It has a hose going from the oil fill spout to the upper intake manifold,

This one? That's the PCV system fresh air line. It gets air from after the air filter, but before the manifold (just before the throttle plate is a handy place) and feeds it into the fill tube, through the crankcase, and out the back center where the PCV valve lives. You can't see the valve unless you crawl onto your engine, but you can feel it if you break your elbow so it bends the other way.
