Air / Oil Separators

Anyone install an air oil separator?

Which one did you install? Does it work?

Airwolf

I was once in a partnership with a 206. It had a stock air/oil separator (don't remember which one) but after it cracked TWICE (how does that happen? :dunno:) and we got tired of the incredibly oily belly we installed the airwolf separator after seeking advice on the Cessna Pilots Association website. HUGE improvement.
 
Airwolf, yes - as long as there isn't too much blow-by

Blow-by can be measured using an airspeed indicator - it sounds kludgy but at least it allows some measurement & characterization of the system
 
If it is for an experimental I would install one of these...

Keeps the belly squeaky clean,, and helps in the performance of the motor... There is a cheapskate certified aircraft owner here that has the brand that collects blown out oil in a can mounted on his firewall and then he pours that crap back into the motor.. He swears it is perfectly clean and OK to do..:hairraise::eek::yikes:...

I have a separator of unknown brand which was on the Lancair. It is a big round can with a drain at the bottom for oil return to motor and a hose at the top which is routed to the spark arrestor referenced above. The spark arrestor is routed into the exhaust pipe through an adapter here:

Of course they also sell the whole thing:

These will build hard crusty baked oil at the opening to the exhaust which could conceivably occlude the vent pipe leading to a pressurized crankcase. To avert this possibility some recommend a "whistle slot" be cut in the top of the pipe leading out of the air oil separator to the spark arrestor.

It works well to keep oil off the belly. Over time it will cause a bit of a soot covered belly but much slower than without the separator and spark arrestor being routed into the exhaust.
 
We have AirWolf on the 310 and have been happy with them. Once there's too much blow-by, they quit being effective.

He must close his eyes when the water starts draining out.
 
Had the air wolf filters. Worked great
