Sounds like crud in the intake from the PCV. The crud blowing up from your crankcase into the driver's side of the intake (just after the throttle body) is worst when you start the car and turn it off shortly thereafter. Many of our cars will then blow blue smoke out the tailpipes momentarily upon restarting the car. Forced induction aggrevates this. I fixed this on my car by installing an oil catch can (with PCV valve inline) between the driver's side valve cover and the intake manifold.

Time for an oil seperator (catch can), then.

Then it likely will. Click here for a lengthy discussion here about oil catch cans.
