    Turbo spool

    I believe a boost leak is the culprit, when it's making the constant spool noise and I let off I hear it blowing off over towards the passenger side under the hood. I will have to check the intercooler pipes and up pipes to see if they are leaking anywhere. Blowing the lower pass side...

    Turbo spool

    It comes and goes like a faulty sensor almost. Only changes I made were installed a fuel rail plug on the driver side rail and I tore off the insulation on the fire wall and didnt reinstall the turbo heatshield I'm just gonna wrap the a/c line. On the first test drive I did blow the passenger...

I have noticed a constant spool, even under low rpms its seem to be building up boost cause I can see it on my gauge. Never remember the truck doing it before usually with it being vgt...

    Lly headgaskets

    I have replaced all the rubber fuel lines I just bought a big roll of line and replaced them as I go, good or bad they looked dry rotted and I wasnt going through all that work to have a fuel leak later on.

    Does anybody know of a good write up, book, video, etc. for reassembly after installing headgaskets? I had no issues getting the heads on and torqued and setting the valve lash and installing the valve covers but now that I am at all the small stuff like wire harnesses and fuel lines I have...

    Ground cable

    Quick question, does anybody know where the ground cable from the driver side firewall goes? I'm in the process of reassembling my motor after replacing my headgaskets and I cannot remember where it went. This is my first time tearing into a duramax so the reassembly process has been fun, I'm...

I checked around some and when I tried moving the torsion bar crossmember I thought I saw some movement so i took a bar to pry on it and there...
