Tired and frustrated with the glycol in oil leak..

I think its a head gasket. Running your oil at the temps your running at is burning the water out of the oil in the pan and the motor. The valve covers run quite a bit cooler and cool faster when you shut the motor down..hence the milk shake but not the creamy oil.

Are you loosing water? Something you might try if you have it back together and didnt fix the leak. Put a radiator pressure tester on the radiator. Pump it up to about 15 psi...fire it up and let it run for just a few minutes. Then check your oil and see if you have any coolant present. Need to check it before it has a chance to get hot enough to burn it off.

Just a thought.

I hope it isn't a head gasket but it's looking more and more that it may be. I'm probably going to pressure test the entire engine next as soon as I can fabricate some more blank flanges for the other head and water pump block inlets. At least that will tell me if I'm headed for a further tear down.

I'm losing hardly any water, just enough that would be accounted for with the minor coolant leak into the oil.
