OK, I was taking your comment "small puddle accumulating in the front of the pass. side inj. hsg." literally in front of the injector housing, whareas it is on the side of the injector housing, towards the front.
Oil leaks at the location shown in the photos is typical & often associated with loose injector housing bolts.

1. thoroughly clean & degrease gasket surface,
2. clean & degrease all inj hsng bolts,
3. install new gaskets, no sealant required on Jerrys Gaskets, others may benefit.
4. apply loctite 242, med strength (blue)
5. tighten/torque bolts as per serv manual pattern

Installing an oil catch can in the PCV return loop will do nothing to fix the leak you are concerned with. The catch can will only collect some of the oil that would otherwise go back to the plenum.
