 I purchased and installed an oil/air separator from
 Lancair.  It was made by Andair but was missing the
 internal parts.  As you might guess it did not work
 very well without the internal parts.  However, thanks
 to Robert at Lancair and his correspondence with
 Andair I did receive the parts.
 
 When the separator was hooked up without the internal
 parts the return line went back into the case just
 above the oil filter on the back of the engine.
 Hooked up at this location I had oil venting all over
 the belly of the plane.  I do not know if it is the
 location that causes a problem or just the fact that
 the internal parts were missing from the separator.
 Consider that hooked up as it would be without an
 oil/air separator there is no oil venting overboard.
 
 My plane is currently down for an annual so I have not
 flown it with the system hooked up with all parts in
 place.
