Well, I'm not a tech, but I waited a day and no replies yet so, I'll bump it and give you my opinion.
Was the sound a squealing sound? Or a huffing sound?
If squealing, I would say the turbo is going out. If huffing, maybe just a split air charge hose (hose coming from the turbo to the intake)
Either could cause the black smoke due to loss of boost.

I concur with bpounds on the turbo starting to take a dump. The reason I don't think it is a split hose is that it would not come and go. A split hose would leak under the smallest boost of the turbo. I too am not a tech, just my uneducated guess. That and 4 bucks gets you a beer.

Good point. Although the noise might come and go, depending on how much boost flow was blowing through the leak.

Some of the earlier blue hoses will weep oil thru the rubbers pores. I had 4 of them replaced under warranty for weeping oil.

A good way to make sure its not the hoses is to remove them, clean both the hoses and the Intercooler and pipes with brake cleaner and then reinstall them. Make sure that you do not over torque the clamps or you will ruin them. I too would agree though that if it were a split hoses or damaged CAC it would do it all the time. More than likely the turbo is over boosting or underboosting. Do you have a boost guage installed by any chance...if so what were your boost readings, also did the check engine light ever come on? if so did you check what codes were stored.

I agree with bpounds. Thats why I asked if he could see the boost numbers and if the CEL came on. I know on the 05-07 you will get an underboost code when infact the truck is overboosting.
