6.9 diesel cooling problems

I have a 84 F250 4X4 with 6.9 and its driving me crasy. The problew is I can't keep coolant in the radiator, have replaced the pump, cap, themosat and housing, all the hoses and had the radiator check out. The problem is the coolant goes into the overflow tank but does not come back, the coolant level in the radiator rises when you give it throtlle and then slowly goes down, the upper radiator hose increases pressure to where you can't even squeeze it. Please ant help or thought with this problem would be greatly appreciated.


Thanks
Luke
