Oil leaking through headgasket?

Oil leaking through headgasket?
Hey guys, I'm looking at purchasing a 2005 C6 with 82,000mi on it. Its a pretty clean car, and cheapish at $17,000. However, I did spot some oil residue on the passenger side cylinder bank where the head meets the block. Alarm bells rang to my untrained eye.
I consulted a former coworker who is a certified world-class GM Master Technician. In his many years of experience, he has never seen oil leak through the headgasket. He's convinced it shouldn't be an issues and just needs a clean.
I took the car for a vigorous test drive and watched underneath the car for a good minute or two for any drips and found nothing. The oil was clean and the coolant is clear. Car pulled strong and had no performance issues. Temps held around 210 for the length of my test drive and about 15 minutes of idling after for a total of about 35 minutes.
Take a look at the pictures and let me know what you guys think. Could this be a leak from somewhere else like the intake or valve covers? The dark spot seems to originate from the valley area.

Don't be looking at a 12 year old car & expecting perfection, any car that age will have some imperfections if you look hard enough. I don't think there is an issue with your concerns

The world class GM tech says its okay...but you ask opinions here from people you don't know but trust?
You say it's not the techs 17K but you still asked for his opinion. With that kind of attitude you shouldn't have asked him in the 1st place.
Not trying to be a smart *** but it sounds like you are looking for a reason to NOT buy the car.
Bottom line...man up and buy the car or not, but don't waste time asking for expert advise that sounds like you've no real interest in taking. If you have a bad vibe...well, you know yourself better than we do.
Again...I am not trying to be a smart ***. You asked what we thought.
Good Luck!

It's as simple as this;

From what we can see it looks like the filler neck was the cause. Easy enough to spill a little oil there.

- Yes! The world class GM tech says its OK. But more information from folks who have experienced something similar to further corroborate what he said would be great too. Why else does the forum exist if not to share experiences about the common interest we all share?
- Yes, because the final decision and funds come from me and my bank account, so while his information is valuable, I don't think its fair to say I'm wasting anyone's time by seeking more information from owners who have seen similar on their own cars.
- And yeah that's exactly what I'm looking for, a reason to not buy the car. Do you not look for problems or negatives when you make your decisions?
It never ceases to amaze me that somehow, anytime I see a new member join a forum and some salty old dog comes out to pick his post apart instead of simply providing feedback as the other 6 or 7 people managed to do in this post.
Just because you're "not trying to be a smart ***" doesn't mean you aren't one. Thanks for the warm welcome, and I hope you have a better day!

Yes we do but again, your brilliant GM tech says its not an issue. There is no reason to not buy the car if that was the only issue you found.
It never ceases to amaze me that somehow, anytime I see a new member join a forum and some salty old dog comes out to pick his post apart instead of simply providing feedback as the other 6 or 7 people managed to do in this post.You asked for opinion on what might be the issue.

@ BlindSpot...I hope not.
OP took my comments the wrong way. I explained myself and hopefully he now understands there was no malicious intent. Either way, I'm good to go.
