Engine oil seals or turbo oil seals?
Anytime I cruise as a steady throttle above ~5,000rpm or higher I get a smoke cloud behind me. Same when I accelerate at WOT in lower gears at approx. ~2,500rpm-4,000rpm. Does this sound more like a Turbo oil seal or an engine oil seal? I dont get much if any smoke on startup, other than a small puff or 2 for the first few seconds, which I assume is normal. My engine has been rebuilt but I have no idea when. ODO has 194,000 on it, so it could be 20,000 miles old or 100,000 miles old. Thanks

I have a stock TMIC, and when I do take it off I ussualy see only very minimal oil mist on it. And yeah Tweak, that might be it, I guess I will see when I get my BNR turbo. If it still smokes, oh well. Drive it till I can afford a rebuild. Little smoke never hurt anyone, except for the mosquitos 
The weird thing is its almost like its on a switch. At say 4,800rpm it will be fine, but then I hit 5,000rpm's and it starts smoking like crazy. Does it under load (in gear driving) or sitting still revving. Which is why I was thinking maybe turbo oil seal, since it seems like it would smoke more under load, but maybe it is pressure related like you say Tweak. Anybody else have a guess or experiance with this?

I have a similar problem, but mine will smoke when it idles below 1400 and smokes when I shift. I have an aggressive street port and my engine was rebuilt about 20,000 miles ago.
I think the smoke is coming from a bad oil seal in my turbo because I found oil in my throttle body and intercooler piping. <--- Does that sound right?

Probably so, unless the oil fairy is trying to confuse you and is pouring oil into your intake at night
