Whining noise...

[William Glenn]

Hey all,
I've got a seriously loud whining noise coming from what seems to be around
the timing chain, directly under the valve cover under that side of the
motor.. It increases in pitch with the rev of the motor...  What could be
causing it, it's not the belts i'm sure. I took the valve cover off and I
can't 'see' anything wrong with it.. I just turned 30k miles, and this noise
is really freaking me out... I appreciate any help!

Thanks,
William Glenn
