How do I remove goop from oil cooler failure

[sweetdeeillusion]

Ok. I am a Detroit/ Cummins and Cat certified tech and have had more head and head gasket failures than care to remember in 30 years. But my 05 F350 6.0 lost its oil cooler 650miles from home. Ok no big deal, replace the cooler flush the system and your done. Er no! Houston we have a problem, my oil and the Ford Gold coolant have combined to make goop. Small parts are not a problem. Degreaser, some Dawn and hot pressure washer sort it. But not so the motor or radiators. Ideas as to what chemical mix will remove the goop.

I am one step away from removing the motor and stripping it.

By the way I had a ISB4e oil cooler fail two weeks ago, same failure as my 6.0 but no truma of goop. No Ford coolant!

Truck has 111k miles on it. Till warranty ran out serviced by suppying dealer from new. Ford not interested. Suprise!
