I was talking to another Duramax owner and he stated that it was common for the injectors to have problems around 40K. He knew several people that had this problem. Is this antidotal or is this something that I should expect in the future? I have looked through the posting and haven't run across this complaint. I would think if this is a common problem it would be talked about. Thanks for any info you folks may have.

Thanks,

Richard

Friend is a service manager at a local dealership. According to him, they were having injector trouble with 01/02 motors, problem went down in 03 and with the 04.5LLY injector problems are pretty rare. GM stepped up and increased the injector warranty on the 01-03 to 200,000 miles.

injectors if they fail, do at random. no set mileage, gm trying new filter(dual pleat) to stop. check out injector survey, wide spectrum on miles.

There is a post on here about a brand new LBZ having injector trouble after 810 miles. Your best bet to keep injectors happy will be a fuel additive (GM recommends Stanadyne (http://www.gmdieseltech.com/store2/cart.php?target=product&action=view&product_id=16300&category_id=298)) and a secondary 2 micron fuel filter (Raycor (http://www.lubricationspecialist.com/index.php?cPath=24_32) or Nicktane (http://www.nicktane.com/filter.htm)). There is no guarantee you will not have an injector problem after these "fixes". It is good practice and could save you some trouble in the end. You can also visit Kennedy's website (http://dieselplace.com/forum/forumdisplay.php?f=105). He sells his own filter kit (http://www.kennedydiesel.com/categoryresults3.cfm?Category=3&SubCategory=108&SubCategory2=87) and highly recommends FPPF fuel treatment (http://www.kennedydiesel.com/categoryresults.cfm?Category=9).

I am hoping that by using biodiesel at 20% it will help avoid injector problems. The lubricity is supposed to be great.
