Totally confused and frustrated please help with smoke problem

2006 ford f250 6.0 diesel 102,345 miles
Truck was running bad when it was cold. Then would run pretty good when it was warm. And never ever smoked. Took it to ford try said I had 2 intermittent injectors and 2 down injectors when the truck was cold. So I put 4 new injectors in it. Picked it up an it ran excellent. But would blow whitish colored smoke every time you would stop at a stop sign then take off. So I took it back to ford and they claimed it had 2 more down ingectors. So I said screw it replace the other 4 injectors. So picked it up today an gues what still runs good but also still blows white smoke when u stop and go. Took it back and they said they don't know what to do. So any idea of what it is or why it only smokes at stop and go ??? It has no programmer, it has no cat, and it has egr delete. The smoke is definelty oil or diesel not coolant. I don't know what to do ??? Or what to fix??

Check your oil level closely and also smell it for diesel, if you have a bad injector fuel can wind up in crankcase.
How does the exhaust smell?
Put you finger into tailpipe and see if you have oil in it. If you can take apart pipe where cat was look in there for oil.

Bottom line, sounds like either a injector or the turbo seal leaking.
One other thing you can check is pull oil fill cap while running and check for blow by?

oil level is perfect and always has been, before all this had happened, I changed oil, oil filter, and both fuel filters.
stuck finger in pipe comes out black, but not wet,
and have taken oil cap off no blow by ever, not when it is hot or cold, so its just weird that it did not smoke before i took it, then they replaced the first 4 injectors and then it smoked, they said needed 2 more injectors, so i replaced all four and still smokes, tells me that something is wrong the first set of 4 injectors, what do you think?

Yea my thought would be a o-ring leaking on a injector, if you were having a fuel problem I would think it would be a liitle on the rough side ?

that is exactly what i think also,
well ford is getting it back tomorrow, wish I would have never taken it there. now they have me by the balls, i am making them replace the first set of 4 injectors because that is when the problem happened.
but proving the mechanic wrong is going to piss him off, but i dont have a choice, i just want it fixed correctly.

Myself and another member of my group had a similar problem with this. My issue turned out to be turbo related. The other member is still trying to figure this out on his truck - I'll let him know about your dilemma, he's a mechanic - so maybe he can shed some light on this for you.

A bit ironic it started smoking after first 4 injectors were installed?

With that being said look at how many posts we see running bad after changing oil or wont start after oil change. It could be unrelated but not so sure, why dont they give him a explanation of why it is smoking now? Little strange

Ah, I see... I forgot that it never smoked before the first 4 injectors were replaced.

Go in there with a calm nature and just explain to them it ran rough cold, it didn't smoke and your recomendation was replace 2 injectors and you opted all of them on the bank.

Tell them the truth and be sincere, ask them about the possibilities of a leaking o-ring with the first four injectors. They will take care of it, myself I would not be sorry at all for taking it to the dealer. I think most often is the best place to have work done
