Mine leaks from that vicinity too. I'm pretty sure it's leaking from #3, the large timing plate gasket. I've replaced all the easier stuff like the oil sender washer & dipstick o-rings, but the leak is still there. It seems to ooze out the driver's side and then down onto the oil pan flange, finally dripping off the drain plug.
I'm just putting it off until I decide to do the whole timing chain case rebuild. It'll need that sooner or later.
