What problem or system could cause a clicking noise coming from the engine of a 1987 Mazda 626 when it's on but the car seems to be running fine?

There are a few things that can cause a clicking.. first is valve tapping which is when the valves become a little loose and the noise you hear is when the gap is taken up and the metal taps, second is that the bearings in your water pump may be starting to fail, and third might just be that your belt has a bad spot and clicks as it passes a certain pulley.
