That same plate on top of the passenger side valve cover is leaking too, is it just an o-ring there?

I just bought a 96 Outback 2.5 and on top of the valve covers on the driver side where the oil filter neck bolts up that plate is leaking oil bad. Is there a gasket or o-ring under there and what's it called? I've googled and can't find anything.
