I use a catch tank that accumulates about 2+ oz of blowby in 25 hours
and I routed the vent within 1/4" of the top of one exhaust pipe. Maybe
there is a better way to assure "burn off" of the mist from the vent,
but my exhaust pipe has a stain that indicates some stuff is hitting it.
I still have more oily residue on the belly in 50 hours or so than I can
put up with.  

The engine is a Lyc O-360 that has used 1 qt every 15-20 hours since
new.  I have a AC Spruce (aprox. 4"x3" cylinder Separator) that may not
be the most efficient design.  Maybe the new Andair Separator I plan for
my Legacy will do a better job.  In any case I believe you can reduce,
but not eliminate belly stain.
