Oil Cooler Problem

[dougconner]

I have an 02 F350 7.3. I had the oil cooler rebuilt by a local shop, but was still getting lots of oil in coolant after being flushed several times. I had oil cooler replaced by a Ford dealer in Wisconsin. I drove approx 600 miles and lost almost a gallon of oil into the coolant. I took it to another Ford dealer in
Indiana. They installed another new oil cooler. I then headed back to Texas. I went through 2 gallons of oil and several stops to add oil and siphon oil out of coolant. The engine has new head gaskets injector O rings and cups. Does any body have any ideas as to what is going on? It is at a local Ford dealer now. Any help would be greatly appreciated.

hope that was under warrenty since the dealer must have messed up something.

It is under warranty, but 2 have been replaced by Ford dealers

at least it not outta pocket. Make sure they flush out both..

[dougconner]

I was hoping for a little more input other than I hope it's under warranty, and make sure they flush out the system. I'm sure I'm not the only one out there that has had this situation. I don't trust the dealership to get it fixed. I've been told by 2 other dealerships that it was fixed and it wasn't.

Why were the head gaskets replaced, was the truck overheated or just to pull the heads to replace the cups?

My 97 had a crack on the inside of the end caps it was mixing the oil an water

[dougconner]

The heads were pulled and magnafluxed to check for cracks. The truck had over heated 3 or 4 times because of stuck thermostat, which was caused by all of the oil in coolant. The heads checked ok, no cracks. They couldn't go back togather without replacing O rings and cups.

Weak... That would point me to a cracked block if you know the heads were properly pressure tested between the HPO feed and the coolant jackets. I would think that is a pretty tricky area to pressure test, and how I have seen pressure tests commonly done they usually pressurize the coolant jackets looking for leaks in the combustion area/intake/exhaust ports. You may want to have them look at the heads again checking for leaks in the HPO feed area when the coolant area is pressurized before you have the block pulled. Good luck, I would be pretty pissy by now LOL.
