This just started happening about a week ago. If the car sits at idle for more than 5 minutes it starts smoking. The smoke looks like oil, but it smells more like fuel. Once you rev the car up it cleans out and won't smoke for another 5 minutes. The car does not seem to be burning oil either. While driving it does not smoke at all no matter how hard it is driven. Only after revving up from idle. The car has a Turboxs stealth back exhaust with high flow cat. I have never had boost creep or hit fuel cut. The car still runs strong and does not run any different than when I bought it. The only two possible causes of this problem that I can think of is a bad motor or leaking turbo. I hope I can figure this out; any info someone could give me would be very helpful.

Thanks,
Joe
