Injector Warranty?

I have an '04 LB7 in the shop right now waiting for a new set of injectors. ;)

I am about 90% sure that my truck has injector issues. I get white smoke (mostly at idle) that makes people gag when they're parked next to me at a stop light. Last and first (I just bought the truck a few months ago) oil change, i noticed that the oil was very runny and smelled of diesel like no other, however it didn't seem like there was really too much oil in it (but I didn't exactly measure how much came out). The smoke really started to bother me so I went to the local dealer and he told me that some of the signs of injector problems were white smoke and fuel in the crankcase. Even though I told him that my truck did that he said that the check engine light would come on if there was an injector problem. I also asked if the injector warranty was extended for my truck and he said it was for the 01-02 but not 03. But I'm hearing that it was, and the way to know is by the vin. Can anybody here tell me if mine is covered? '03 chevy 2500 duramax.

Thanks

Smokester, I'm running on my original injectors at 160,000 on my 02 and just recently noticed some smoke at idle but she hasn't thrown any codes yet. I'm sure hope someone here will let us know what the scoop is with it.

He is not correct on the check engine light question. My truck had the same issues as yours with no check engine lamp and no codes (though mine is a 2001); fuel in the oil, smoke at idle. With a new set of injectors, no fuel in the oil, no smoke.

The warranty is a moving target. At one time all 2001 to 2004 LB7s were covered but that was rolled back to only the 01-02 models. As has been mentioned here, it seems that some dealers are doing courtesy warranties, but the bill is huge, both labor and parts, particularly if you have to do the sleeves, and GM is not in that great of shape, so it is small wonder they are balking at footing the bill. You might try a different dealer to see if they will be willing to do something.

What is my dollar exposure if I was out of warranty and needed all 8 injectors?

Well, I took it back to the same dealer after calling the customer care 800 number and verified that my truck was indeed included in the warranty extension (they said it was under the bulletin that was listed in the beginning of this forum 04039A.)

So, i took it back to the same dealer who previously told me it was not covered and when I mentioned that I talked to customer care and they said it was covered he acted like he knew all along that it was covered "yeah the '01-'03 models are all covered" "but you should have received a bulletin in the mail". "I just haven't seen any '03's come in for injectors. Then he said he wouldn't be able to get to it for about 3-4 weeks and after he gets it in it could take a week or two. Anyway, told the guy to piss off and took it to another dealer in the area who said they'd have it done by Thursday. So here I am one day figuring out how I'm going to pay to put new injectors in my truck and the next day getting them fixed for free, thanks for the info on the forum guys!

Well oneton, I don't know much about mechanics and especially nothing about diesels but from what I hear fuel in the oil is the magical sign, if you have fuel in the oil and smoke then the dealer (if he has a clue which obviously I didn't have any luck with my first one) should assume injector issues. As far as knowing if there is fuel in the oil the only way I knew really was the smell of the oil when I changed it and how runny it was. But if you drain the oil and get more oil out of it than it should hold which I think is 10 quarts (don't quote me on that) that could point to fuel in the oil too (again I don't know much about this crap but that's what I'm hearing. So, if you have those signs then I wouldn't hesitate to take it in cause I don't think its really all that great to run your truck on diluted oil. And the dealer should cover it under that special bulletin.

GOOD LUCK!

Thanks Smokester. I can't say that my truck is making oil but I am keeping a closer eye out for it. I'm in a little different situation when it comes to smelling for fuel in the oil. I have to rely on other people for that because I have absolultely no sence of smell. Strange I know but I can't ever remember being able to. I guess the only real way to find out is to have my oil sent out and tested. I remember guys here sending their oil out but I can't remember the company that they sent it to. Anybody know?
