| Subject: | Re: RE: oil Usage |
Thanks for the update, Gary. I removed my "puke jar" as I like to
call it, last week during my most recent 25-hour oil change. It had
collected 5 oz of oil and a *very* little bit of water...maybe 1/2 oz
out of that 5 oz. Then, because my puke jar/collection bottle is
translucent, I calibrated it at 2 oz intervals, and made marks on the
side. Now when I have the cowl off, I can make a note that at such-
and-such hours, I had collected "XX" oz of oil. This will help me
monitor engine wear, oil performance, etc.
During that 25 hours of operation, I only added 6 oz of new oil to
top off the oil sump.

I have used oil collection bottles in race bikes, they turn up to 15
thousand RPM and oil collection is still as simple as a small plastic
bottle. Oil will drop out of the vapour as long as you can slow the air
down, I'm confused about the requirement for vanes and traps, are you
flying inverted?

Lynn,
Built a separator, 5 vane 6" tall and insulated it.Last 2 hrs have
collected 1"of moisture in the catch bottle but no oil.Now I can keep
tabs on oil consumption.Finished a 4 vane 4" tall separator that I will
install this weekend.They look weird but it's effective.I'll just keep
making it smaller until it can't trap the oil.Here's a picture.

It may be the difference between your Kolb pusher, and my
enclosed-engine tractor Kitfox, but your plumbing sounds really
convoluted! This oil collection business doesn't seem to me to have to
be all that complicated, but of course in an engine-exposed environment
things will be different.
Keep us posted will you, Gary?

Dave,
?Not intentionally.On my early 2200a Jabiru requests that I run the oil level at
the add mark,to reduce pushing it out the vent.The add mark is 3/16" from the
end of the stick.Once it's below the stick it's hard to guess how much to add
to get it back to that level,so it's been see sawing between to much and not
enough with the excess ending up in the catch can.I'm just trying to eliminate
the loss out of the vent so I can get a realistic handle on basic consumption.The
separator just forces the vapor to make 4 or 5? 90 degree turns and the
oil drops out of the airstream onto the vanes and runs back into the sump.Unconfused?
????????????????????????????????????? Thanks,G.Aman Kolb MK-3C 450hrs mostly rightside

I read a good suggestion on one of the Jabiru groups that I
read....on top of the dipstick knob, you can see where the stick is
flush with the top of the knob. Simply drive the stick down through
the knob about 1/4"--3/8" , and you will have a longer dipstick...it
worked for me. On my stick at leaast, the knob is just "cast" around
the smooth stick. If they made one that was
knurled inside the knob, the knob might split when you drive it down,
but I doubt that Jabiru would go to the trouble/expense of another
machining operation on such a simple device as the dipstick.
