The fella that put the blame on Virginia's motor locking up, at a slow manifold gasket leak I'd say nailed it. I haven't pulled the pan yet but no cylinder scoring. But the valve covers and filler tube are coated in some nasty red scale kinda goop. I've scrubbed the insides with a wire brush and gas, scotch brite and super cleaner till my arms are tired. This stuff couldn't have been good for the bearings. I'm calling clean enough. I was going to leave them black, but with the orange block and heads I had to paint them. Drying after the last bath. Ready for paint soon.
