shoot the oil pan after a had run, should be about 150 or higher. pressure test the engine with the intake manifold on it, listen in the valve cover or see if the oil level is getting higher. It really sounds like condensation, that motor needs to run hotter than its indicating. I used to work on some high perf motors that the oil ran too cool when they wern't run hard(especially jet boats), and they would allways have condensation in the oil. We tore one motor all teh way down looking for a problem before we figuerd out what was happening. Ended up only needing to build a dog house for the engine(it sat out in the open), it trapped enough heat for the engine to stop condensating and allowed teh hot oil to steam the moisture out. I would make sure the thermostat is installed correctly, that engine should hit the prescibed temp, or at least close to it. Sounds like it is bypassing too much water. What year model and type cooling set up does it have? Center rise or rear hump exhaust? does it have separate hoses leading to the risers? A pic of the engine and a serial number would help. 4, 6 or 8 hose thermostat housing?
