Here’s some pics of my new Stahlbus drain valve. There’s no way for oil to leak from this unintentionally. Not only is the main valve a ball-check, there is a 2nd cap that’s sealed with o-ring. There is a small, 1/4 turn insert that’s attached to a chunk of hose to aid clean drains.
I’m actually thinking about attaching my vacuum extractor to the hose so I make sure I get a complete drain by being able to put the whole engine under vacuum
