When I asked about the injector pump being warranted for 5 years they told me it wasn't. They also told me that the injectors weren't warranted to 200,000 miles......I am really getting tired of all the BS I have been getting from the dealers.
Good Afternoon,
The bulletin I have is labeled Document ID#1866141

If you have any further questions you can e-mail me directly

Hopefully your trucks claim to fame will not be like mine "88,000 miles and four sets of injectors later!"
Good Luck

You can probably ask your local dealer, and they should have it on hand. If not let me know and I can either E-mail you a copy of it in an adobe file tomorrow or I can fax it to you if you give me a fax number!

you do have injector issues if you find fuel in the crankcase, poor idle, smoking at idle, and for everyones info injectors are covered up to7 yeras & 200k miles for 01-03 LB7's. Another policy supports the same thing but if they even think or see evidence of a tuner no warranty and they will black flag the VIN

Well the saga goes on. GM replaced My injectors with new and improved, gauranteed not to leak into the crankcase. Two days after getting My truck back one of the injectors failed and resulted in a heavy white smoke bellowing from under the hood and of course smelled like deisel fuel. They fixed this with another four day stay at the dealer.
After four months and after the five year warranty had ran out My truck started running very rough, like it was running on 7 cylinders. Back to GM for repair. This time it had a bad valve guide and wasn't allowing one of the four valves in number eight cylinder to not seat, causing it not to have compression. GM said it had nothing to do with the six gallons of deisel I had previously in the crankcase. GM wouldn't replace the guide and agreed to split the cost of replacing the whole head with Me, total cost was just over $3,000 dollars. This engine has four valves per cylinder, thus four valve guides per cylinder an only one failed, waiting on the other side to fail now. Truck was in the shop for three weeks. Two days after getting it back went to start it and it would start and run about ten seconds and then shutdown, like someone had turned the fuel off. Raised the hood and pumped the filter till it wouldn't pump anymore and it started. If the trucks sits for three hours it has to be pumped before it will continue to run. Back to GM, they don't have a clue what is wrong this time, some kind of leak in the fuel system. Still didn't have 100,000 miles on engine.
Very Very unhappy with My Chevrolet Duramax that was supposed to be built "Like A Rock"
