my car has a hard clicking noise like metal to metal.. when the revs are at between 2,000 and 3,000. then stop and start againg after 4,000,,, if I release and punch the trothel I can hear it clearly... I had the valves checks and timing belt and they are ok... what it could be.?

ohh.. is a civic 93 with mini-me

 

spark knock?

 

might be detonation.. mini-me's run under high-compression usually..

 

The hamster is trying to escape.

Check timing and make sure your not detonating.

 

i have that to but its just my exhaust rattling

 

This is just a thought...try advancing your timing from stock 14' to 16' and see if that stops the detonation. My engine has high compression and ran smoother when advanced. Just a thought though.
