Hello, I have a 2002 LB7, with 143,000 miles on the truck’s odometer. The dealership replaced the injectors the first time at 80,000 miles (under warranty) with (I’m assuming) remanufactured injectors. Now after another 50k I’m getting black smoke at the tailpipe at idle. No increase in oil level, or fuel smell in oil.

Anyway, here are my questions: 1) I was told that I could buy some time before injector replacement by using additional additives. The recommendation was to use Hot Shot Diesel Extreme. Any better ideas, or will additives at this point do anything? 2) I’d like to do the injector replacement myself, but need info on special tools for injector and cup removal and whether it’s necessary to remove injector cups, or not…

Appreciate any help you can provide…
