So, fiishing up my 408 build and i need some help with the pcv routing. Do i need a catch can? I have the pcv valve in the rear of the drivers valve cover, two emply ports on the passenger valve cover, a port on the intake manifold under the throttle body and no idea what goes where. I bought a filter that has a one way check valve in it that will go on the oil filler. Right now, i have no hoses on any ports. Help.

PCV valve to intake manifold port. Catch can in the line running from PCV valve to intake manifold. Check valve filter installed in oil filler. Check valve should be open under vacuum to allow clean air to enter passenger side valve cover. Cap 2 other passenger side ports.
