Oil in antifreeze issue

I am out of ideas now. I have a 1987 944 Turbo and have a issue with water and oil mixing. When I fist noticed it I figured the oil cooler was leaking so I replaced the gaskets, drove the car 50 miles and still the same issue but getting worse. I pulled the oil cooler again hoping I screwed up replacing the gaskets. New set of gaskets and still same issue.
I have the car partially pulled apart hoping to find a easy fix. I put a coolant pressure tester on the system and cannot get it to even hold a pound, it pushes the pressure straight into the oil system. I have the oil filter off and as soon as I apply pressure to the cooling system it pushes air/oil out of the center of the oil filter adapter. I took the oil cap off and cannot hear air bleeding into the crank case. I bypassed the turbo cooling lines also hoping it was a bad turbo, but still no luck. Where else do I look?
Has a new head gasket 3000 miles ago and other than the leak it runs perfect. Is there some other seal in the engine that can cause this? I cannot even run the car now because it will pump all the engine oil into the antifreeze in about a minute. Any help would be awesome.
I just want it fixed so I can sell it.

Did you pay close attention to the O-rings on the short aluminum pipe between the oil thermostat housing and the block? See the article linked below for details. Is car bone stock or is modified and, if modified, any chance the new head gasket blew quickly for the same reasons the first one went bad?

Other possibility -- however rare and unlikely -- is a cracked block, head, etc.
