Subject: JabiruEngine-List: compression
While doing my "Condition" inspection I found that #3 cylinder had dropped to 56
/ 80 on the differential compression gauge ( engine warm ). The other five were
72, 74, and 76 average. The leak is through the rings because I can hear it
in the Crankcase breather line to the catch can. The next day ( engine cold
) I put a pressure gauge on the cylinders and spun the engine with the starter.
All cylinders were up to 90 psi or above including the #3.
The engine is not using oil excessively ( about one to two ounces per hour ) and
the oil is clean - about the color of maple syrup after 25 hrs on it. I sprayed
all the cylinders with Sea Foam Deep Creep and am letting it sit until I
get back there to run it and check differential compression again.
Has anyone dealt with this problem or know how to fix. I plan on flying it for
a for an hour or two and try the differential compression test again.
Thanks for any input.

Be careful with oil additives.=C2-=C2- For example, Avblend is not reco
mmended as it dissolves some of the sealants used between the case halves,
etc. I don't know about Sea Foam Deep Creep.=C2-Regards,

So, it was recommended to me to run the engine up in rpm fairly frequently to get
the cylinders hot Enough to keep things clean. (Burning off carbon)
Just my 2 cents

when doing the compression test,with the differential gauges,hang onto
the prop firmly move it back off of tdc and then pull it forward again
toward tdc.The rings act a little like wiper blades do but need to seal
in the groves and rocking a little promotes that action

I just ran the engine for about 5 minutes today without the cowl.
Did a differential compression test and #3 was back up to 72 / 80.
The soaking with Sea Foam Deep Creep ( Since Saturday ) worked though I could
still hear some air escaping thru the rings at the oil catch can.
Last week I had never heard of Sea Foam and tomorrow morning I am picking up 2
cans from the Auto Parts store.
One for home and one for the hangar.
Thanks to the guys that responded.

Running a Jabiru engine without the cowl on is a very risky proposition. More
than one person has trashed their engine doing just that. CHT's must be watched
carefully;airflow over the fins is a must.
If SeaFoam loosened the rings, then that might be a sign of an overheated cylinder.
Just my opinion.
