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.
Wheres the oil coming from ? Could it be getting through at the water pump or timing chain area ?
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.
