Wow... we got nearly the same result. The plan; drill a hole in the old cap so it would relieve pressure and prevent the
overflow. Except that when the truck started, it immediately began whistling... through the hole. Never even moved it, after explaining why numerous times, the concept goes unrealized. He understands the blown EGR cooler but not the coolant in the tailpipe or blown head gasket. It has to be something else causing the issue of over heating. Of the two smaller lines feeding the degas, the one from the passenger side has a large bolt stuck in it, it could be that line causing the issue.
It's being towed to a commercial diesel shop for evaluation and hoping that the repairs will be around $500.
Plugging the EGR cooler vent line to the degas can definitely cause overheating and even EGR cooler failure, but in his case it sounds like plugging that line might have been a reaction to the overheating, not necessarily the cause.

At least it was a bolt and not duct tape... some people have unique thought processes
For those of you looking at this thread and are either looking to buy, have just bought and/or having issues....
A short drive and a device capable of reading live data is MANDITORY to determine engine health. I'm not a 6.0 guru by any means, this vehicle was a total disaster for a buyer that doesn't know what to look for. The seller KNEW it had issues that were not disclosed at time of sale, they even touted a passing State inspection, clean exterior/interior, newer tires and the word of no known issues to date.
At minimum, a gauge of sorts ($150 or less) a few hours of research and/or a friend/member from here would have saved him $4300, tax, title and tags, insurance cost and now towing. It's over heated 6 times I'm being told. 2 times on the way home from school, 19 miles away and 4 times within 4 miles of the house.
A simple drive on the highway would have found a good portion of these issues... He didn't even drive it on the highway!
Drive it hard, get a gauge, get educated, and if you dont do any of these... bring someone who knows!
I've been looking to buy a 6.0 for over a year now. I think I'm close to test driving 12 different trucks. I always take by Bluetooth ODB reader and Torque Pro app.
Half the trucks I tested had plugged oil coolers. Of those half also had a bad FICM.
The other good oil cooler and good FICM half one had a confirmed bad head gaskets. It was tuned with stock TTY bolts. I can't say the others didn't have head gaskets issues but I didn't have any good reason to suspect they did.
It pays to take one for a test drive with proper monitoring. It will at the very least let you know what you are getting into if you decided to buy.
The thing about it Randy, is that you know you could have helped them avoid this, but they wouldn't have listened in the first place!
We probably all have family or friends that we would love for them to listen to our advice -- I wouldn't dream of going there on something like our 6.0s; but have tried to help in areas I do know a tad or two on other subjects: would they take a bit of time to do some financial planning?! NO! Just bitch when the future doesn't "fall" their way...
Any consolation, he did say that I was correct. The new plan; part the bus out since it's a loss. Pick & Pull said they will not pick it up. I offered $200 reluctantly and then told him to pull the plates, cancel insurance and push it onto the road. Call a tow truck and claim it abandoned. Tow company tows it and scrapes the thing... Or spend the next year parting it out while sitting in your yard!
The neighbors will go nuts as it's a very upscale neighborhood.
I told him that since it got so hot, anything from the motor is questionable and at minimum needs inspected, meaning a full teardown. I offered to take the injectors @ $200 for cores.
Funny part, the commercial diesel shop won't work on it and asked it be removed ASAP. He asked "how come". Same reason they never did a single test during diagnosis, they don't know how or want to learn and they gave the standard response for 6.0L
diesel.
Jack, your correct. He did mention they never even said anything about the other stuff like the injection module. I asked what about the cause, they never found that either, if you don't fix that, it will do it again.
Either not a very good diesel shop or since they were not related to it could shed the attitude or problem ASAP.
Maybe. There is a guy here who is an ambulance hunter, maybe he wants to upgrade the carrying capacity. It's about the state of operation he acquires and asks help for .......
Just like a former BIL. He had an oil filter for a ford with 3/4 threads and just to save a couple of bucks he ran a 13/16 tap into it so he could use it on his chevy, didn't matter that all the shavings went down the center, ie outlet side of the filter and the gaskets where a different size he was sure the filter would catch them and if he tightened it enough it wouldn't leak. I had to put an engine in it 2 weeks later, of course I had to provide free labor and the junk yard engine he bought had well over 150K on it.
