Oil leak

[Noslofivoh]

Found a leaking oil cooler, imagine that, so I am changing out the cooler and figured I would go ahead and swap plugs while there. After I tore apart the upper plenum, while removing the accessories, I found an oil leak that has me baffled. It is from the back of the drivers side valve cover we gasket. Attached are pics. Could that possibly be from the oil cooler? Or where? Valve cover gasket, maybe?

simple green, let it soak, wash it off, try running it to see any leak, if not, put some die in oil, run engine.

Looks like a cam sensor.
I had the same issue with both my 3.6 seeping oil.
I remove each one and used RTV silicon on the rubber gasket to seal it up.
