Dick,

I fabricated a separator with a body of fiberlgass over aluminum. An return 
oil line leads from the bottom to a "1/2 inch pipe" fitting which is installed 
under the #5 cylinder in a hole in the block. The PVC is near the engine end 
of the return line and is installed so as to cut off due to pressure when the 
engine is running. To do this, I have the PVC at about a 45 degree angle from 
vertical to reduce the force needed to close the valve. I first tried it with 
the PVC on the bottom of the oil separator and in a vertical position; however, 
there was insufficient pressure to close the valve so more oil than ever made 
it out the vent.

Now when I fly the PVC closes and oil accumulates in teh separator body. when 
I shut down the valve opens and allows the oil to drain back into the engine.

I used an all metal PVC147 made by Deutsch and purchased at Autozone.
