What do you all think?

Alright, not to start up another HG thread, but I am curious as to if I am just paranoid or not.

I was looking through threads on here one day and noticed a video someone posted of bubbles in the degas bottle. Well curiosity got the best of me and I decided to take a flashlight out to my degas bottle at idle after driving for a 20 mile trip...I also noticed some bubbles coming from the bottom hose on the degas. It was not steady and the bubbles were large...went bubble bubble, then about 3-5 seconds later another bubble bubble. The video on here the guy had about the same size bubbles, but his stream was much more consistent. I have no puking at all and my level has stayed very consistent (no loss noted). I have noticed from time to time that when I get hard on it and then let off I will hear a small squeak type noise (tea kettle?). For what its worth, I had a bad CAC boot at the turbo which I replaced, but I do notice the CAC boot to the aftercooler is shot (oil coated and oil blowby).

I have no other HG issues...heater blows super hot, power seems good, no coolant smell, oil looks good, no oil in coolant, no puking, deltas are always with 8 degrees even when pushing it hard.

Oh, and I checked today after making the same 20 mile trip I checked the bottle at idle and saw no bubbles

What are your opinions?

I would say that was just air working it's way out,whether some trapped somwhere in the system or air generated by pump cavitation who knows.

The 6.0's were discovered to hold trapped air for a long while. So much so that a tool and procedure were developed to pull a vacum on the cooling system and suck the coolant into the system. Much like rechargeing the a/c system.

hmmm that might be a thought, I changed the thermostat, but that was back in December, I don't suppose there would still be air in it from then. I do plan to make a pressure tester like many use on here to test system pressure.

okay, update. This morning on my home from work (7-10 mile drive around 40mph) the truck started making the whistle while not really getting on it hard at all...when I got home I popped the hood and checked the degas...found it bubbling a lot. ECT was at 184 after sitting in the driveway for 2-3 minutes (was at the normal 190ish after complete warmup on the drive home). Now I am completely confused...

Well, I'm really thinking it is HGs...guess I'll be taking it somewhere to find out for sure

I have an over the phone quote for $3700 with parts, OEM gaskets, heads magnafluxed/inspected and machined flat, EGR delete. Sound reasonable? Put up an ad for some Class 3 toys I have to fund the fix...stupid truck

most people would say to put a new degass cap on it first....it is an upgraded part now. then monitor the conditions.

Well...its official, HGs are toasted, goes under the knife next week
