sounds like you are getting a antifreeze in with the oil.

i would be checking for a blown headgasket/cracked block/ or cracked head.

if its not that i would suspect an issue with cracked intake manifold or a bad gasket on the intake manifold.

one way to see what it is if your daring, taste it. sweet its antifreeze. if it tastes like exhaust smells and gas its normal condensation.
