Stumped on headgaskets

[Shotgun_girl]

Hey guys, I need advice and/or help, my truck has been running great, still is. It's been a while since I've had any issues.
Problem(s) I've been having are slight puking out of the degas bottle on a hard WOT run (has done this for the 2 years I've owned it), but it has seemed to settle itself as of lately.

I've had a slight notion that my head gaskets are going south...I've developed a hiss that seems to be hitting the firewall on the passenger side about glove box level and we can't figure out what it is. In addition to that, I put a new degas bottle cap on, tested it and it held 16 lbs, we put a pressure tester on the degas bottle and it held 10 pounds, when I would power brake it, the gauge climbed up to about 13. We also tested from 0 psi in the cooling system...at 17 psi boost on a brake torque it went to 3 psi coolant pressure.

Are my hg's going south?? Always starts great, no miss...runs right at 190 degrees ECT, and OT. Never gets hot while towing, I have awesome deltas,...etc....any ideas on where to go from here?

Headgaskets are on their way out. Probably aren't too bad yet but if its puking p
Out of the degas bottle and you changed the cap and the egr is gone then that's your problem. Mine did the same thing before I studded it. One night I was beating on it pretty hard and it puked out all over the battery and fender liner. I drove it for a few weeks after that and it never did it again but I didn't beat on it either. When I had the cab off and studded it the gaskets were blown. Not bad like some I have come in the shop but they were blown.

Oh and the hissing noise.... Did you look at the bellow on the passenger side up pipe? Had one the other day that didn't look broke but when I pulled the up pipes out it fell in 2 pieces!

Sounds like your gaskets are gone. You shouldn't build pressure that quick. It's all a matter of how fast the needle moves at a WOT run.

Visually looked and no signs of soot.

I will build a setup to watch it at WOT

I'd knew my connotations of sarcasm would be taken seriously on the 'org

Can't see post count or signature on mobile, hard to weed out the sarcasm
