Good question Curt, we'll have to get a rental to test that theory out! (kidding) I've had a few engines with the low oil s/d system, but never had a functional test thank goodness. Not sure if it's level or press activated. That plastic drain valve is a scarry pc of equipment. The brass part threaded into the block is fine, it's just there is nothing you can do with it. It's just a wide open nipple without the plastic twist cap in place.
