The oil vapors get in there due to suction from the intake and will condense back to liquid. Hot oil flows better through the slightest openings easier than cold oil. Also check the metal for any imperfections. A slight indentation, and hard rubber ensures a potential leak.
You could also clean the area's really well and use a bit of RTV, but then that will have to be redone every time you take the valve cover off.

OK, I'm going to get new elbows then... If that really solves the problem, I'm going to kick myself in the ass for not having done it earlier... with the car leaking oil on the garage floor for two years... I really hope you are right about that... it would be a very easy, low-cost solution... (wondering why no one else here suggested it before)
Thank you very much,
Rino
