i recently overheated my 350sdl, and my 1st thought was a thermostat. when i opened the hood i noticed jelled oil oozed out of the top of the radiator seam. i looked in the coolant resevoir and there was jelled oil in there. But the oil looks fine, no coolant mixed in the oil or oilpan. So now i'm thinking headgasket. My freind pulled the head off and the head gasket looks fine. i sent the head out to be checked for warping or cracking. so far its not warped so bad, only 4-5 thousanths (not enough for a head gasket. they are checking for cracks in head tomorrow. pistons all come to top , flush. and cyl.'s are not out of round.

Has anyone else ran into this where oil is in the coolant system BUT NO coolant in the oil system?
