[DML] Funny "whizzing" sound from engine

["sweetp01569" <paul.sweet@xxxxxxxxxxxx>]

I am not sure how to describe this sound I hear from my engine, but 
its like a whirring, whizzing sound I get during various times when 
accellerating.  It does not affect the engine performance when I gas 
it.  It seems to come from the engine compartment.  It sort of sounds 
like an air wrench on tires being changed, that 
fast "fschweez", "fschweez" sound (how that for wording a sound!).  It 
comes and goes, varies in intensity (shorter and longer bursts).  I'm 
not sure if it's a vacuum leak, or an idler bearing, etc.  Perhaps 
someone can shed some light for me.  I have a couple other questions 
that I will post as separate subjects.  Thanks for any advice. - Paul
