It is over the years. This special policy is done. It is worth talking to the dealer but you or anyone else would be extremely lucky to get the injectors covered

another one bites the dust...

'02 Chev 2500HD 128k miles, making oil like nobody's business, bllowing out the breather tube...should've had the injectors done when I bought it in '08... hindsight=2020... oh well... Gonna take it in to Haselwood in Bremerton, WA and see if I can swing some sort of deal...
Any suggestions on what I should ask for?
I plan on requesting: balance and return rates, supply and return pressure hold, Bosch reman replacements and amsoil (I'll supply).
Anything else??

So I have a problem with my 2003 lb7. I just changed fuel filter and now when pulling a grade or getting into the throttle from about half way my truck getting a clatter and loss of power. Let off on the pedal it goes away as long as I don't push it. Then it shuts off going down the road. So thought I was sucking air so I did the filter again and orings on filter housing and it went away got all power back and no shutting down for about a week. Well now it's doing the same thing. Any ideas would be appreciated I'm new to the diesel ownership.

LB7 replacement injectors

Can anyone give me an estimate on what the life expectancy is on the updated LB7 injectors? My original injectors are finally giving out at 116K with an estimated 6000K bill at the dealer. Is it wise to replace the injector pump while I'm at it? Any info would be a great help.

Sounds like a CP3 not giving enough pressure....

Life expectancy on LB7 injectors is all over the board... Some people are getting 200k+ out of them, others 34-40k. With clean fresh diesel and good filtration I would think you should get at least 75k out of them.... I did mone last year when I bought my truck, I have put 34k on them since, and my balance rates are still +/- 1. 6k seems to high for a injector job. Find a reputable diesel shop near you, I had the dmax streo do mine, I wanna say it was right around 4k...
