Reported cause
And then a year later had a leak in that area and it was the AOS, haha.
Leading evidence: 'aos, haha' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'aos, haha' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace air oil separator' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suspected cause
Correct, my comment was not meant to imply that you should only suspect your AOS, I was only intending to shed light on the fact that factory fresh ones have and can fail.

Leaked from the rms but it turned out to be a poorly installed IMS flange it cost me a lot to get fixed I hope yours is easier and cheaper good luck.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

OK, was smelling a hint of oil after a good drive for the last few weeks. Didn't really see anything obvious, so I thought it was normal with the increasing temps outside.
Fast forward to yesterday. Car had been parked for about a week. Went to take her for a drive, pulled out of the garage and noticed some "liquid" on the floor. I checked it out and it looked like several drips of oil. I wiped it up and put the car back in the garage. She was parked for about 20 hours and it looks like one drop of oil on the floor this morning. Not a huge leak, but I can't stand ANY leaks. I jacked her up to have a look. The drip is coming from this area here, drivers side. If I am not mistaken, this is the oil pump/cooler?????
In the pic above, there is what looks like an access cover, maybe a spring retention cover, on the backside (forward facing side) of this.
I have not yet purchased a Bentley Manual, so any quick help would be appreciated. Thank you.
... Leaked from the rms but it turned out to be a poorly installed IMS flange it cost me a lot to get fixed I hope yours is easier and cheaper good luck.
Complete engine out service, to include AOS, RMS, plug boots, etc, etc were all done within the last 5000 miles. The area above the object in the picture is dry. No oil leaking or weeping from above.
Unfortunately for all of us who have not yet upgraded to Skips UAOS the failure rate and expected life of a factory/OEM AOS is a funny little bingo card.
It absolutely would not be the first time one has failed that fast. There are plenty of stories of people going through 3 in one year and of brand new Porsche branded ones (not even cheap aftermarket) being bad right out of the box. They really are quite poorly made/designed and we are very lucky to have Skip's fix to save us all a lot of hassle and headaches.
AOS is passenger side; so that seems an unlikely culprit.
No matter how many times I�ve been under my car; these pictures still turn me around.
this is the drivers side of engine towards the front of the car correct? If so, oil cooler is on that par of the car, cam plugs are also a possibility I think. Hmmm.
Correct, my comment was not meant to imply that you should only suspect your AOS, I was only intending to shed light on the fact that factory fresh ones have and can fail. I would not rule it out simply because it is new.
True. Since the OP's profile says US I assumed..
I always struggle with pictures submitted on these forumns to get the correct angle of how the picture was taken. There also isn't any kind of note/circle/notation on the picture of the area in question. The one area that looks wet to me seems to be a picture of one of the timing chain tensioners. If I recall correctly and since this is a picture from the bottom of the car, that would make it bank 1 . The AOS is on the bank 1 side. Could be someone didn't use a washer/gasket on that chain tensioner or it's just not properly torqued and it's leaking. But like i said, I have a hard time with spatial orientation on pictures like this.
Let me admit that I was indeed turned around but also having straightened out my bearings say that I had a leak in that area and it was from the cam solenoid seal. And then a year later had a leak in that area and it was the AOS, haha.
and I think you were referencing that cam solenoid seal in your pictures.
here is a thread about it:

I will post a better pic sometime today. The pics currently posted are taken from the rear, basically looking forward. Leak is on the drivers side, as noted in the original post. Comparing photo's, I think Neil's diagnosis may be spot on, as it looks in his pictures that my leak is coming from the same area. More to follow and thanks for the help !!!
They can leak but they don't leak up like that. The second picture shows at the very top of the picture the actuator solenoid with its very fuzzy flange. That can leak. There is no picture showing the front face of the head where several other things can leak such as RPM counter, AOS numerous ports, scavenge pump (less likely).
This is a source reference. Confirm exact model applicability in the original material.
