--> Engines-List message posted by: "Mike Larkin" <mlas@cox.net>
Check between the cooling fins very closely. I was dealing with a
customer with a Cardinal that had a similar problem and we tried
everything without success. We found that during the casting and
painting of the cylinders that some of the cooling fins had some
blockages and rough edges. It didn't seem like much at the time but we
cleaned them up to get better air flow and the CHT came down 60-80 deg,
all that by just smoothing and cleaning up the cooling fins.

Dave -
Have you carefully checked the location of the EGT probe and its
relative orientation to the others? You didn't mention the CHTs of all
cylinders. What are they? It doesn't SOUND (emphasised because we need
more data) like a mechanical issue as much as an sensing/indication
issue. Did you swap EGT probes? The location of the probe in relation
to the flame front from the exhaust port is really important on a
RELATIVE basis. Whose system are you using? How did the plugs look
relative to the other cylnders? A standard compression check, performed
on a warm engine, will also tell us a lot. JBB

cylinder is my hottest for both egt/cht with egt at times 300 deg hotter

changed injectors with no change, changed plugs & range no change,
checked baffling, closed off oil cooler behind #4 cyl (to check baffling
also)no change. Some have suggested a possible exhaust valve leak.
Would this show up on a compression check with a cold engine or does it
need to be warmed?

Hi Mike,
I'm watching for your propeller delivery pretty close myself.
MT Propeller had been giving me a 10 week delivery time for most of this
year. Then they gave me a six week delivery time for your propeller. About two
weeks quicker than their shortest normal delivery time. Go figure.
They said they had a space open on their schedule, and could complete the
propeller on time. I believe your propeller delivery is waiting for your
governor. I should have an update from MT Propeller this Friday. (Thursday is
a
national holiday in Germany.)
For deliveries of customers propellers to myself for assembly, sometimes the
first delivery notification has been the arrival of the boxes. UPS is
faster than a FAX machine? :-)
Regards,
Jim Ayers

I am trying to remove the oil sump and accessory case from a Lycoming 0-235.
I took out all the bolts but the gasket is holding it together pretty good.
Does anyone have any techniques for causing it to separate without scoring
the mating surfaces?
Joe.

I don't know the specifics of that engine, but on others I've been able
to tap the part gently with a soft mallet and break the gasket loose
once the bolts are completely out.

I tried that with a leather mallet (a sledge hammer with a head like a dog
chew bone). I didn't hit it very hard for fear of cracking the housing. I
figured I should ask the experts before pounding away like a cave man.
I was wondering if there was a secret kung-fu pressure point to aim for. Or
maybe a Lycoming pry apart tool #2o02587a9sa87.... .
My next attempt would be to try to delaminate the gasket with a single edge
razor blade. Any suggestions?

On the stubborn ones, I use a putty knife, and tap it in
all around the cover/sump, etc. A bit at a time, with each
application 180 deg from the last.
Takes a little time, but always works.

Joe, The rear case has 2 5/16" dowel pins. recomend loosen pan bolts, the it
should come out easier. You might even save the pan gasket. -----Wes-----

I have a Bendix S4LN-204, Part # 10-163045-3 that has a circumferential
crack right where the gasket mates to the accessory case on this Lycoming
0-235.
I wonder if anyone out there has a replacement housing? Alternatively, if
someone could tell me the material of this casing so I can have it welded.
Is it aluminum, magnesium, or what?
Thanks,
(This was apparently caused during shipping when the mag was hit from
behind. The blow pushed the mag into the accessory case, cracking it too.
But the accessory case looks repairable. The reason the accessory case
cracked was that the 2 bolts holding the accessory case to the engine, these
are the only 2 bolts that go in from the prop side, were missing. Therefore,
the mag pivoted about the virtical axis and applied pressure the the inner
portion of the case. The 2 missing bolts left nothing to restrain this
motion.)
