I have a 2003 Ford Powerstroke diesel and it stop on me while driving down highway. I had towed home and had a ford technician to come by to diagnose my issue. He ran several pressurized and computer type test. He found that the oil pump was bad. I had the icp, ipr, oil pump, and oil cooler replacedon it. I also did the egr delete. Well it started right up with no issues but after running it for about 15 to 20 minutes I noticed the coolant reservoir was dark. I opened the reservoir cap and there was oil in the reservoir very dark oil. It seems to be coming from the coolant hose from the intake. What’s causing this it has brand new cooler and it never showed this before the pump going out and no start. Oh yeah it’s a ford excursion. I’ve drained the coolant and refilled but still oil appearing I’m guessing while it’s cranking it starts slowly appearing.

This is a tell-tale sign of there being a leak in the oil cooler. Either one of the seals was installed incorrectly or there was a leak in the tubes right from the factory. If it is brand new and a Ford part, I'd suspect a pinched o-ring, so hopefully a simple R&R of the seals will fix it. If you used a Dorman, I would just toss it and get a Ford part. Oh....and make sure you get the seals/o-rings from Ford....like actually buy em from a dealer to be certain. LOTS of fakes out there and you will get leaks.

I’m sorry it’s the 6.0 and it’s never had coolant issues. It’s had a coolant filter system on it for about 4 years now. I recently replaced oil pump and while having the intake off I thought it would be a good time to delete it. Soon after the install I cranked it and it fired up within seconds, but I was checking for leaks and noticed that the coolant was dark. I checked the coolant and noticed oil. I #### the truck down soon as I noticed. Truck wasn’t running very long and I drained the degas bottle and cleaned it. Oil still appeared within seconds of being cranked. Never had overheating issues nor does it has oil on dipstick or white smoke. Seems to run normal other than the oil in coolant.
