Jim, concerning your Air/Oil Separator, what do you need one for?  I believe
you said a while back that your engine used but a quart between changes,
after a very good break-in.  Obviously, some of that one quart goes out the
tail pipe and some goes out the breather.  Is it worth the bother and weight
to save maybe 4 quarts a year?  Or Am I missing some other value? 

Sincerely,
Fred N 9BF

PS... hope to see either you or your son at the GOLDEN WEST
FLY-in again this year.


[I don't think the issue is so much the saving of 4 quarts of oil per
year as it is keeping a major portion of them off of the airframe.  I
get the impression that most folks who use an air/oil separator don't
plumb its outlet back into the oil supply system, but rather collect it
in a catch can which can be emptied at the time of each oil change.  This
keeps the other possibly deleterious by-products that exit the breather
from being recycled through the engine once again.  This practice also
simplifies the oil system plumbing considerably, as a simple tygon line
can be run from the sparator to the reservoir.
