It’s a great question. Air-oil separators are a bit of a mystery to me as well. I too would like to read the brain trust opinion on this device.

I installed Airwolf air oil separators on my 1982 Seneca III a week ago. I was looking for anyone who has had experience with using Airwolf or any other brands of air oil separators. I purchased my Seneca 5 months ago. a 300 hour and 1700 hour engine on TSIO360-KB with turbo chargers. 220 hp. I was getting oil coming out of the breathers. More out of the low time engine but I cleaned the bottom of the wing almost every flight. Very annoying but the mechanic said they have a tendency of breathing out oil. I did not have much consumption but amazed the amount on the bottom of the wing. By the way compression is good on both engines and there are no leaks on either engine. So I installed Airwolf separators flew a 2.5 hr flight and on decent I started loosing oil pressure. I was shooting an approach into low overcast with plenty of ice so I did not want to shut down engine. After landing I checked and was down to 2.25 qts in high time engine and low time engine down by 1 qt. Oil all over bottom of high time engine wing and puddle of oil at the base of the scat tube of the separator. Even the low time engine had oil under wing - again. After cutting open the filter and with no metal in filter I filled up oil, disconnected the separator on the high time engine and flew 45 min legs to verify oil and all seemed OK all the way back home and is currently in shop as they are trying to figure out what happened. Does anyone have any experience with this? good or bad?
Any info would be greatly appreciated. I know they have talked to Airwolf but with the Holiday around us not a lot of info yet but they said it was hooked up properly.
