Thought I read this either in Bruce Anderson's 911 Performance book or Paul Friere's excellent book; Porsche 911 Story. My understanding was Porsche was concerned about oil volume through the engine if a filter was added on the sump-to-tank side of the dry sump system. I guess some more research is in order tonight.
The oil is not filtered going to the engine as the factory wanted the engine to always have an oil supply.
