Guys, its been a long time! Of course most of you may not know me since I was a 951 owner for years. Well, I guess I skipped a few models and got the ultimate car (to me anways

).
The car has 31,000 miles and serviced well. The previous owner spent a ton of money on upgrades. It has the GT2 (OEM) front fascia and carbon fiber wing as well as an EVO air intake.
The leak is makes a few drips at a time and seems to come just above the rear sway bar. Oil consumption is negligible. My question is this someting to really be concerned with? Any ideas of what seal may be leaking?
I will try to get pics for you soon.
Its good to be on the forum again! Thanks for your help as always!
