I'm actually chasing a "leak" in that location as well.  It's more of a "weep", really, as I can't see anything dripping, but everything gets oily there, and it's finding its way down the side of my motor, across the coil-packs, etc.   
On mine, I'm of the opinion it's the Crankcase vent hose.  This is the "accordion" hose that connects the left-side camshaft housing to the AOS on the right side.  It snakes around across the top of the right-side camshaft housing.  Mine is wet with oil all along that length.  It didn't smoke when I smoked the engine, but it'd have to get through the AOS or a check-valve to do so.  
the Oil Fill tube is further towards the center of the motor, as opposed to the crankcase vent line.  I don't think it's my culprit.
