Just took another 8N on trade. This one seems to have black oil in the crankcase (not milky) and black oil in the radiator. I'm having a hard time guessing the cause since this is flathead and there would be little reason to have oil in the head, which rules out head gasket. Seems most problems would allow water into the oil easier than oil into the water?
Anyone have an idea?
