help!, more noise from engine, not injectors

[90dpscoupe]

This time it sounds (clicking) like its coming from the pass side of motor, in the front somewhere, i put a big screwdriver on the alternator and can hear some noise, but sounds fairly normal?, i put it to the belt tensioner and can hear all kinds of racket, could it possibly be a locked up smog pump?, has anyone experienced this? i didnt hear anything under the valve covers out of the ordinary, and have normal oil pressure.

any help would be appreciated, as i am pretty stressed out over this....thnx
