Yes I cleaned the housing good. Flushed the passages with the vat at work. I caped off the pcv with a rubbercap and it still screaches. Which makes no sense. I used a new felpro gasket from advance auto parts. The bypass valve is open at idle and and closes when u snap throttle. All vac lines and evap lines are hooked up. I'm a Nissan master technician for a living. Only thing I can figure is there is blocked port for the pcv system. The supercharger gasket has 1 hole where the supercharger has two holes at pcv. Why is this?
