YESTERDAY, I WAS AT A DRIVE THRU, AND HEARD THIS CLICKING NOISE WHEN I TURNED MY RADIO DOWN. I THOUGHT IT WAS ANOTHER CAR, BUT LOW AND BEHOLD, I WAS CLICKING.
IT WOULD GET WORSE OR ACCELERATED WHEN I WOULD INCREASE THE RPMS. ANY IDEAS?

 

First off, take off the caps lock. You don't need to yell.

It could be loose rocker arms, an exhaust leak or something else. You need to try to isolate the sound as best you can.
