You should never return the oil from an oil separator to the crankcase 
!  Its the most vile, disgusting collection of gunk Ive seen come out of 
an engine...

If you don't believe me, capture some in a small one pint bottle ( like 
I did in the inclosed pic...upper left corner) and take a whiff of that 
stuff... awful !

You can vent the line that comes from the "collection side" of the oil 
separator to the outside of the cowl, but that will leave a nice looking 
oil streak on the cowl.

Better to capture it like I did, that way you can see how much oil is 
being separated out.  Mine is about two feet down from the separator 
using a rubber hose stuck in a Revlon polypropylene bottle.  Simple got 
the bottle from my wife.  I usually empty the bottle every 4 to 6 months.
