Yep, all 3 of my LB7s that have had injector problems, got the nice anti-rust undercoating

If it's still under the 200k warrenty for the injectors, dump a gallon of diesel into the crankcase and take it to the dealer.....

Dealer said no go.
According to my dealer, GM will no longer replace injectors for just smoking. The numbers have to meet their criteria. Even if the injectors are failing, they have to be "defective" not just worn out, which is usually the problem. The fuel pressure is so high, they explained, that they're wearing out in about 50,000 miles. This does not qualify as a defect. Good luck.
