Any update on this?

Alright, I've been a little busy with life and just got back to the truck a day ago. Since my last post I have not had a chance to pull the injectors out, but I've acquired Autoenginuity w/enhanced ford package. So maybe it'll help. When I plugged it up I set it to look for misfires on the suspected injectors and nothing. I turned off the #6 and #8 injector, not at same time, and there was really no difference and continued to smoke like hell. The FICM is good on volts, and there are no codes. But the injector control pressure is 650 psi @ idle and when I unplug it goes to 870 psi. Does anyone know the correct psi @ 700 rpm idle? And another thing that seemed off was the injector timing, it is -3.58 at idle. Normal? The control pressure regulator is at 25% and the fuel pulse time is 1500.00 usec. If yall have any questions about certain numbers let me know. If everything seems normal then i'll pull the injectors and check o'rings and Cu washers.

heavy white smoke= coolant

I flushed all the coolant during the head change and all of the coolant lines are off while its running. The smoke is not sweet smelling, it smells like diesel. Over fueling at idle could produce tons of white smoke as well. As long as the air to fuel ratio is off.

Probably junk injectors then. ICP sounds normal for at idle.

The only ford injectors I can find are remans, is that all they sell?

Yeah they're all remans, no such thing as new 6.0 injectors anymore...

However, some places definition of "reman" is different than others. For some, like Ford, that's a complete rebuild with new spool valves. For other places, that's slapping new o-rings on the outside and sending it....

That's what I expected but I wanted to make sure before I go and spend $500 on two injectors. Hopefully the other company just screwed me over and its bad injectors, problem solved. Then it'll only be a $300 dollar loss. I should have them installed tonight and I'll post the end results.

You can always try swapping injectors in different holes and see if the problem follows too, that would either tell you it IS indeed the injector, or something else with that specific cylinder.

Anxious to see what you find here...

Did you buy injectors somewhere else first?

After reassembly when it first started I suspected injectors and ordered some from, Injectors and Phones, they stated they were sonic cleaned and bench tested. And I searched for negative comments an found nothing so I went with them mainly because they were $160 ea. Now I know cheap = junk a lot of times but I'm tired of dumping money into truck so was trying to save a little for once. But yea those are the injectors I replaced my factory ones with. (I still have my old ones haven't sent cores back yet)

And I had meant to swap injectors to other cylinders to check for persisting problem, so I'll go ahead an do that real quick. By just trying to find answers ASAP I'm getting ahead of myself.

Well I swapped the injectors around and when I first pulled the injectors out I was sure it was the injectors. They finally showed that they are sealing off so the cup issue is out the window. Anyway the suspected injectors had all kinds of sh#t on the nozzles. So I put em back in and the problem continued but it was at the same ports as if I'd done nothing. But as bad as the injectors looked I still think they're trashed.

Well I went and bought two ford injectors and plan on replacing all of them while I'm at it. So I'll know shortly if it was a bad choice of injectors to begin with.

Well, waste of $600 dollars, it didn't fix the problem. It's mainly on the #6 cylinder so I'm gonna check the fuel rail with air pressure and see if its leaking anywhere. I'm just gonna pressure up everything I can and see if something gives.

I'll probably be done with 6.0s after this is over. I love the look of the powerstroke but this is wearing me out.
