Hello everyone, I am reposting this from another thread, I published one in another section as well, but was pointed in this direction.
A little about the truck:
New ARP 20 mm head studs, new o.e.m. Ford Head Gaskets, EGR cooler delete, EGR valve delete, sinister coolant filter, AFE stage 2 dry intake filter, Powermax series 2 turbo, 4 inch dual exit Diamond Eye exhaust, +140 h.p. Hard tune(not in a programmer) aux external air to liquid oil cooler, o.e.m. ''Heavy duty'' Ford oil cooler, Edge cts2 insight pro (for the digital gauges). i have had the head Gaskets and stud replaced twice with-in 4-5 months, as well as the oil cooler at the same time twice, at two separate diesel shops. The heads was sent to a "machine shop, to be checked and decked or resurfaced" both times they came back saying the heads have no issues at all. The truck is still puking coolant. I have had all kinds of answers, but nothing has fixed this issue. The truck is not over heating, in fact it runs cool, today was 86 degrees, ECT=192-198 EOT=196-201 (60mph 15+minutes), not burning oil, not burning the coolant in exhaust, not mixing with oil and no oil in coolant. Passes headgaskets leak checks, but still pukes coolant. I have ordered a new degas bottle cap (was replaced at the same time as head Gaskets and ARP headstuds the first time 3-4months ago along with a new degas bottle) I am at a total loss. Please help.
Does your degas bottle have the updated level sticker? The original "low" level is now what you're supposed to use as "high". If it's overfilled, it can puke.
Were the heads crack checked? As in magnaflux?
I have seen it where some shops will give it a visual check only.
Both shops said they sent the heads out to be magnaflued?) checked and both shops said the heads had no issues. The two shops that worked on my truck are over 300 miles apart, and do not use the same machine/head shop. That means that two different mechine/head shops came to the same conclusion that the heads are not cracked or warped, and I made sure on the second go round to ask for them to check for hair line cracks. I was told they had no issues at all, This was about 2-3 weeks ago.
Hook up a pressure gauge to the degas and see what it tells you. Is your pressure driven by coolant temperature, or does it swing significantly independent of pressure?
I run my coolant level slightly below the new minimum level.
It was also puking before studs? Could it be confirmed that it had a gasket leak prior to studs?
Do you know if the machine shops pressure tested the injector sleeves or replaced? Also when resurfacing heads did anyone ck the intake man to head angles/mating surfaces?

Yes, it was puking before studs and Gaskets, yes it had a gasket leak prior to studs and Gaskets. I was at the shop when it was pulled apart. Loads of water in the cylinders, Peanut butter on dipstick. That's what prompted us to stud it. We also did the egr delete, and oil cooler change, and then the turbo (detonated) less than a mile from the shop and was replaced, the truck was tuned, intake and exhaust was added.
Then less than a month/600 miles later, still puking, we went to a new shop and new head gaskets were necessary, so new studs as well, and then two days later new oil cooler. I got the truck back yesterday, with the new oil cooler and it's still puking. The second shop ran an exhaust gas coolant test yesterday, and it passed. No color change. I do plan to hook up a pressure gauge, but can't get to it right away.

I was told by both shops the heads was pressure tested and magnafluxed, no issues found. I can not say exactly what was pressure tested because I did not ask what exactly was pressure tested. as for the intake manifold to head mating surface, I can not speak for either.
You can also pressurized the coolant system (only to 15 psig) to check to see if it holds pressure. You can use one of the vent hoses on the degas bottle to add air and to install a pressure gauge.
Make sure the cap sealing surface is smooth and is not warped and does not have gouges in it.
Put one of these in your degas line. If it gets above 15 psi, I think it still may be a head/gasket issue, or as has been said, coolant capacity with the mods may not be sufficient.
Also, I run my coolant just a little low, but watch temps like a hawk. It has been noted on the forum that putting in too much will make it puke.

I will try adding air to the system today, thanks for the advice, I would have never thought about that. I just inspected the cap, I can't see any deformation, but it rattles a good amount when shaking it, I don't remember if it did that when It was replaced. I have another on the way, it will be here on the 10-oct-2017.

I will be adding one permanent in the cab, I can't do it right now. How would I go about adding coolant capacity? It passes the exhaust/gas coolant test. With bad Gaskets, 2-3 weeks ago it failed/ the color changed. We replaced the head Gaskets and studs, then two days later the oil cooler went bad (again,3rd oil cooler in 2-3 months). Now I have had the truck back for 3 days, and is still puking. Coolant is checked daily, only filled to the min level, I had to add a gallon of coolant yesterday, i have not driven it yet today.
Update: I managed to put pressure in the system using my home compressor and turning the air pressure way down to 14 psi, at 11 psi the cap started hissing.
