Before I get started with my post and people start questioning my knowledge. I know and understand the duramax motor and the up keep it takes to keep these trucks running in top order. Between my dad and I we have owned 6 duramaxs over the last several years. I traded my 03 LB7 in may to avoid the very common injector issues and bought and 07 classic. Early this week my truck developed a terrible miss on my way home from work. And when i look in my mirror there was a large about of while smoke coming from my truck. :eek: I have seen this from two of our LB7 we previously owned and new right away what had happen but didn't want to believe it. I called the dealer and dropped my truck off the following morning. Recived the phone call from the dealer today. Number 5 and number 8 injectors bad at 17,000. Anyone else having any of the same problem or heard of anyone? I treat every tank with treatment and the truck has had 3 fuel filter changes since I have bought it. Anything can or should have done different to avoid this again?

I questioned the pistons also when I talked with the dealer. Our first lb7 had a major melt down when an injector stuck open, ended up doing a total rebuild. Hope it doesn't come down to this with the LBZ. We will be keeping a close eye on this for sure.
