HKS SSBOV Question

[BoostInsideTSi]

Hi everyone, I've got a HKS SSBOV in my car, supporting my 16g turbo set up. I've noticed the sounds coming from the BOV have been different lately than before, so I looked at it, and noticed the adjusting screw (goes in the side of bov) is missing, and there is a hole where it used to be. Any idea if this effects performance, creates a boost / vacuum leak, etc? I need this car to be running the best it can! Thanks,
Mike

You're going to be leaking without the screw, so you'd better get a new one.
