Chris, An old Lycosaurus trick is to put a slit in the breather tube so that
if there is any obstruction in the end of the tube the pressure will push
the slit open and allow the engine to vent.

John,
The oil fill tube,dip stick guide,crankcase vent are one and the same.About
3/4 in ID with the base of the tube not far enough above the oil level.The
later model engines have a deeper oil pan,but it really should have a wind
age tray like we used in VWs .I have built a separator mounted on top of th
e engine with 5 vanes in it that cause the vent gases to make sharp turns w
hen leaving the case that SEEMS to help,and have used a PCV valve to try to
hold a negative pressure in the case, but the venting system needs a redes
ign IMHO.If I still have it at the 2000hr TBO,I would try to modify it.It i
s such a sweet engine in other respects.

Chris A/Gang:
Is it mandatory to use a large catch can? or can you configure the breathe
r
hose to dump overboard?
Does the engine blow that much oil through the breather? or is the catch
can also the air/oil seperator?

Chris,
Glad you found the culprit!
My rather small air/oil separator has one inlet and two outlets. The top outlet
goes via flex hose directly overboard. The bottom outlet goes to a petcock and
from there it also goes overboard. After every flight, I drain the several drops
of the muck that collects in the bottom using the petcock. As long as I never
let the separator fill up (drain after every flight), no oil or muck comes
out of the upper outlet and the tail stays nice and clean.
I add no more than a 1/2 pint or so of oil between 50 hour changes, so most of
what comes out of the separator is oily water.

Thanks for that info. I have a better understanding of what the Jabiru
folks problem is now.
Is the Jabiru Factory doing anything to help with this problem?
Hopefully, you all can come up with a good solution.

ps...this is the picture of the catch can...i removed the Brillo pad
that was getting deteriorated and replaced it with paper toweling to
soak up any moisture and oil...I am back using A Brillo coarse mesh pad
again and I think I'm going to use larger diameter tubing too..when I
took it apart you could see where the toweling was right up against the
in-coming and out going openings...

>>>>>>>>>>>>>>>
if there was someway that you could put some insulation around the
seperator / tubing, it would keep it warm enough it could not ice over.
just thinking outloud here, i have seen some foam tape that would
keep things a bit warmer. as to paper or corse mesh pad... when
working with pnumataic thermostats and controls,, one of the best
filter housings ive seen used a roll of toilet paper as a filter
element. it worked as a filter dryer. and cheap to replace.
