Default instant low oil, engine noise, drivetrain noise, help!

So, I normally check my oil around every week, especially lately since im past 4k miles and still waiting to get the oil changed... I drive out to this place a few miles away, the bowl, with no problems, the car drives great and sounds fine... I start up the car a little later, the water temp is all the way down, I take it pretty easy, but I can't say I didn't get any boost before it was fully warmed up, nothing more than 4k though, just passing etc. (this wouldn't be the first time... being late for school+really cold outside=bad) So I leave to go get some food, come back to the bowl, and stay for a while. Then I go back out for food again, the car is cold on the start again, as i'm leaving, I notice that whenever I slow down (coasting with the car in gear - not using brakes) the car makes more whirring-gear-lash type noise, so since food was really close, I took it extremely easy on the way there, and checked oil when I got there. There was barely a drop on the end of the dipstick... whoa! So I get back to the bowl, I put roughly 2 quarts in, and the oil on the dipstick is up to full after the car sat for a while. I looked around the car and saw that there was black stuff, looked like carbon deposit stuff, all over the inside of the exhaust tip, just a light coat that wiped off on my finger, I showed a friend and he mentioned that he thought he saw a little bit of smoke while I started my car the day before... I take the car for a slow drive around the block with a buddy to see *** is up, and the noise is still there, it was hard to pinpoint the noise, sounds like its on the right side of me, but also sounds like its from the engine bay, sounds like it could be motor/drivetrain, and only occurs while in gear and slowing down by coasting. ***... then I see some wet oil on the exhaust tip, and after the engine is off exhaust/vapor/smoke still comes out, It's too dark to tell what it is... So maybe I put a little too much oil in? or maybe its leaking... Finally I leave to come home, and while on a highway going 60 ish, I put it into neutral and coast, while im coasting I hear a nasty sounding whine/gearlash noise from the rear right of the car, like 99% positive its from the rear right wheel area, and the noise varies with the speed of the car, so it must be the drivetrain. Also on the way home, I noticed that whenever the car jerked the slightest bit, if you barely mismatch the revs and let the clutch out, there is a knocking sound coming from the same area, rear right. Only thing I can think of that could have caused this is my driveway, my friends driveway, and the bowls driveway are all dirt/rock with uber potholes... What could all this be from?? so far the only thing I can think of is that too much boost in cold engine temps borked a gasket or the turbo and it is leaking oil through the exhaust, and that maybe the other noise is a wheel bearing or something? Only mods are snow tires... 225 dunlop m3's on 17s... Thanks

yeah its possible your turbo is leaking oil, but i think it would be really noticeable. In other words a total smoke screen behind you that could cover a freeway in both directions..sound like I know???....it happened to me in a previous car....turbo seals took a crap, and I smoked out all of highway 99 here in Cali.

well thats a little relieving, I was skeptical of that because the turbo still sounds normal and seems to work fine, but I still dont like the lost oil and carbon in the exhaust

hmm, after searching I think it might be the wheel bearing... below 30-40mph, I dont get any noise except while coasting in gear, and it just sounds like a little extra trans gear lash, but from a different area, cant pinpoint it... but I have a clunk whenever the car jerks the slightest bit, and whine that gets pretty loud at speed.... what you guys think?

Just jacked up the right side rear, not much play up/down or side/side, but with the rear left on the ground with a block behind it, ebrake off, the right rear tire rotates about 2 degrees or so, and I can hear a noticeable tick from the differential area, a subtle ding-dong when you move the wheel forwards, ding, backwards, dong, sounds almost like someone is knocking on part of the car's body, and the noise is louder when you spin the wheel backwards, so im thinking thats the clunking noise whenever the car jerks, it would occur when the wheel slows down, which is kinda the same as moving the wheel backwards when the drivetrain isn't moving.... hmm, could this be the clunk or is it just normal gear lash?

bump bump...

put stock wheels back on, test drove it again, clunking whenever the car jerks the slightest bit, sometimes even on smooth shifts, coming from the right rear, at 30 mph there is a little whine from the right rear, and from 40mph-60mph there is a nasty groaning that follows the speed of the car... no more oil on the exhaust, and motor sounds okay..
