Looks like it's weeping a bit. That looks like it's just an oil galley plug, and doesn't hold anything in (I'm sure someone with a manual can confirm that). At you're next oil change, maybe just pop it out and try putting some aviation sealer or thread sealer on the threads and just reinstalling. I wouldn't be too worried about it though, as it's not much of a serious leak.
