After installing a "new to me" cylinder head on my 1951 235, it is weeping antifreeze from between the head and the block on the right side, most noticeably directly under the #1 spark plug. There are also some signs of leakage under #4 & #5 plugs.
It's just a tin bit, not a ton of leakage, as in running down the side of the block, but it caused concern. I had ran the engine for a total of maybe 45 minutes after the head was installed. I left the truck alone for 2 weeks while I was at college, and upon my return, there was some antifreeze seeping out. I figured since I had installed the head, ran it, and it had cooled, maybe that was normal. So, I re-torqued the head, hoping that would solve the problem. It didn't. (I have overhauled 2 1940s era tractors, and had the same issue, but re-torquing fixed them) I re-torqued it yesterday, and there was a bit of seepage there today.
I bought the bare head from Old Car Parts in Oregon, had it checked/rebuilt by a reputable cylinder head shop in Oklahoma City, and was given the go ahead by the machinist. He did check it for being level, and said it was indeed level. The head gasket I used was a Fel-Pro, and I coated both sides of it with Permatex Copper "Spray-A-Gasket", as I have done all my cylinder heads in the past.
I did reuse the old head bolts, but I'm not sure those are the problem. I also cleaned out and chased the threads in the block with a tap, so I'm sure I'm getting a correct torque reading with my click-type wrench.
The engine never blows any white smoke once it's warmed up or on start up, so I don't think it's getting into the cylinders.
Any ideas on what to do?
Thanks!
