Before I was mainly thinking rear main, but now I guess it could be that or the oil separator plate, or this access cover o-ring that this guy mentions in the video. If you see on that particular motor he's servicing there is a leak coming from the access cover, and he mentions that the o-ring for it likely failed.
I've been trying to find out if there's a specific Subaru part # for that o-ring, or atleast some aftermarket replacements, but no luck so far.
I won't know for sure if that's where my leak is coming from until I pull the motor sometime soon when time allows, but if that is my problem, or part of it, I'd like to be ready to fix it then.
