Oil in air filter

[anonymous-user]

While fixing my imbalance problem (see other thread) we (me and my more mechanically attuned mate) spotted a fair amount of oil in the air filter. I'm going to give HHC a ring but just wondered if this is normal?

The oil filters (if the same as the Cerbera) are heavily oiled, check the airbox just to make sure though.
