Possibilities are cam cover seal, plug orings, AOS.
My bet is on AOS due to location.

 

Does it drip all the time or just after you take the car out? I had an issue with leaking oil but it only leaked when the car was above 3000rpm. It turned out to be the spark plug tubes. It was pretty easy to change them all and was about $200 in parts and tools. There is a good write up on Renntech.org about it.

 

mine look similar to that..took it to RUF & they replaced the sparkplug tube/seal & Orings

 

breather bellows (AOS) or valve cover sealant/ cam plug. Reseal the cover, replace the cam plugs and the bellows. Change oil too.
Depending on engine the spark plug tubes some times leak...

AOS is my bet, had a similar leak and that's what it was.

 

The Oil seperator is a good one, also there is a breather line that is prone to leaking.

illistration 104-10, give you an idea of what it is.

 

Also a common area for oil when the seal on the cam advance solenoid on 3.4 engines leaks.
