yeah i was really hoping it was just injector knock. sucks i had to spend $2500 to find out it wasnt. But on the bright side now when i do get my engine all rebuilt i already have my performance injectors and nozzles

here are the pics from the teardown and install
Teardown
NEW PARTS
Re-installation
---AutoMerged DoublePost---
after i got everything torqued back down to spec and everything good to go went and tried to start her but she still wouldnt start. called my local diesel shop and they told me because i had just put in new injectors it could be because there was air where there should be fuel and to just keep trying to start it until it fired up and everything should be fine. i continuously tried, i let the system prime. i got smoke from my stacks a few times but she still wouldnt start. i stopped after trying probably half a dozen times and noticed that some of my fuel lines were wet and the more i tried to start her the worse it got so im guessing there is a clog in one of my fuel lines somewhere and its causing pressure and caused a leak and now its not supplying sufficient fuel for the engine to run. so now ill get to replace my fuel lines and see if she will start and pray that my knock is gone and she runs and everything is good

Time to bring this thread back from the dead..
I finally got my truck back and had the time and money to start my tear down and rebuild (since it wasnt injectors)
i started my teardown and immediately noticed once the valve cover was off that there was an issue
http://s435.photobucket.com/user/Durango_Nick/media/photo11_zps92b4f6a4.jpg.html
i noticed that the front pushrod on the number 1 cylinder was dropping significantly lower than all the other ones.
so when i took the head off completely i found that all my cylinders and pistons were good except number 1
number 1:
others:
and overview:
So I pulled off the oil pan to check the bottom end and see what was going on
then i found this:
Bottom end looked good other than the blown through plug
So my plan of action is to hone all 6 cylinders in put in new rings, put in a new #1 piston and connecting rod, and a new pushrod in place of the one that dropped and was rattling around
My question is what is the plug i found in the oil pan??

Ya just I would just inframe it and replace the rings and number one. I have no idea what that plug it alomost looks like a freeze plug but how did it go from up top past the piston to the oil pan?

i think the plug is from the secondary oil return line hole. must have been left inside after popped in.
if my pushrod is dropping down an inch farther than the others what is underneath it that would be bad?

welllll i went and looked down from the top and checked the valve lifter in the front pushrod hole and it looks exactly like all the other ones so my guess is that isnt the problem..
tomorrow morning i plan on pulling my pistons and the rest of the bottom end out and checking my bearings to see if one is spun
