So, the verdict is one cracked tip, all six were out of tolerence and needed recalibration. They're on the way back, I'll get them Saturday...

Good deal.

Just to follow up on the finished product... I installed my injectors, set the valve lash and the truck is running GREAT! The idle is smoother than I can remember...

Just a few notes: Having the special Cummins tools is important. The barring tool was a big help, I wish I would have had the injector puller and the special tool for the fuel lines (flare nut wrench). The injector tube puller would be a good tool to have too, but I substituted a fuel line connector I had from an old fuel pump.

Clean the engine bay REALLY GOOD before you start pulling stuff apart. Take pictures so you know where everything went (isolators, wires, etc).

I had a folding table that I set next to the truck that I put all of the parts I removed on, I organized them by cylinder so I knew what went where.

When I pulled the injectors, I put blankets in the engine bay so that just the top of the motor was visible... no dropping tools in the engine bay.

When I hooked everything back up electrically, I had some issues. I cleaned the connectors really good with alcohol and an acid brush, the problems went away.

I also changed the oil twice... after I drained the fuel/oil mix, I put fresh oil in, ran it for a few miles, then changed it again. Diesel will do a number on internal parts!

I could go on, any questions, just ask! I feel like anyone with fair mechanical skills can do this as long as you have the correct technical information (which I have and don't mind sharing).

I had this same problem, re-torquing the injector tubes fixed it. Thanks DTR
