I would think that if you still have "Milk Shake Like Oil", take note of water level in radiator AND oil level on dip-stick. Let the car sit for a few days....then check the water level in the radiator AND check the oil level on the dip-stick.

If the water level has dropped AND the oil level has increased; it would mean you still have a leak some where. (Either a gasket problem, a head/block surface problem or the head is not torqued down)

If the water level AND oil level haven't changed then there is residual water in the oil passages some where.

I just recently went through this "Milk Shake Thing" and pulled the oil pan to get things cleaned up after replacing a leaky head gasket.
