Engine is now receiving a long overdue rebuild as the cause of the oil in the water could not be found. Head gasket looked okay, head pressure tested okay, Oil cooler pressure tested okay. Not much remains except the block.

You can pressure test the elements in the oil cooler and it still put oil in the coolant around its outsides. Just a thought.

Some trucks have a tranny heat exchanger that uses the coolant system, and they can go bad too.

Hopefully you did not take it to a stealershit or some other complete moron of a shop to have it half-arssed re-built. That is all most of them do any more.
