I suggest you read flat6innovations write up ( google intermix 986 boxster) and click into article. compare your symptoms including what happened up until seeing the intermix issue.
I doubt it is the AOS or the oil cooler, or a blown head gasket. Boosters don't blow head gaskets very often.
I don't know the mileage but hope it isn't the dreaded cracked head. Oil reads high and coolant disappears. Does the temp light flas slowly now?
Let us know.
