[QUOTE="jp8775, post: 118912, member: 20329"] I have a 743 that has antifreeze in the oil. If I run it with out the radiator cap it seems to be ok. But if I pressurize it then there is antifreeze in the oil. When the engine is running if I have a pressure gauge on the radiator there is no pressure build up. So I assume that there is not a crack in the head but rather a head gasket issue leaking into the crankcase? Am I correct? If it was a crack in the head then cylinder pressure would leak into the radiator I assume? This is a older 743 I just purchased, seller sold it because of the antifreeze in oil issue. R&R head have it machined flat and checked for cracks? [/QUOTE]
