The ADBV is always on the inlet end, its rubber (or similar material) that covers the outer inlet holes. It allows oil to enter filter but the oil pushing back against it seals the inlets holes and stops most from escaping.
This is what you are referring to? Not the Bypass Valve?
btw-GM engines incorporate a bypass valve into the filter base, so its not needed in a filter but will not harm anything if it does have one.
