Boost Problems, Please Help Options

[CheesyLobster]

So ever since I put on my turbo charger I've been noticing a few strange things.

1. Before anything, I noticed a somewhat strange smell coming from my car. I believe that it's coming from the exhaust.

2. Sometimes (but not all the time, which is strange) I'll boost to like 5 psi and i get a ton of smoking coming out of my exhaust for about 3 seconds after the boosting, then it stops.

Some things to consider-
My oil return line could be straiter down than it is... I'd say it’s at about 20 degrees off from strait down... Also, the return line is about 1/2 inch, which I hear is small for a return line.
The smell from the car could very well be oil, but it's hard to tell.
Also, I've never had my car dyno tuned (yet, I'm waiting until I get on my BTM).

Otherwise, the car seems to run fine. Could this be something more serious like a piston ring? Or do I just need to tune it, or straiten out my oil line? Where should I go with this? Ideas??

Please help, thanks.
