Is it normal to grease those joints or is it a sign that it's failing ? In fact both sides are greasy, just the driver's side is much more greasy.
Also on the rear passenger side (rear driver side for US cars), there is a pipe with a vent that seems to be venting out oil - not much but enough to coat the surrounding area with oil but not enough to drip to the ground. What is that vent ? It's to the right (if u are facing the engine) of the a/c compressor.
I had taken pictures but still trying to figure out how to insert them into the post here ! (ah success !)

the control arm mount is nothing to worrry about it just grease seeping out, they all do it, the vent , hard to tell from that pic where you are but it appears to be your air cleaner drain which cannot spill oil unless you have a K&N air filter and overoiled it in which case your MAF sensor would not be working correctly. Porsche Boxster does not vent any oil, that I know of, to the atmosphere, even the crancase breather is recirulated and ingested by the intake manifold.
