WAIT!!! Ok this is gonna sound silly, but I left mine threaded in like one thread cos I'm in a tiny garage and it woulda taken me a while to get back around to turn the car off after taking a look (I was home alone and didn't wanna make a big mess).
Just took it the whole way out and started it while the mrs looked and she leaked oil :) the one or two threads I had it turned in must've sealed it a little.
So I can confirm it pushes oil out on the 12R... Sorry if I messed you guys around at all haha.
