Why go through the effort?
I got a real nice AndAire oil separator with the condensation collector with my Jabiru 3300. Worth $400 from ACS.
But with the Sonex, firewall forward space is very limited, especially above the motor.
So I understand the separator will extract the oil from the breather and collect it so it isn't dumped overboard and dirties the plane and environment. And the condesation collector removes the water from the frothy emulsion. But it isn't recommended to return that oil back to the engine. And its gravity fed so it would have to sit above the crank case.
So, I guess you just collect it in a bottle and dump it when it gets full.
Or, forgo the separator and clean the bottom of the plane every few flights.
Who uses these? Would you do it again?
