Got my truck back from the dealer last week. They said i had an injector leaking on each side so they replaced all 8. It says inj rem k 3.300 on the printout so i assume they are remanufactured. They said they have had a few customers that get 2 fixed and come back a month later with more leaking so they replaced them all.
Its not very noticeable when they are leaking. A few symptoms mine had were:
1. the oil had a slight odor to it.
2. the truck shifted at a higher rpm than normal in normal driving (loss of power)
3. unexplained drop in fuel mileage( mine went from 18-20 to 15-17)
I wouldn't have even taken it in except my oil analysis showed 3% fuel dilution. The oil level never showed overfull.
If you notice any of these (or other) symptoms you should take it in and have it checked. Its hard to tell.
My dealership was great. They even gave me an extended (4 days)24 hour test drive when i needed a truck.
Our AC also smelled like vinegar so they installed a dryer module kit and added a coil coating aerosol under warranty.
nothing was ever said about my oilguard bypass filter so i don't know if they saw it or not. They even replaced my fuel filter for free(i supplied the filter).
If anyone needs a good dealer in the SW Houston area PM me and I'll tell you where i took it. All in all it was a good experience. They said their diesel mechanic also owns a duramax, so I'm sure he has an interest in them.
