Varioram Resonance Flap Assembly Oil Leak

I have been watching an oil-damp area on the bottom of the left cam chain cover gasket the last several years.  This condition has not resulted in any oil on the garage floor until now.  I've believe I've traced the source of the oil to the top side of the engine, specifically the Varioram Ram intake manifold Resonance Flap Assembly located on the bottom center of the manifold.  Is this an issue you have seen?  What would be my next steps to diagnose?  The car never smokes on start-up and does not consume more than a 1/2 quart of oil every 3,700 miles.  The car is typically driven for fun runs and Drivers Ed events.  I have owned the car for 10 years.  Your expertise will be appreciated.
