Can any one help me with rebuilding the engine oil cooler on a 1992 F350 7.3 diesel. I'am getting engine oil in the coolant. Already done head gaskets .

I have a 93 ford 7.3 idi turbo diesel with the same problem and have the engine tore down to the crank. The other option other than the head gaskets (which would cause coolant on the heads themselves) would be a leaking oil cooler. Im going to tear into mine today and see if it's the tube between the mounts that's sprung a leak. The only other thing I can think of it being is cativation in the cylinder walls (electrolysis?) Good luck.
