Its too bad the camera doesn't really catch the BOV as much as just engine noise....
The pressurized side of the intake does not suck in air through the diverter valve. It only feeds excess pressure to the pre-compression side. The valve is triggered by a vacuum line from the manifold/TB. I have checked it and it never sucks air in.Any suction would be coming from the pre compression intake ducts. That is why when you disconnect the diverter valve hose, you must cap those plugs. Its all explained on page 1.
