Hey folks, let's beat another dead horse!
Perhaps you can help me with my 2004.5 QCLB SLT (100% stock) which I purchased in May 2014. Here is a video I made of the issue as it was in October.
Note that all five episodes shown say "no wait to start" - this means put the key in the hole and turn - not waiting even for the pump. Watch the fifth, and worst example in this video if you are so inclined - this is a common amount of smoke. Heck, while you're at it, why not listen to the sounds and tell me what else you might think?

When I first acquired the truck, it sometimes in the AM would have a very rough idle for about five seconds, then would smooth out and run fine. But it did not smoke! In later June, I took it to the lake during what turned out to be a very wet weekend, drove it on some washboard roads, and while there, I noticed that, because the grid heater would come on, if I cycled the key a couple of times (grid heater twice) the rough idle itself would not occur.
After coming home, and the next AM, it started with a lot of smoking. A lot - perhaps twice as much as the fifth example in the video. Not knowing better, I took it out (rather than shutting it down to investigate, that is) and when I goosed the skinny on the next arterial, I noticed I'd left a huge gray/white cloud behind me.
I thereafter began the fuel treatments - starting with Power Service - I've tried Seafoam in the filter container, new filter (baldwin) - and right now am giving Stanadyne Performance a whirl (mostly for the anti-gel capability). I've perhaps gone through several tanks of Power Service, and a couple with added 2-smoke.
The smoking's down to about what the video shows. One thing, however, is the rough start on idle has been much reduced since this cloud incident - I get a slightly rough start every once in awhile and when that happens, I know I've got a bit more smoke coming out than the other times.
Now that it's been colder, I've observed that when the grid heater is allowed to cycle (because it will) prior to starting, there's no white smoke, just a bit of muddling gray/black that might come out at first. But! That's not always the case. If I cycle the grid heater, and the start is a bit rough, then it smokes. (could be a fuel issue). I've been buying my fuel from brand new stations (new tanks) or Chevron and the like - no crap shops.
One theory I have is that while bouncing on the washboard roads, I shook something loose and it made it through the filter.
One mechanic I showed the video to says that I may not be using the truck enough to allow the water to remain dissolved in the fuel that's in the filter container (it is my new hobby toy I rarely put a load onto that I know will be spendy). He says the smoke may be just water.
I did rent an 8-ton excavator about a week prior to these videos and gave the truck a nice workout hauling it up some hills at WOT. Truck handled it fine. Very little smoke even when it was grunting its hardest.
When I gun the truck, I get a grayish "cloud" if not fully warm, or a slightly visible black trail when its at operating temp - but only if I am sort of gunning it from what I'd guess is a low boost - but if I gun it after the turbo's spooled up, no gray cloud.
Also, oil level is static as is the coolant level. Hasn't changed in the nearly four thousand miles since I bought the truck. I've detected no diesel in the oil. I plan to do a change real soon and get an analysis and put on my fumoto valve.
Perhaps one of you can give me some pointers on what to try - in whatever order. I've read a lot of stuff here about what else could be causing this problem so I'd like to try those first.
Please help - because I just don't have the money for new injectors right now!
Thank you!
