Hrm... Looking at your picture, I don't see the adjstment screw in the top of the BOV. Did it fall out or something? The bottom port shouldn't be connected to the same place as the top port. It should attach to a pressure only (not vacuum) source, to blow the valve open. After you take care of the vacuum routing, find the adjustment screw and tighten it down until the valve stops leaking. Then, tighten the jam nut so the adjustment screw doesn't back out.

i always left that bottom nipple vented.
Yeah, I believe it is there only for those running really high boost, that have to crank the screw down really tight, to keep compressor surge at bay with less boost (part throttle and such). I don't think it will hurt to have it hooked up on a lower boost application...
