Default junkyard vacuum pump

So i want to hook up a vacuum pump to the back of my block to the black box for the pcv valve and one end to the valve cover with a catch can in between the pump.

So my question is what cars come with a vacuum pump stock that would work good for this idea i could just ****** one from the junkyard.. I think some old cadillac's had them but not sure if they would work.

I think any diesel vehicle should have one, because they don't have a throttle plate so they don't produce vacuum. The vacuum pump on one was used for the brake booster and other vacuum accessories.

only problem im finding now is that most of them especially diesel ones are mechanically operated.. I need a 12volt powered one.

yeah you'd have to fab something up to connect it to the pully syetem.

thats true.. ---- what are those things called bro? i was trying to find one on jegs but couldnt..
