ewilly Report post Posted May 23, 2020 All of the sudden I have what appears to be the chronic 2003 LB7 injector failure issue. I noticed an excess noise and smoke at idle and then loss of power. I could use some recommendations for how others have approached this problem to avoid being gouged at shops. I am willing to dive in and do the work myself if I can find good parts.

Boarman03 Report post Posted May 23, 2020 My buddy had his done as a recall since it was the first time. Might be worth checking into. I have the truck now and loving it. Share this post Link to post Share on other sites
Delw Report post Posted May 23, 2020 The recall was kinda secret and kept very quiet to most. we took our 2004 in for an oil change and a valve cover gasket leak and the service manager called us and said hey were changing injectors and the instrument cluster due to a recall. mine was 3-5 years past the recall also. I got lucky and it was free of charge I guess cause I knew the service manager. I think we brought ours in back in 2015 when it got changed Share this post Link to post Share on other sites
Boarman03 Report post Posted May 23, 2020 My buddy/ my 2001 was done a little earlier than 2015. Still would not hurt to try. It was a known problem and may depend on the mileage. Worth a good fight. Share this post Link to post Share on other sites
ewilly Report post Posted May 23, 2020 Thanks guys - I will try that although the guy I got it from had told the me it was done already once but after researching they are very problematic. Share this post Link to post Share on other sites
Curtis Reed Report post Posted May 24, 2020 The LB7 would have gone down as one of the best diesels if it wasn’t for that injector issue. Share this post Link to post Share on other sites

Yes and a Duramax is a b**** to work on. Most mechanics hate working on them. Hope you get it all figured out. Share this post Link to post Share on other sites
Cahunter805 Report post Posted May 24, 2020 The Duramax is a great motor. If you plan to keep it or anyone else with one I would highly recommend this filter kit. Much better than factory filters and will help your injectors out. The CAT filter is much smaller microns than a factory filter. http://nicktane.com/index.php/product/filter-adapter-bundle-kit/ Share this post Link to post Share on other sites

Our filter housing cracked and was leaking. 2 Share this post Link to post Share on other sites
