"Reman Head"... What Would You Do?
I would like to report my progress and whatnot. My truck has been running for almost a week now. Other than the fuel leak here and there, it's in good shape. I ended up getting another head from DHD. After some dealings they 2day aired me another head at their cost. Though I was leery knowing it... -

Symptoms and questions after HG.
The best I can tell, no. The level is the same on the stick every time i check it. When pumping the primer, It seems like I can hear an audible air leak. Though I'm not sure where. -

Symptoms and questions after HG.
Well, the fuel system did not hold prime over night. It held enough to fire. But died a few moments later and I had to pump the primer again. I rebuilt the filter head according to Merchant's video. I doubt that's the culprit. What is the best way to start tracing an air leak? Are there any good... -

Symptoms and questions after HG.
It's all sealed up, externally anyhow. Under the covers, I don't really know. But then again, I don't really suspect anything either. Here's the report: My oil pressure gauge is acting kinda funky. Sometimes it fluctuates with rpms as intended.. Sometimes it doesn't That's the only thing that... -

2003 Duramax Dont Start on own and surges
The regulator is likely the surging culprit. However, I doubt it's the reason it wont fire. -

No start after HG.
They're tight now!! Not leaking at idle.. We'll see how a test run goes. Bumped my damn intercooler intake tube on the pos bat post when pulling it like a dumba$$.. burned a hole right through.. I got it covered for now.. Gonna have to find a tig and weld it up though. -

Lol. How many times have I had to tell people that exact thing. Thanks though! Dave, I remembered that about the SES light after putting as much effort into trying to diagnose it. Been a minute since I was around cars everyday. I did notice my oil pressure didn't fluctuate with rpms as it... -

=\ I pulled the rails with the lines intact. Figured leave well enough alone. I did pull one from #2 cyl to yank the injectors. Seems all the lines on the drivers side are ok (knock on wood). I did clean the injector sides.. Apparently just don't have them tight enough? -

Who said anything about all worked out... This is me we're talking about.. The aftermath is as follows: Truck had a rough idle that seems to have cleared up. No indication on boost gauge. Oil pressure only goes to about 55-60 psi on fresh oil. Oh, and diesel is POURING out from the high... -

Nah, not bad. Just nothing you can pull, replace, and diagnose real quick. I need my truck like 2 weeks ago and my extraordinary patience is diminishing on the tail end of this adventure it seems. -

lol.. My luck. Can't really get to it at the line being under the wiring harness and other goodies they stack on top of the motor. It took me about 45 mins to tear down to the injector port of the line.. Thinking since I tightened the hell out of it I may just reassemble and gamble the time... -

Dmax, should I worry about getting it too tight? Is thread stripping common with these things? I didn't spec torque it, however I feel pretty confident it's at 30ft-lbs. The biggest biatch is that the culprit is the high pressure line beneath the FICM.. These damn things were not built to be... -

So your saying the little bit tighter I got it may have worked? It seems to be leaking out of the boot to the injector and running back and down the valve cover from there. Or I should pull the VC and check that the o ring didn't roll? It was lubed before replacement. I just wonder what would... -

Ok. The fuel leak is at the high pressure line to the injector at the #1 cyl. I could tighten it up a little bit. What I wanna know, do I need to pull the vc and check the o ring on top of the injector? REALLY don't wanna do that. lol.. tired of working on this piece. -

Also, will a variance in demanded fuel rail pressure vs actual fuel rail pressure cause an SES light but not set a code? -

Yea it's another one of those threads. As soon as the ignition is on, I get a SES light, but nothing shows up on my scanner??? I'm pretty sure I have a fuel leak. I'm working to trace that down also. My luck I'm going to get to tear the pass side back down. I'm beginning to feel defeated on this... -

Glow plug cross over and??
I sure can't find the one from the gpc controller to the #8 cyl.. Any pictures? I can't imagine that I would have removed it completely.. -

Glow plug cross over and??
Doing head gaskets... blah blah blah.. Ok, I've found the cross over wire from one glow plug bus to the other, no brainer. However, I cannot find Any wire in the harness or from the glow plug controller that makes either bus live in the first place. Does anyone have a picture of this wire or... -

RTV on coolant bypass?
Got the o ring to fit anyway. It's weird, but I seem to remember it being the same way when I was doing my water pump.. The o ring just seems to be too thin and large in diameter. Press it just right it fits like a glove. I gobbed it up with sil-glyde to give it a bit more surface tension. I''ll...
