Default Valley Cover leak or not?

So I had previous replaced both valve cover gaskets due to obvious leaks and a small leak continued. Not enough to leave drips in the drive way while parked. So I figure it is only leaking while driving? I reached behind the intake after driving and found some fresh oil. So today I pulled the intake and removed the oil pressure unit.

I took a few pictures and I am now wondering if its the rear side of the valley cover gasket? Can anybody tell if it is or not from the pictures?

It's possible, but I think it's more likely to be the OPSU, or CPS.
So otherwise does the engine run good?

Well oil pressure is kinda wacky. At times it'll zero out and it looses power, the check gauge light comes on. Other than that it runs like a champ.

Normally my gauge sits at the quarter mark of the gauge which concerns me since my previous WS6 always sat at the half mark(was an A4)

I want to say it's the OSPU, but I would still check to see if it's thrown any codes, that will tell you a lot.

Well I went ahead and just swapped the opus. I have not noticed any leaks so far though the oil pressure issue is still there.

I'd still get it Scanned for codes, but figure on replacing the oil pump O-ring and/or pump.
