Nope. Milky oil-oily coolant=basically the same thing-Oil and coolant mixing. In my experience, there's only 4 ways that happens:
1: Blown head gasket.
2: Cracked head.
3: Cracked block.
4: Purposeful sabotage=someone pouring water into your crankcase or oil into your radiator.
Use a cooling system pressure tester on a warm engine. Pressurize the system to about 13-15 PSI. Listen for any hissing or bubbling sounds coming from the block. Use a piece of hose or a long piece of metal to help pinpoint the source of the bubbling.
