[Fot] Ever seen this one???

Oil in the radiator WITHOUT oil in the water? Figuring head gasket but 
seems strange... I know I have a head bolt issue. New block had a repair 
- machinist said it looked good but it topped out at 90 ft lbs.

Had interesting overheating issue - runs fine 180-190 but when I turn it 
off, the water boils in the motor/radiator. 50:50 prestone... 4 lb cap. 
Water goes into overflow bottle but does not appear to be pulled back 
into the radiator when the engine cools. This was before the oil / 
radiator issue.
