I have seen some of the members here adding ways to drain the oil tank. 911s have a tank drain, but their tanks are mounted fairly low in relation to the engine. The bottom of the 6 tank is close to being near the same height as the top of the engine caes. Won't the oil just run into the engine case?

I am very happy I did this. It drains very quicky and isn't messy like disconnecting fittings. I use an aluminum washer from the valve cover as a sealing ring.

That’s nice
-12 or -16? Scratch that ….. pipe thread what size?
Where did you find it?

I’ve been splitting aluminum AN fittings in my line since 2005 without issues
Probably over 150 oil changes/events

That is a Porsche factory fitting... AKA a Cohline fitting. Drilling it for a drain plug is the modification.
