AP, no haven't looked at one yet. The duramax's are pretty few and far between, and when you do find them, usually a bit out of my price range or farther than I want to drive.

Keep walking, once they are close to or out of warranty and people start getting rid of them be very wary.

 

Thought I would let you know I just lost another injector on my 143K LBZ and am stranded in Co

 

Thats very out of the ordinary, you sure there isnt something else going on? My old truck has over 120K on it now and is running just fine right now. I hardly ever read problems with injectors on lbzs over on dieselplace.

 

For some reason the un common allways happens to me..... I had an LB7 that I had to replace about everything but the injectors. And an LLY that kep sticking thermostats open and running too cool lol.

The truck was a fleet vehical from TX, and my buddy that lives down there said some companies down there use really bad fuel. The injectors that I took out were really nasty looking, compaired to others I have seen. I was thinking maybe the CP3 was failing and putting shavings through the injectors, but it runns like a raped ape and holds good rail psi.

 

Yeah those are quite wierd, and LLY that runs too cold

Might not be a bad idea to pull all the injectors and get em cleaned and flowed, might save some heartache and a piston later on...

I miss the hell out of my truck thats for damn sure, just have no money with going back to school full time next semester

 

I know the feeling. I had to sell my 07 GMC LBZ classic back when times got tuff I bought it new only had 19,000 miles on it when I sold. I loved that truck. As for the injectors I poured a gallon of marvels mystery oil into a 1/4 tank of fuel and bested the **** out of it. Seems to be running alot better and is bairly knocking now. I think I have been babing it too much, I was scaired to get on it because of the miles.

 

Well it lost another injector yesterday. I ended up pulling the tank looking for water, or a bunch of crap in the fuel but was rewarded with a clean tank, with a metalic aluminum coating along the bottom. Further testing leads to a failing injection pump. This means the pump, rails, and injectors are all going to have to be replaced. This is a 7~$8000 repair if I buy everything new. Right now I just want to set this piece of **** on fire, and push it off a cliff.

 

damn, threads like this scare me cause ill have to pay for labor aswell...
