open the pass side acess panel. start the car and rev it to 2000 rpm. reach inside the panel and feel the pump. it will be vibrating as the fluid goes thru. if you feel a loss of power feel the pump. if it insnt working its bad

when i first put the catch can on i didnt see much oil. after another oil change i drained the can and got at least 1 oz. out. thats oil that would have gone thru the t/b into the manis and clogged everything up. for the price it cant be beat
