04 6.0 HELP Diagnostics

[Landonschert]

Ok i have a 04 6.0 with 106.000 miles, no pipe, maybe a programer. and towed a fairly large boat 25-30ft.

Well i got it and it was over heating and the coolant was low, i checked the ex. pipe and coolant was present so EGR cooler was pulled to discover sure enough BUSTED, BUT i pulled the oil housing and Mixed in the oil was coolant.. also oil was in the Y pipes in to the turbo, so blown head gasket, or leaking oil cooler or cracked head???
