Oil is back in coolant. If I ever figure out where it is coming from I'll post the solution. The second job was cancelled and the truck went to auction.

Oil in Rad
Tom sorry to hear about your oil problem i see it's been awhile since your last post. Not sure if you got it figured out yet or not. If it takes a while for the oil to show up in your Rad it probably your injector cups. What happens is oil sit on top of the head around the cup and as the coolant system cools it make a vacuum pulling oil into the coolant. Isuzu had a problem with that era engine because they only had one O ring on the cup. They updated the heads and cups i believe in 2006. I hope this helps. Not a a real big job to do if you have the tools

Well, I had a long conversation with the GMC dealer and they claim they called tech support. They recomended replacing the engine oil cooler. I sent the truck to them and they replaced the oil cooler and flushed the cooling system and replaced all the hoses because of swelling. 2 months later and the oil is back. I appreciate the feed back about the injector cups. When the hoses swell up and start leaking again, I'll get the cups replaced.

Thanks to DieselTech04401. The injector tubes fixed the oil in coolant problem.

A little simple Green in the cooling system is a great way to clean that part of this up. Seen the CAT mechanics do this quite a few times.
