Light tapping/knocking coming from front of engine

I have a very light, not very loud but definately noticable tapping/knocking sound coming from front area of engine bay.

any ideas? or anyone else have similar issue? and is there a DIY on replacing the belt?

does it increase with road speed or engine speed? sounds like little marbles? could be bad octane gas or the tensioner

it does not increase with rpm's, that I can hear. yes, kinda sounds like marbles I guess you can say. or someone taping a wrench

you can watch it when the engine is running. If it looks like its vibrating then changing it would fix the problem. Repling the belt as well too

a 14mm wrentch. 12mm socket and ratchet. 14mm serpentine belt remover tool comes in handy. the 14mm bolts you can see. the 12mm bolt is hidden below. feel around for it...its there
