I do not know if the plugs get hot enough externally to burn off oil though. A warm engine has a much shorter plug duration remember. the glow Plug external heating then would be far less.

Interesting idea ... it actually does look like it's coming from that area. Also when my mechanic lubricated the throttle linkage he was extra thorough and got grease everywhere.  Any interesting theory. I'm not sure if the plugs would get hot enough externally, but watching the area while the cycle is on should give a clue I guess.
