I checked everything you guys said to look at. The head nuts all had 2 to 3 threads to go before they would bottom out not counting the washer thickness. I have the heater bypassed and the radiator has a new core that,s been leak tested to 10 PSI. Filled the radiator back to 1 inch below the cap seal with water and got all the air out. Then drove the car for 1.5 hours checking for leaks and saw none also pulled the dipstick several times saw no sign of water on it and not really foaming . The breather had a little blowby and not much from the crankcase tube. The oil pressure stayed at 38 to 40 PSI at 55 to 60 MPH that leads me to believe it,s not being diluted by water. Retorqued the cylinder head hot and had no movement on any nuts "this was the fourth time I have retorqued it hot"

I let the car set overnight and checked the water level the next morning in the radiator it was down a 1/2 inch. Then put the front tires up on blocks so the oil would drain to the rear of the oil pan. When I cracked the drain plug saw no water come out then let the oil set overnight. The next morning when I slowly poured the oil into a clean drain pan saw some water in the bottom not much. Not sure where to go from here.
