Smoking Issue
Hey guys, I have a 2006 F250 6.0l. I'm having a smoking problem that I can't seem to figure out. The smoke is like a whitish blue in color. It happens after I drive the truck for about the length of a football feild. Once the smoking starts it can sometimes be just puffs of smoke when I get on the throttle other times it will fill an entire intersection with a slight haze. I only really notice it when I'm sitting at an intersection. The truck runs great when this is happening. Every now and then I have a little hesitation at the top end of second and third gear when I first start driving but that goes away pretty quick. I changed out the EGR valve and cooler a while ago. And ran archoil in the oil and their fuel treatment in the fuel and that actually stopped the smoking for a while. I'm thinking the injectors are bad but I wanted to get your guy's opinions on this before I have them replaced.

Welcome 
What does smoke smell like? Coolant or fuel.
Are you losing coolant or checked it lately?
Check your oil. Are you making oil? Meaning is there more than what should be? Like a bad injector nozzle stuck open and dumping fuel into the cylinder. If that is the case you can fry a piston head real quick.
Since it smokes at idle an easy check is to unplug injectors one by one until smoking stops. Then you know the problem injector. Some folks say to not do that because you could fry something or get shocked, or the sky will fall. I couldn't afford at the time to pay someone $150+ to tell me which injector it was so I rolled the dice. It worked for me. If the smoke does not stop then you have another problem.
Could be a turbo seal. That could be checked by unclamping the down pipe v-clamp behind the turbo and see if it is dry and sooted or wet and sticky. Dry and sooted is what you want.
Anyway, good luck.

If you're "down" oil then it could be a turbo seal.
There are two outlets and two inlets for the turbo. Air goes into your filter and into the turbo on the compressor side, then out toward the passenger side of the truck into the big metal CAC tube that goes to the intercooler at the front of the truck. It then comes out the intercooler and into another CAC tube (probably plastic for yours) and then back up into the manifold.
The other inlet and outlet are the exhaust side. Air from the motor comes up the y-pipe at the back of the motor and into the turbine side of the turbo. It then goes out the back and down the exhaust pipe.
The CAC tube on the outlet of the upper front of the compressor side will have clean wet oil in there and that is ok.
What you do not want is wet dirty, sooty oil in the exhaust side of the outlet at the turbo going into the exhaust pipe.
Check out page 31 and on in the 6.0 bible: https://www.ford-trucks.com/ford-man...eTableBook.pdf
