So was driving the car a couple days ago and got on it a couple times after the car got up to temp. Once I got off my exit on the interstate and came to a stop, smoke was coming out of my exhaust like crazy at idle. Once the light finally turned green I could see it still in my mirror but not as bad. Hit another light and it was smoking quite a bit... Any how made it back home and parked it.
05 Neon SRT-4 with only 20k miles. AGP 50 trim .63 AR journal bearing turbo. Has around 10k miles on it or so. I run 5w-40 full synthetic. Prior ran 0w-40.

It smoked like this last year. I put a new PCV valve in and switched out checkvalves and that seemed to fix it. I also did a compression check. All were almost dead even. Low at 125 psi but it could be due to doing in the dead cold on a cold motor and I have a small battery. But it makes you wonder. Removed exhaust side of turbo and it was dry. Not caked in oil or anything. I could still smell oil burning every once in a while. Then that smell went away. I also put a new AGP oil drain tube at that time since the one that was on it was seeping and sweating like crazy.
Now fast forward to now, a full year later she be smokin' again..... So trying easy stuff first. Put a new PCV LINE on since my factory one had flat spot in it. (hard plastic line) Bypassed check valve and catch can so ran a 3/8'' line straight to intake manifold from PCV. PCV valve still looks intact and fine. Can still hear ball in there when you shake it..Idles fine. No CEL. Pulled all 4 plugs, all looked good. Oil looked clean no coolant smell. Check coolant. Still nice and clean. Started it up, once it got to operating temp it started to smoke again. :( No smoke in engine bay.

Seems like it has a lot of play. But not sure if that is normal on journal bearing turbos. No in and out play which is good. I contacted AGP and they said that seems a bit more then normal and asked if the blade was hitting the housing, it is not. But could be..very very close! I checked the turbo drain tube out again and took the part off on the turbo side and it didn't seem clogged or anything.
Whats next on the list?
Remove exhaust side of turbo again? Will that show if the bearings/seals are bad?
Valve seals, headgasket, Bad exhaust valve?
Thanks guys for any help. I want my car to be running great again and not smoking. Here are a couple picture of the car:
