I stopped on the road with heavy (HEAVY) smoke coming from the left exhaust pipe (bank 2). I've pulled the plugs on and all three sparkplugs were wet with oil. When I pulled the front plug, about a half cup of oil ran out. Where could all this oil be coming from?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Failed AOS (Air, oil, separator). No more driving till you replace it with the UAOS, it's an upgraded AOS. Search here for the info...
I agree, failed AOS. The AOS vents to bank 2. When the AOS diaphragm fails, engine vacuum pulls in the oil.
replace it with UAOS sold by @Porschetech3
