That fitting cost me around $60cdn from cummins in alberta to.

 

I just stated that since for the earlier trucks they use #1 injector signal to start. On many of the 03-04 trucks with a bad #1 injector they will give hard or no start conditions. As for the rail cap..miller tools sells it as does cummins and 60 dollars is about right.

But if you can disconnect one injector at a time I would do that and save the 60 dollars. Just do one by one and see how the engine reacts. You will see all sorts of DTC's when you do and for evey injector you shut down, there should be a 75-80 rpm drop.

 

Your are going to have to pull the head anyway.....once you do that you will see the problem...the sound is twice as fast as the valve train so it has to be oiston problems,,,watch the video and count

 

Any news / insites ? God, bad ?

 

Pulled head last night, #6 piston was scuffing the wall, the top of it had started to disitergrate and pieces had broken off which then beat up the BRAND NEW HEAD!!!

I picked up a low milage SO engine just now, hope to have the truck running by Tuesday evening.

 

Great !....How ever,, could you past a pic of the deceased head ( valve area ?
Sorry to hear you confirm that............nasty nu 6.

 

What are you? Some sort of sick physco that likes to look at pics of dead things and revels in others misery?!?!?


I'll see what I can do..........

 

Here are some pics of the HO with the head off and SO in the back of the truck. Sorry the pics are crappy, camera died as I was taking them.

 

Is that actual dents and nicks in the head ? or deposits of Aluninum ?

 

Yes, it look like someone beat it with a small ball peen hammer, no deposits of aluminum.

 

Wow the piston must B in 10000 of Pcs ?
When you get the time......pull the pan and see what if anything is lurking there.....

 

Pan is off, nothing was in there.

 

Did that fail under load ?? looks like heat build ( soaked ) to sag in the middle like that

 

well at least you found the problem. don't want to blow my own horn but my gut just told me it was a piston problem. I'm sure you know this but make sure you look at the tip of number six injector to make sure it's not all beat up too. Most likely is. Check the turbo aslo those pieces went some were. Hope you get it running soon.
