very noisy sounds like a marble rolling around in metal and the sound disapates as you increase rpm and returns when decreased seem to come from top and side of motor where pulleys are

any ideas> ? thanks

now noisy high volume or just noticeable. I can only think a broken spring, bad pcv valve, lost valve retainer, you should probably take off the valve cover from the side it sounds like it'* coming from, or probably your charger

thank not sure think it was a bad description I went out and listenagain sounds like clacking and it goes away when rpm is increased seem to come from the pulley are completely and upon further inspection i think it is the tensiuoner pulley are?
I wondered if i filmed it i could upload the video here?
