lb7 injectors, return rates verses all replacemant
 

if the return rates on like 6 injectors are in spec's, and 2 are out, odviously replace the 2 bad one's. now, the other 6? is there ANY running quallity difference between 6 used injectors in spec, verses replacing the 6 known good one's with 6 new gm reman injectors? so why spend the extra 1200 if your right back to where you were? thoughts?

Just remember that it's a large job and those other 6 injectors have the same amount of wear on them. Stated a different way, if you just replace 2, you'll probably be doing all that work again pretty soon. All depends on how energetic you are I suppose.

Also its almost impossible to remove fuel lines without getting dirt and rust into injectors. Since u have to remove all fuel lines on a bank u might wanna at least do that bank of injectors.

I am getting ready to change the injectors in my '02 Duramax so how long should I expect this job to take me? I've been a mechanic since I was a kid helping my Dad but I've never changed the injectors in any of the Duramax diesels previously.

Thanks

Just had new injectors installed in my 01 druamax, no more haze issues.

Sorry... thought I was responding via PM to remark 10 pages back;"Ford friend says chevy injector swap take 18hrs".

A quick tip to those having trouble with cheapy plastic QD tools...
Hit QDs with break clean first to clean out any crud that might've built up in em and here comes the Knowledge!!!
Like most any QD fitting, air line or what have you What's the first thing ya gotta do to separate the fitting? You have to push both ends together before you can lift the locking collar.
Granted the tool can force them apart but if you just push the lines together while slipping the tool in, it doest have to.
So the cheap plastic ones work smooth as butter
Took me a sec. of :argh:to figure it out too

Cheers
