Had an interesting thing happen on a flight from AZ to
So Calif. Cruising at 14500ft had been in cruise about
40 min. was running 2600RPM 31"  18GPH about
75 deg. LOP. The temp on #1 cylinder went from 315
to 500 oil pressure dropped to 15 oil temp went from
178 to 197. I went full rich reduced power to 17" and
went to nearest airport to land, this action brought
temps back into normal as well as oil pressure to 38.
On the ground I removed the top cowl to be sure there
where no oil leaks and found non. Refowled plane
took off and did some laps in the pattern everything
normal started home and at 8500 ft and 30 minutes later
same thing CHT 425 oil pressure 21 oil temp 174. I had been flying at 2500/22". I reduced power again and temps
came back down, I continued home. I since have removed
the cylinder and have had it inspected by 2 competent
mechanics and no damage. The engine has 260hr.s, does
anyone have any ideas as to the problem?. Your thoughts
and ideas would be appreciated
