On an N/A engine & looking at your pictures,,,I would remove the red hoses between the 2pcv valves & front of intake.
Connect the 2 shorter black hoses to the intake & remove those nipples from longer outside black hoses & connect to pcv valves.
The tank is most likely baffled & has at least 1 oil drain.
Unless you see some arrows or other indication of flow...that is most logical way.
