Dt466 1990 oil in water

Please help ive spent 1000s of dollars on this engine my mechanic has just replaced a few gaskets on front of motor which involved taking head off . All gaskets replaced . Drove for a week now oil is coming out of overhead water tank. Took oil cooler off and pressure tested it and it was perfect. Where else can oil get into water if oil cooler is fine and they only recently changed the head gasket.

There are a couple of places on the head gasket. The cylinder sleeves can leak at the bottom seal as well.
Oil coolers an pas a cold pressure test yet fail when hot.
It sounds like something went wrong with the head replacement, perhaps they cut the gasket placing the head?
