Engine oil that has the appearance of "Chocolate milk" is usually the result of water
in the oil.
Some possible causes are:
Intake manifold gasket installed incorrectly.
Blown head gasket.
If the modulator valve was broken internally and allowing trans fluid to be sucked back to the intake manifold at the vacuum connection, this oil would go out the exhaust and would /should cause excessive exhaust smoke. It would not enter the engine oil to mix with it.
