My BOV goes


I noticed this morning the perrin check valve started whistling at idle, like a tiny supercharger. At first I thought the turbo was about to have issues then was relieved to find out it was just the check valve. I've read on iwsti that perrin was working on a solution and that they were also sending out a barbed fitting that allows you to screw the oem pcv into it and use it inline instead of the plastic check valve. I may go that route or just buy a better check valve.
