I had this noise appear on my '96 two summers ago. Scared the **** out of me at first. It literally sounded like marbles getting tossed around INSIDE the engine block. I located the source after a bunch of prodding around with a mechanics stethescope. Sure enough it was the a/c compressor, which was a HUGE relief to me considering that I thought the noise was coming from the engine itself.
Anyway, I removed the a/c belt from the pulley for the winter and when I reinstalled it the following spring to get my a/c back in operation, the sound was mostly gone. Can't explain why but I'm still running the same everything. Given that mine was making some pretty major noise and now its fine leads me to believe that its likely not a critical issue.
