Welcome to the forum.

Is there any erratic running to indicate a cylinder dropping out? I just posted some pics of the test jig I am making for oil coolers.

I would definitely start simple with the oil cooler. Maybe a sompression test to help steer you away from the head gaskets. Good luck

Oil in water is usually the oil cooler.There is much more pressure in the oil then the radiator,so the oil travels from the cooler to the cooling system. You wouldn't be likley to get oil in the cookant from a head gasket as all there is for oil flow through the head gasket is oil drains , which are not pressurezed.

Of course Murphy has made many exceptions to the rules.

Welcome to the OB Brotherhood!

My vote is for the oil cooler, it is the most common cause for this problem and a realitively easy fix

It's a 6.9 where is the oil cooler, 750 dollar farm truck would it hurt to drive it?

If they are in the same place as the 7.3L then they are up by the radiator.

Actually it's under the drivers side exhaust manifold, thAT BIG long tube that ends in the oil filter mount on the back end.
Another possible place to get oil mixed in is the valley pan gasket, or the water pump gasket, but these are rare occourances.

Thanks for the help, Had one on an old block I have, got new o rings from Ford. Learned how to rebuild it from a thread I found on here, worked just like it said it would. Will put it on in AM Will Let you know how it comes out. Thanks again.

So what is the small radiator looking thing that i described? is that part of the tranny cooler?

Yes.

 

['94IDITurbo7.3]

Yes.

so we have the standard cooler inside the radiator and then another external mini rad for more tranny cooling?

My truck doesnt have any type of external cooler aside from the a/c. I do believe there is an additional system run through the radiater though. I really havent looked that close at mine yet though, could very well be the trans though...
