ok I just got a turbo xs BOV used from someone on here...I know to hook the nipple on top to a vacuum source t on the intake mani......how do I go about mounting it on the intake piping....there are three allen screws on the bottom part of the BOV and when I took them out nothin change I dunno.....I was thinkin that bottom part was a flange ....should I jst jb weld it on?

 

you need a flange for it.... those 3 screws hold the bov to the flange....

 

oic how it works now......do you know where I could get that flange from?? thanx
