Let me take a wild a.. guess here. My thought is the vent tube to bank 2 possibly got cracked or broken when you changed the AOS (20 year old plastic does this if disturbed). This could cause the lack of sufficient vacuum in the crankcase causing the AOS to continue applying vacuum from the intake ( max intake vacuum at idle) and pulled oil into the system. Since you now have/had liquid in the intake be sure to pull the spark plugs and turn over before attempting to start again.
Oh and I second NOT using a metal impeller lathe.
