I had a timing belt 3.0 engine that went bad it got hot only a little, while i was in the front i sleeved the crank seal and replaced the water pump, after start up ,miles 400 or so milky antifreeze or oil in the water ,no heating problem no water in the oil , is it possible that the new water pump is letting engine oil in the system without putting anything into the oil ?
or do I have a head gasket or crack happening? I flushed the system but that oil milk is bad stuff to completly get out to put in bars leak best engine stop leak to no avaiil possiblly since it was still residue stuck with the oil antifreeze goop . ideas?

Check tranny fluid
you may be mixing tranny fluid with the coolant due to a cooler failure inside the radiator

I have never seen water pump allowing oil into the coolant system it just no way
no common jets or way for it to do that
look for something else
are you sure its engine oil ???

FOUND IT, HEAD GASKET CORNER OIL FEED ,SEEMS SINCE OIL PRESSURE IS STRONGER THEN 16 LBS, OIL GOES TO WATER, NOT IN COMPRESSION SIDE.
