I'm pretty sure, someone chime in if I'm wrong :??:StngStr said:Are you sure about this? So you're saying that it sucks fresh metered air from the intake tube (PVC valve hose connects to intake tube) then into the passenger side valve cover and then blows out the drivers side valve cover and into the blower? For some reason that sounds fishy to me. I thought that the passenger side valve cover pvc was for air to vent OUT into the intake tube and then be burned via combustion. Maybe I was wrong?
