Are any of you experiencing or have previously encountered noise (like crickets chirping) coming from your engine bay?..more specifically from the belts..(fan belts, pulleys, etc..) I think mine comes from the a/c pulley belt, as the noise started after i changed from stock to lightweight pulley.. i've tried using wd40, rubber grease, fan belt spray, even tooth paste... but the noise ALWAYS comes back after a day or two.. (btw, the tooth paste works the best..) is there any other way to remedy this? Or is it due to inferior quality belts? I'm sure everybody would want their exhaust to be heard rather chirping....help! thanks..
