[200q20v] Is it my turbo?

[WARATAP at aol.com]

Lately (for the last month or so) under light acceleration as the car vacuum 
boost gauge makes the transition from vacuum to boost, I can often hear a 
sound similar to what one makes when blowing over the top of a soda or 
(better yet) beer bottle.   I haven't checked the positive pressure hose yet, 
but my IC does have a copious amount of oil at the bottom of the endcaps.

Anyone else experience this?  I'm still getting 20+ lbs of boost, but maybe 
the bearing is going?

I'll be replacing the turbo afterrun pump next week (leaking).
