'windage' ..
in AAZ 1.9 TD engines and tdi's ..they all use a 'windage tray' ..
helps keep oil away from the crankshaft .

waterboxer is a little different ..
a more shallow sump.
     In all the  VW air-cooled engine building and hopping up over the last
several decades that has occurred, maybe someone has made one for air-cooled
VW opposed fours, which are similar in the sump area to waterboxers.
