Seems lots of folks are having water in oil issues.
Two questions if anyone can help...
Anyone use a cylinder hone to clean the surfaces where the O-rings sit? Not to remove material, just clean the roughness off(400 grit). These aren't pretty, but the O-rings looked OK. Plan is to clean up, and smooth with epoxy(unless there is something better).
Second, found a big casting flaw in the tunnel that feeds water back the side of the engine. Anybody know how thick the iron is there? It is deeper than the picture suggests, maybe 3/16" or a little better. Thought I would clean it up and epoxy it.
We pulled the pan and pressurized it, no coolant on the cardboard under it after 2 days.
Ran it with manifolds removed, no bubbles in the coolant right up to boiling. Head gaskets looked good, though the rear one didn't seem as tight as the front 2.
An acre of plowing would put over a quart or coolant in the pan.
I have another block but don't want to change it unless I have to(it might not be any better.
