It finially happened
Well, it happened. My crankcase is full of fuel oil. I have 148K miles on it and it happened Saturday evening. Had it towed to the dealer and he confirmed it's the injectors. No trouble, will be ready tomorrow. Anyone know how long this fix is good for?

Truthfully, the repair is only as good as the technician is as well as the "REMAN" injectors are. I have seen the injectors go as far as 180,000 miles and as little as 8,000 miles.

Not sure if you live in a climate where underhood corrosion is a problem, but if the flare nuts where the high pressure line meets the injector is rusty, I'd ask them to replace the lines as well. They should be covered under warranty, so make sure if they say "YES" to get it written down that it is a warranty part - as the OEM lines from GM are over $800.
My dealership wouldn't cover the lines, so I had them push the truck outside and I bought a set on Ebay, and had them overnighted to the dealer. Cost? About $70 with shipping, IIRC.

As for longevity, I have 50K on the second set in the 2002 and it runs like new.

Possibly another148K miles

The only draw back to your lines Mark is that although the ones you bought off of EBAY are the correct ones, they are not the new and improves lines.

They are made of unobtanium, capable of withstanding a gazillion PSI and will never corrode. That is, of course, if they are installed correctly, properly maintained and kept clean. If you do what you always did, you'll get what you always got. Design is the problem, not the material.

Well, I am still doing what I always did...driving and burning fuel.
Wonder if the material is intended to reduce expansion under high fuel pressures. Recent postings indicate that rail/line expansion affects timing. ECM compensates. Does this mean the LB7 ECM would have to be aware of what lines you have - old style or new?

My 2006 made it to 7000 miles. Real impressive! Furthermore, they would only replace the faulty ones. Not all eight. I thought that was rather unusual

They do all 8 on the LB7 because they are under the valve covers. Yours are outside and can be replaced w/o a major tear down and shop time.Originally Posted by ccole

I got the truck back and it seems to be running fine. It dosen't smoke, it's quieter, and seems to have a little more power. I couldn't believe the dealer didn't flinch about declaring it an injector issue. They replaced all 8 injectors and 3 pipes. Now if it will just hold together.
