Smoking problem

[Saltman]

Help! My car has been out of the shop for about 1 1/2 months after the swap. Since then, after I broke in the clutch I noticed that when I ran the car hard (shifting above 4000rpm) it would sometimes start smoking at idle, say at a traffic light or when the timer is counting down. It's a white smoke that steadily comes out the exhaust for a minute, and sometimes it would dissappear if I stopped again and re-appear at the next light. I'm afraid to get pulled over for this. It smells of strong exhaust fumes. People have told me my car could either be running rich or it could be the turbo seals and gaskets leaking. Has anyone else had this problem or know how to fix it? Help me please!

Mmmm..white smoke, sounds like oil.

No I haven't overheated it yet. No matter how hard it's run, the engine still stays fine, needle in the middle of H-C. I did change the oil to Synthetic Mobil 1 10w 30 though. Autobacs did the change. Could it be leaking through the turbo? I keep checking it and it doesn't appear to be draining. Still at the same level as it was 2 weeks ago. Have driven about 1500 miles with it.
