Some peoples' kids (Duramax owners).
I thought you guys might enjoy this. I am doing a set of injectors on an 04 LB7 Duramax for black smoke puffs at idle and a bit of combustion knock.
This is something that I just find really funny. "Hey, y'all! Let's put a 3.5" straight-through muffler on this Duramax to get rid of the restrictive muffler. THEN, we'll bend up this piece of 2.5 pipe to connect it to the original 3.5" tailpipe!"

 And I bet they were still saying their truck was the fastest thing on Earth.

Ugh.
This set of injectors is the most "nightmare-ish" set I've ever done. I spent two hours just removing the even bank (driver's side); and that's after I already had the valve cover off. The nozzles were so carbon-ed up that I spent about 20-30 minutes on each one working them out little by little. I had one on the odd bank come out with the injector sleeve, so I had to reseal and reinstall that one (draining most of the coolant into the cylinder and on the floor in the process....I hate that). That's only the second one that I've ever had the sleeve come out (out of the dozens I've done) but it's not a big deal to reseal them. It just takes a 24 hour cure time for the loctite where it seals into the combustion chamber. I was a good bit tired after bending over that long on my knees, so I called it quits at 10:30 last night. I should have it running again later this afternoon. I still have to run to town and use my friend's sand blasting cabinet to clean the corrosion off of the injector feed lines.

Those duramaxes take a little bit of money when those injectors are changed.....

Well, it's getting towed to a dealership. Stupid people driving on bad injectors for a year and the carbon that is created on the nozzle.....
 I disrupted the loctite seal at the combustion chamber on at least one more injector and I don't have the puller tool. I'm not about to tear into that again and risk screwing up a cup with some hillbilly ingenuity. Looks like I did the next guy a huge favor....those injectors will pop right out this time! Oh well, not like I'm out anything except a few hours. Nothing else was waiting in line anyway.
