What makes the injectors go bad in these trucks? Are they hard to remove/install?
keep us informed as it looks like i will be doing the same here pretty quickHello
I am picking apart my enginge now to get to the injectors, looks like the valve cover is two parts. Do I need to remove the lower bolts or the upper ones? Getting my injectors tomorrow so I wantet to take them out so everything would be ready today.
Thanks
I have the same problem. The dealer told me 18 hours of labor and yes I'm pretty sure you have to take both off to get to them here is a step by step post of how too..

I just paid a Chevy dealer $4,570 to replace all 8 in my 02. That included oil change, disposal fee, taxes,etc.How much are 8 inj's???????
From what I have gleaned after owning an 02 for a year and a half, the cause of the bad injectors is a faulty design on GM's part, which is why they came out with the recall. Others can interject their thoughts here also (but it is my understanding that the injectors usually go bad on the Duramax's around 150,000 miles with normal usage). I also hear that certain things can extend the life of the injectors, or decreasing the chance of failure, like lift pumps "more specifically not getting into a situation where your fuel pressure is low at the injectors", running fual addatives that lubricate the injectors and things like this.What makes the injectors go bad in these trucks?

If you are looking for the symptoms of injectors going bad I think there are two main ones, most common seems to be fuel in the crank case, and I think ankother one is excessive smoke from the exhaust. Again, hopefully some of the other guys on here can weight in on this because a lot of them have much more experience than I but hopefully this helps out.
Good Luck, and you will LOVE your DM
AND..... Labor Unions...Now you know why GM went belly up, desicions like that.
I have 180,000 miles on my DMax and I'm still running factory injectors. I add a can of Sea Foam to clean the injectors every 4 or 5 tanks, which you should do with any diesel. I also change my fuel filter every 4,000 - 6,000 miles.From what I have gleaned after owning an 02 for a year and a half, the cause of the bad injectors is a faulty design on GM's part, which is why they came out with the recall.
