'01 DMax...The best DSL I've owned...'till now.At 96K trouble started with injectors. Local dealer replaced two. Soon as I picked up the truck, I noticed what sounded like a low rod knock and lifter tick. I was on the road and two diff GM dealers said it was "OK". Now the noise is worse and it's past the warranty (102K). I would like to keep the truck but I'm leary of on the road trouble. From what I've read here, it could cost about 5-8K to have it repaired. What really burns me is the noise, I bought the rig for the quietness of the DSL. Now it sounds like my old Power Stroke. My question is this: Should I replace the injectors (if it is the injectors making the noise) and keep the truck or trade for a new DMax? I really like the truck.
