Using Mopar Performance cast aluminum valve covers on 511 build with Sniper. I have the correct PCV grommet for this valve cover but I can't locate a fixed orifice PCV valve that works with the grommet designed for this cover. The ID of the grommet is .470. I can't find any fixed orifice PCV valve for this application. Does anyone know where I can get the correct size valve for this application. Even an old style PCV valve would be OK. I know they can be modified into a fixed orifice type. Thanks
