Subject: | Re: Overheating cylinder |
On a recent crosscountry flight at 8k and 2350 rpm, my IO360 started a wild
fluxuation on #2 cht. My Skyview showed rapid movement between 300 and 550
degrees then it went out of range and stayed that way until landing. While
taxiing all temps were normal and #2 egt stayed normal throughout the
flight. When I pulled the cowl nothing looked cooked and sensor wire
looked normal. Compression seemed normal when I pulled the prop through
eight or ten times. I will swap egt sensors 2&4 next flight. Any other
suggestions?

If everything there is OK try checking the injectors. Sometimes something
will get into the fuel injectors that causes the spray pattern to go bad.

Good thought, thanks. I will soak them in some Hoppe's #9. Would a
cylinder with a dirty injector really run that much hotter?

You won't have fluctuating values with a clogged injector. Only bad
probe wiring or a failing exhaust valve will cause rapid fluctation. In
the later case it will be a saw tooth pattern of maybe 50 degrees, and
your problem is far more likely to be a poor connection to the probe.

Thanks. Interesting that it cools down and becomes normal moments after
landing. But not on a long descent. Airflow thru cowl affecting poor
crimp connection. Will recrimp wires and clean injectors this weelend.
