Steve (and all),
Interesting way to measure your oil consumption, but hard for us to
know how to compare that without knowing at what speed your aircraft cruises.
At 50 mph that would be 9 hours per quart and thus great oil consumption.
However, at 150 mph that would be 3 hours per quart - nothing to brag
about.
My 3300 Jabiru (in a highly modified Esqual - N31BZ) has 575 hours in
3 &1/2 years. From memory, It is serial number 843 and has solid lifters.
Most recent annual had compressions all between 70 and 74, and that was
measured with the engine cold. I figure I could have added a pound or two of
compression if I had done the compression check on a hot/warm engine.
There are no signs of oil seepage anywhere on the engine.
I generally run my engine rather hard (read that as a little above
2850) and my cross country cruise speeds at altitude always work out to 160 to
165 mph true airspeed burning about 5.8 gph. I also seem to "miss my
Pitts" and more than occasionally am at rather "steeper" bank and climb angles,
but have never noticed a hot oil smell that you mentioned. I change oil
and filter every 25 to 30 hours and generally find the "slobber pot" about
1/3 full at each oil change. Since completing the engine break in I have
used only Aeroshell W 100 Plus. I keep the oil level between the half full
mark and the bottom mark on the dip stick. My best guess on my engine's oil
consumption is probably about 1 quart in 7 to 8 hours.
Blue Skies,
Buz Rich

Thanks, Gary...it really helps figure out what may be going on with
the engine if we would all post the serial number when we request
help....kinda like going to the doctor. He/she always needs to know
your age.
I'm not familiar with the Kolb...is it a pusher or tractor set-up?
Does your oil vent line run uphill right after the dipstick tube
attachment, then down to the bottle? And is the Kolb an exposed engine?
My Kitfox is an enclosed cowl, tractor, and only requires about 10 oz
of oil addition between 25 hour oil changes.

Thanks, Chris. On another group, they suggest putting all pertinent
data regarding the aircraft in your signature. (Of course, if you're
writing to your girlfriend, you can delete all the airplane stuff.)
That way, someone that may be able to help or comment, will know what
engine they are dealing with. Saves some dummy like me from having to
ask. Also, knowing the type of plane the engine is in helps too.

All,
i have just re-torqued my head bolts ( 84 hrs TT on 3300A ) to 20 Ft./Lbs as instructed
and found 3 cylinder bolts at the 6 o'clock position just a hair loose.
it took less than an inch of rotation to click the torque wrench.
i was wondering if anyone else was experiencing this situation. also the bolt just
above it on the exhaust side of 2 cylinders did the same thing. i have all
cylinders at cruise CHT's under 300 deg. except No. 2 and it runs about 310.
(working on it )
thanks for any info,
Bobby

Bobby,
According to the Jabiru USA website the maintenance torque of the head
bolts is 22 ft-lbs.

20 ft lbs is correct it was revised a few years back and is in the current maintenance
manual, although 22 is close enough.
In practice, on my engine some bolts move and some dont. The hex head ones exhibit
less stiction whereas the capscrews often need a sharp pulse to break the
setting. Jabiru instructions are NOT to back any bolts off to reset torque, therefore
its a personal judgement as to how far you want to bump the torque over
20 ft lbs to be able to move the bolts to the correct setting. The lowest capscrew
which is accessed via the NPT plug is the one that needs the most attention,
so dont miss that one.
Your results at 84 hrs seem normal enough. You only do this operation 50 hourly.

Not a 3300, but my 2200 exhibits the same 6 o'clock position lower
torque readings.
(I wonder when the term "xx o'clock position" will fade from memory
as the new generation of kids brought up on digital time won't know
what that means)

Good point Buz.
I dont run my engine hard. RPM are often around 2,500. I fly at about 100 MPH
so that's a quart about every 4.5 hours.
My plane is a Zenair zodiac XL N601WF.
By the way, nice looking plane you have there.
Steve

Thanks, Steve,
Our EAA chapter built a 601XL (N156WT) that has a 3300 Jab on it. Has
been flying a little over two years and I think it has about 250 hours on
it. I will have to ask the current owners about their oil usage.
Blue Skies,
Buz
