Noise under hood??

[FlyGuyKy3 at aol.com]

I have a few noises which increase relative to RPM gain.  I was thinking it 
might be the belt because they are cracked, but then i noticed that the car is 
2000 miles overdue for an oil change.   (I just bought it a few days ago).   
Just wondering if there is any noises which are "normal" for an audi engine 
that have 100+ thousand miles on em.  Thanks for any help.
