The only thing above the exhaust Manifold is the cam cover but that does not appear to be leaking. I cleaned things up a little and I'm going to have to reinstall the manifold and see if there is still a leak. If it still leaks, I have to remove the manifold again and look for fresh oil.

If not the stud then the usual suspects are the Oil Pressure Sender and the Oil Level sensor if your MY has one. The leak can run along the side of the engine and gets to the bottom.
Best detection is a complete cleaning of all oil.
Then allow to dry and then a drive.
If it's still there it's then easier to detect.
Good luck.
