Hey all, thought I would start a new thread so everyone could read it and give their opinion. My truck is in the shop for a flute noise coming out of the degas cap. They couldn't find anything wrong with the egr cooler so they pulled heads. They also found nothing wrong with the head surfaces, block deck or head gaskets, no failures! What is going on here? They will use the heads again cause the measured up fine, how do they know they aren't cracked?

I think the main problem is that the factory head bolts stretch, which is why people replace the stock ones with studs from ARP. If there isn't a proper sealing surface from the cylinder block to the cylinder head, compression, coolant, oil, etc is going to get to places it shouldn't. In your case is sounds like it was pumping compression into the coolant jackets from an in-proper sealing surface causing it to vent through the degas cap.
They should be sending both of your heads out to a machine shop to pressure test & check the mating surface for warpage (They can check for warpage at the dealer if they own a flat edge tool).
Why can't your dealer figure this out? They should know this. To simply just slap it back together with some new gaskets would be irresponsible on the dealers part.
Get some ARP studs in that thing so you don't have to go through this again, and again....
Insist that the Heads be professionally checked at a equipped machine shop,Or replaced.A visual Inspection is just that.Just because you cannot see a problem does not mean there isnt one.The dealer is Not equipped to pressure check,Magnaflux and so on.
I 100% agree you need to have your heads checked by a machine shop! I had the exact problem Ford but mine back together twice with what seemed to be perfect heads and decks. Finally after the second time they replaced the heads and no more problems

About the only way to find out if the heads are cracked would be to magnaflux them. Few if any dealers do this.
You said they found no failures when they pulled the heads or with the EGR cooler. Presuming they are correct, my next question is, did they check the oil cooler? The TSB on puking says they are to do so. If they did not, then there is still one part of the diagnosis that has not been done.
One last question.... Did they try replacing the cap? There have been a few batchs of bad caps out there.......

Mine is in the shop as well for puking coolant. EGR cooler is fine. They are checking the heads/head gaskets this week. They are also sending them out for magnafluxing.

my truck is doing the EXACT same thing... puking out coolant our of the degas cap and making that stupid annoying fluting sound coming out of the degas cap. its an 05 with 80500 miles. My fathers 6.0 also does the same thing just not as much.
OK I'm not to ashamed to ask. What is a degas cap, and where is it located? My 6.0 is losing anti-freeze too. Are there any good diesel shops in NW Ohio? And if I need head studs how much money should I plan on spending?
mine was loosing coolant, pressure in the degas bottle. They did egr cooler and headgaskets. AFTER 2 more Egr coolers, they changed the oil cooler. No more problems. Have the oil cooler changed. They said they are clogging up on the coolant side, restricting flow. The oil temp boils the coolant, creating steam and the steam then melts the solder in the egr cooler, wiping that out. 6 trips to dealer to figure it out.

Thanks for the info. I am monitoring it almost everyday and will look for a reputable shop in NW Ohio. If I didnt have so much in my truck I'd trade for a Duramax and an Allison.... Thanks again!
Well - has anybody had a resolution to the coolant problems? I ask because, sadly, mine is doing the same thing now that I'm 60 days out of the 5 year warranty (about 86,000 miles)!
Coming home from a trip pulling our fifth wheel 250 miles to our usual camp spot, we smelled coolant burning. We stopped and found it slightly wet at the degas cap and along the side. Bought a new cap at NAPA, started off, and it smelled worse! A turbo whine too for about 1-2 miles.
Got home, replaced the whole degas bottle thinking perhaps a new cap, put the pressure on a seal in the bottle or something, took the trailer back out -- 15 miles from home there is the smell again while pulling the trailer. We don't see any white smoke, no green moisture in the exhaust, no coolant in the oil. We only have standard Ford gauges -- dummy gauges so they only go so high and stop -- no over-eating or red light/service indicator coming on. Minimal loss to coolant (not even really detectable except for the obvvious smell).
I thought the mods we did could only make things better -- Volant intake, MBRP 5" turbo back exhaust, MagHytek diff cover and tranny pan. We have no tuners, no programmors, no chips, just trying to help it stay "cooler" under load.
I'm concerned about putting in at the dealership for fear it will become one of their usual hunting expeditions -- on my nickel this time and Las Vegas in general is not the most reputable kind of place to have work done. We totally trust the performance shop who did our upgrades, but I don't think they are really set up to diagnose this problem.
Can anybody recommend good honest 6.0 diesel mechanic in Las Vegas?
Or, at least, what should I make sure they are checking when I bring it in to the dealer?
Radiator?
EGR cooler?
Head gasket?
Head studs?
Please add/modify the list and add any thoughts -- the only thing I feel I can do now, is be well-informed.
Please chime in all you Ford guys. I don't want to switch trucks -- I'm down to just a few payments left and don't want to start all over Dodge or Chevy issues.
Sorry if I hijacked this thread, but PLEASE, I NEED HELP!

Add "oil cooler" to your list. My 05 went exactly the same as yours...pulling the fifth wheel I could smell coolant. If the oil cooler caused the EGR cooler to fail, it is very possible with continued use (like I did) that the coolant gets sucked in the intake, and since coolant does not compress like diesel fuel, it ends up stretching the head bolts. I beleive, had my oil cooler been diagnosed properly the first time instead of just replacing the EGR cooler and sending me on my way, that I could have avoided the dreaded head gasket fiasco. Others may disagree and say that the damage is done to the head bolts immediatly after the EGR cooler fails.
If your head is cracked you should see evidence on your head gasket. If your head bolts are stretching you should see evidence on your head gasket. Basically, if it's a head or gasket issue, it should appear on your head gaskets.
