I know the screwdriver trick, I used it to diagnose the ticking noise I got when I first got the car (man our fuel injectors are loud!).
But that's the real problem. It doesn't happen except under load. If I park the car and put her in neutral and rev up, I can't hear the whine. The Legacy was the same way...
I've gotta find a way to rig up something to record parts of the engine bay while driving. I hope it's just a vacuum line or something making noise...
