if it is running, im guessing lifter noise. if you change the oil and put thicker oil in it, and it solves the problem, then im right.
A nick, crack or tear in a belt will make a tick soung as well as a water pump that is going bad.
Tapping valves is a noise made by too much clearance between the valve lifter and the valve. Modern engines have hydraulic lifters. If you have too little oil pressure or run the engine low on oil, the lifters will make noise. The lifter can also wear out.
Rocker arms dont break. Pushrods bend and lifters malfunction, but rocker arms rarely if ever go bad. A bad lifter will make an obnoxious taptaptap noise. A bent lifter will cause significant backfiring through the carb or fuel induction system.
If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do

One might find the directions on how to make a cup lifter on sites such as eHow. Another way one might find out how to make a cup lifter would be to look in books at ones local library.
