is this by any chance the cylinder on which the stock cht probe
is installed? in my installation, (t-arrow iii), the stc on the
edm-700 required that the stock cht be retained (it's #1 on the
tsio-360fbfc). so on that cylinder, instead of a bayonet probe,
the edm-700 uses a "gasket" probe under the spark plug. the
gasket probes are notorious for reading high -- on my t-arrow,
#1 reads about 50 deg higher than the hottest of the other 5
cylinders. we've replaced the gasket probe to no avail. when
the jpi flags a warning in climb (470 degrees), the stock cht
still shows a good 16th or 3-32nds of an inch below the red line.
our a & p has checked the temps and found the gasket probe to
read high. so, at least in our case, it is a "false alarm".
don't know if the same is true for you, but you might want to
check it out.

Since a major overhaul about 60 tach hours ago now,
I've noticed my #3 cylinder (O470R, 182) is running
consistently hot. It is typically 30-40 degrees warmer than
the average, which puts it at 4-bars in the EDM700
display. To keep this cylinder temp down, I'm having to
leave the cowl flaps open in cruise, which slows me down
some 6knots or so. EGT's are all equal.

Does this indicate extra friction in that cylinder which could
be a problem? The engine as a whole is using about 1qt
every 15 hours or so now & I followed the Continental
break-in procedure to the letter. It's running great.

Did someone miss a bit of baffling in reassembly? Can
missing baffle really make that much difference?

Perhaps things will return to normal after a few more hours
and I should stop worrying. Comments?
