Hello all. I am looking at getting a used 08 6.6 as my first diesel. The truck has 60k and what appears to be a clean carfax report. Took it for a test drive and it ran great. It is "Certified" so it will have a 12 month, 12k warranty with it as well as the remainder of the 5/100k warranty. Here is my concerns. I have been reading some of the posts on here and some of them scare the heck out of me. It appears that the biggest issues with the 6.6 LMM's are the injectors, or so it would seem. What are the biggest issues with the LMM's, if any. I can't afford to buy the truck and then in 10k or so have to have the injectors replaced and be concerned that GM won't honor their own warranties. I am not planning on doing anything, performance wise, with it until the warranties are expired then only to increase the fuel mileage which I hear sucks. Any comments, suggestions, recommendations regarding my concerns will be greatly appeciated. I also see that I am about 20 miles from Huskerdiesel and will also ask for their advice this week....Thanks in advance. "Mac"
