odd SR problems

[trybal]

Alright guys im really in a hole right now about my engine. So it hasn't really given me any problems. every once in awhile when i start it it idles really shaky kinda like its only on 3 cyl but then levels out in a few seconds and is fine. Well today i was driving it for about 2 minutes, not hard at all and it started to shake and smoke started pouring outta the tail pipe. Can't really tell if it was white or blueish white. but alot was coming out

So i drove it a mile back home and got pissed thinking its a blown head gasket. The only sign was the smoke and loss of coolant. Well i let it sit for awhile and got back in and started it up, took awhile but it started and now its driving fine. idling perfectly smooth at a decent 900-1000, and boosts fine. Except it smokes a bit under boost.

One thing that concerns me, there was oil pooled on top of my turbo, but it didn't lookin like it was coming from the lines, it looked either to be seeping through the mani>turbo, or turbo>downpipe gasket. Possibly a blown turbo causing these problems? and yes there is oil in my ic piping..... help

seems like the seals in the turbo might be going out and thats choking up my idle causing the shaky idle and smoke? Or a blown HG. but if it was a blown hg it wouldn't run normal sometimes and not other times would it.

The oil looks fine and besides the low coolant it looks fine too.
