be valve guides instead? Either way I know I'll have to pull the head and pan to inspect and measure everything for wear. Just curious what you guys would be thinking at this point. 46 M with I believe an F4 magneto.
