Weird noise...
 

When I got off the express way this morning I heard a weird sound, kinda like a dull drill bit.

It went away, and after work before getting back onto the express way I heard it again and it get louder as I go faster, and I heard it even when I was stopped... But it doesnt do it all the time....

Anyone have an idea what it may be?

Thanks

Heatshield Rattle Maybe??? :S

worst post every. I have a noise on my car sounds like a duck...what is it?
is this supposed to be a damn riddle? give more information, man..where did u hear it from..etc

Well it's from under the hood somewhere... thats all I know, I think it's a belt... because it makes the sound even when I'm stopped...

But did it only make the sound once and a while?

Like mine just started today, but it's not constant... it's weird...

What sounds do the different belts make?
