There are other ways for an inj. to fail that does not fall under guidelines, such as inj. leaking from tip or stopped up . In these cases the SES may or may not come on. Also only certain codes are covered. I just put 4 i***. in drivers side for a guy that were not covered. One inj.had high balance rate (+12 mm3)& did not affect return rate or rail pressure. GM is verifying inj. for high return flow rate. If you don't meet criteria , you pay. Otherwise we could be charged back.
Thanks to everyone who voted in this poll.

The results are certainly interesting, but I'm surprised so many people think a set of these injectors could be replaced for less than $1K. The labor alone would be a big chunk of that amount.
I predict that eventually, LB7 injectors will become available through diesel injection service companies. Once that happens, prices could fall dramatically. Also, many owners with an out of warranty engine might be willing to do the R&R themselves. Then, it'll likely be doable for under $1K.
New replacement and performance nozzle components are already available through the aftermarket. We'll be discussing some of these in the upcoming 2004 Rendezvous coverage.
Thanks again,

I voted for the 1k to 2k figure figuring on the labor. I however noticed the votes for the less than 1k too. Depending how you read it, I'm wondering if some thought it was the cost of a set of replacements vs. the cost of a set of replacements, replaced.

I was thinking $2000 for the whole job myself at around a 100k - 150k mile interval. From my perspective, that would be acceptable. When we start talking $4K to $5K, that is starting to become a serious repair bill. At that point, you might be better off trading the truck for a new one.
Another aspect the LB7 design is once you pay the price for the service tech to open the cylinder bank up to replace a bad injector, you might as well get the other 3 on that same side. The labor at this point cannot cost that much more.
In my opinion, the key in all this is to get the cost of the injector way down. GM needs to minimize the interal GM organization mark-ups. This would go a long way on restraining costs. IT WOULD BE REALLY INTERESTING TO KNOW THE ACTUAL COST GM PAYS BOSCH FOR ONE INJECTOR.
You're seriously scaring me now. I have 47,000 miles on my great looking '01, no injector problems so far, but...
1.) GM did hype this as a 200,000 mile motor.
2.) The dual mass flywheel problem did happen a month ago. They advised against repair at that time, that GM engineering was working on a fix.
I'm losing faith. I may unload the truck and GM forever.
