I have a 97 ford F350 power stroke I am getting oil in my coolant. I put new O rings and gaskets on the oil cooler and still getting oil in. Although I did not inspect the cooler itself for any defects. does anyone have a suggestion If there are other things I should be looking at. head gasket? Inspect the cooler better and if so what should I be looking for? The truck runs fine but if I hook my dump trailer on it, it over heats

 

Hey Mike Rose, I think you Need to be in 7.3 section buddy, this is 6.0 forum. I would be checking head gaskets . .

 

I don't want "opinions, I want experience and what has worked for you ?
Opinions is what we all sit on !
