It takes a long time to ruin the cat with burning oil, less time to coat the rear O2 sensor. The oil should only be present during throttle lift off.

Reaching the oil separator requires intake manifold removal. But, in your case, a thorough cleaning of the PCV (next to the throttle body) would help. Note the small vacuum line there and make sure it is not filled with crud. There should not be a screen (flame trap) in with the PCV valve. If there is, throw it away.
