Air Wolf oil /air separators

[aviatoreb]

According to one popular aviation columnist, running an oil separator is like "hooking a tube from your butt to your mouth".  I think he was referring to the acids in the blowby getting recycled into the crankcase. 

 

Haha - I have never heard that one.  Nuf said.  But let me guess who - Deakins?  He is a colorful writer.

Deakin may have said something like that, but I know I've heard Mike Busch make that remark.

I was talked into a air oil separator on my 231. All it really did was help cover up an engine issue. When the engine blew out 6 quarts in less than an hour it got replaced. As a Rocket it never had or needed a separator. The MSE does not have nor will ever get one as long as I own it.

I've heard Mike Busch use that line in his talks.

took the airwolf off my eagle. I always had moisture on the filler cap on the underside and it was starting to rust. When I took off the line that returns the oil to the engine it was full of snotty oil. Horrible crap to be putting back in the engine. Now cap has no more moisture. Sure, the belly gets slightly more greasy, but would rather have that than put that snot back in my new 310 hp engine!!!!!

At last annual, I installed a M20 air/oil sep except the output I put into an empty water bottle.   17 hrs later I have only 2 drops of oil in the  bottle so next time I'm in there we're taking it out and putting the original hose/tube back in.  Found a good size oil leak on the prop governor fitting.

most healthy engines will find their own oil level where they are happy. If that is in the operating range, run it there. If it starts blowing out oil spend money on fixing the problem, not an expensive band aid.

Mine seems to lose anything above 6.5 pretty fast, and below that, it goes through a quart every 6-10 hours. Much of this is burned, some is on the belly.
