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.

Check the plugs to see if they are oil fouling, it sounds like the turbo seals like you said. But the low coolent doesn't sound good. Has it been low, have you checked it , or was it neglected? Fill it up, pressure test the cooling system for leaks. You can get a pressur tester in a parts place, kind of looks like an air pump. Start there.

i actually flushed the coolant system about a week ago, and filled it with just water cause i didn't have any coolant available at the time. I just put new plugs in about 2 months ago so it could be that they are fouled but im not sure. The ic pipes smell strongly of gas from running rich, my guess is from the atmospheric bov i have. But yeah i will try and check the cooling system and see if its holding pressure

alright guys i took some pics of the poolin on the turbo, im beginning to think my turbo is just fuked up.

it seems as though oil is just exploding out somewhere, but the lines seem to be dry. only exception is the oil is running down somewhere onto the block and dripping off. It could be possibly that one of the lines has a crack in it and it spraying up but i dont think so. What the hell is going on

i was told it could be a clogged pcv valve.. but i dont know how to test that. Also, i started it up this morning and it was idling and revving fine up untill it reached operating temp and then you could hear it start to choke out and idle choppy.
