That "clacking" sound could possibly be your valves. Maybe there isn't enough oil getting there, or 1 or more of your valves are stuck open. Check your oil level and add if needed.

Here are some suggestions: if you can afford it, replace the valves, if not, turn your music up louder until you can afford new valves.

Uh, or simply do a valve adjustment?

Valves will make a consistent "clicking" noise during normal engine operation. Usually it's more noticable during idle. Is this sound erratic? Does it clank once, then stop for awhile? Or is it a consistent noise?
