To use the 4 gaskets on the valley pan or not?

Well, looks like another issue has arisen. Took it down the highway a little bit and around town to make sure there weren't anymore issues, and started getting a little smoke. Popped the hood and I got oil everywhere but I can't tell where it came from. Obviously my first thought was that pan gasket, but I don't see any oil around it at all. This didn't happen until about an hour after driving it so it could be unrelated and I'm just unlucky.
