Stumped on headgaskets
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?
It spends a lot of time on the rollback
2004 6.0 F350 FX
AFE cold-air intake
Sinister EGR delete
Dieselsite coolant filter
6.4 Banjo Bolts
junk gold coolant
2 FICM (one replaced before I purchased)
some little transmission part (easy $16 fix)
IRP valve & HPOP
gasket on turbo
degas cap (easy fix $4)
no doubt there will be more to come...it is a 6.0
