John, Bud
I seem to remember that there was a lot of discussion of the best way to do
this back in 2002-3.
Attached is a picture of what I have been using on G-IANI (which is 914
powered but the same principles apply) for the last nine years. A simple
open top bottle.
It collects a little condensate (water) and a small amount of oil but never
more that about 15mm between services. I have never experienced any oil
staining round the bottle.
The bottle, chosen for its size and shape, came from a Halfords break bleed
kit and cost very little.
One important point is not to have the end of the drain tube (or top of the
bottle) in a low pressure area as this will make things worse.

John,
Not a bad idea on a 912S. All the Rotax's do spit a bit more oil when the
tank is full as on a cross country. My 914 doesn't spit much oil unless it
is full. A separator may do the trick. I saw someone with a simple screw
on can lid and brazed a couple tubes in it. The store bought ones all have
5/8 and 3/4 inch tubes and cost a bundle.
I am familiar with the Jabiru separators and they work well but they have a
5/8 nipple. Why not make a fiberglass can 2x2x4 with a 5/16 inlet and
outlet out of the top, coat it well with fiberglass resin to seal and bake
it at 250F for a bit to heat cure it. Cheap and simple... Bolt it on the
firewall and let the outlet dangle out the bottom as before.
Regards,
Bud

Subject: Europa-List: Oil tank breather separator
Dear Europaphiles,
I am doing some routine maintenance and note that as usual, I have quite a
lot of oily marks on the belly of my plane from the oil tank breather hose
---From my 912S.
I am curious if any of you have installed an oil breather/separator and if
this has been successful, perhaps you may be able to make a recommendation.
Cheers, John
