The screw and fastner on mine are gone and I dont know what to do. Everything seems to be working fine, the car doesnt seem to be affected and I can still hear it blow off. Do I need to replace it or what?
Thanks

The adjustment determines how hard or soft the spring presses down on the diaphragm inside the BOV. With no adjustment it's at the softest setting. It'll blow off no matter how soft it is. The problem is that it will open under boost and effectively be a massive boost leak. You need to replace it. I've never heard of anyone losing this so I'm not sure where you can finde a replacement. Maybe a screw from a hardware store will fit.
