BOV whine??

Installed a HKS bov in my legacy b4 and on acceleration it makes a whine noise almost like a straight cut gear box, but blows off fine, is this a leak or does the screw need to be tightened?

Tighten it and see what happens. If I was you I'd put the standard one on

Thanks gonna try replace the gasket and tighten her up and if not its coming off!
