3406b running rough

Working

 

yes spoke with mechanic, which I was there helping threw entire process he says he must have just forgot to tighten the jam nut and I never payed that close attention when we were at that step. I have tried getting a service manual and ended up buying a online one for $60 it has a lot of info but can't search anything you just have to scroll threw all 5000 pages tell you find what your after, very time consuming. He doesn't want to work weekends so I have another guy I know coming in morning to help me check everything and put that rocker and push rod back together only problem is he isn't a diesel guy but knows gas engines very well so figured at least be able to get those valves adjusted and recheck others. This project has been a s*** show never planned on tearing it apart myself but that's how the dice rolled, huge learning curve.

 

I think that is probabaly a good idea before starting it. When we originally started it up it had a terrible noise coming from valve cover and went away, mechanic didn't say anything and just wrote it off since it went away that must have been what it was. How it came apart that fast is weird tho.

 

Update on what I have done.

Got #6 push rod back into place and valve adjusted. Rechecked clearances on remaining valves and checked to make sure adjustment nuts were all tight so wouldn't happen again. Fired it up and ran a lot better was very Smokey for a bit and took it on test run and cleared burning clean. Truck seems to be running good. But when I crack #1 injector line it still does not change the way motor runs like other 5 do. Got truck up to operating temp and put a heat gun to exhaust manifold and checked all 6 in as close to same location as I could. #1 was running around 150 degrees and the rest were all around 300. I didn't swap injectors wanted to get #6 back together and do one step at a time. So am I looking at possible injector or just a dead hole? Think I may just go fork out the $120 and put a new one in #1 and see if it changed anything

hats what I'm leaning toward was going to swap #1 to another hole and see if problem changes position but then pulling it apart 2 times vs 1 if I just buy another. Granted all 6 are new and just installed
