oil in radiator dilema
I have a 89 Mustang, 5.0 bored out to a 306. GT 40 heads and intake with a Paxton Supercharger. I'm running 10w 30 Mobil 1 oil. Last month it needed a quart of oil which isn't the norn.
Now I have engine oil in my radiator. Not the creamy coffee with cream looking stuff, straight brownish black engine oil floating on top of the anti freeze. Yet, theres no anti freeze in the oil in the engine ?
Car runs great with no issues, the plugs are a nice light tan colored and it doesn't smoke or leak.
The symptons aren't really right for a blown head gasket. Was going to pressurize each cylinder with air and see if I get any bubbles in the radiator. It's just strange that I'm not loosing any anti freeze. If oil is getting into the cooling system when it's running, anti freeze should be getting into the oil when you shut it off.

why don't you think its a head gasket? because that it is what I'm thinking it is for sure.I have seen them blow between an oil passage and the water jacket. if you blow it on the pressure side of the oil passages you will get oil into the radiator due to the pressure difference. and if you blow it on the return (low pressure side) then you will get coolant into the oil pan. there are a lot of different ways you can blow a head gasket. majority of the time oil in the radiator is a head gasket, slimmer would be timing cover/intake ( higher chance it would be in the pan).

yea sounds like a head gasket to me as well. I recently changed the head gasket on my acura integra (different motor but same concept) cause the coolant was disappearing. I would let the car sit for a while then get in it and start it up. the car would sputter for a few seconds til the coolant got out of the cylinders. No oil got mixed up with the coolant so as Skunk stated you can def have a blown head gasket and not mix the fluids together
