Good point, makes cleaning out rust/gunk behind cyl #4 even more important. But in this particular posters case he says he has a recored radiator and rebuilt engine - i would hope whoever rebuilt the engine dunked and cleaned inside the waterjacket.

This is where one of those thermal cameras would be great to use to detect hot spots in both block and radiator.
