Hi All:

I have a relatively new Legacy flying with a Performance Engines IO-550.? The
airplane has been flying great and all engine parameters have been normal with
the (possible) exception of Oil Temp.

An example would be a flight yesterday from San Diego to the Marysville
fly-in.? Taking off early in the morning, the Oil Temp was as high as 220
degrees (F) by top of climb at 12,500' slowly reducing to about 213 (F).? The
return trip was about the same.? Although it was warm (ISA +30 at 12,000')
other Legacy pilots that I talked to said their oil temp never got above 170
(F). 238 degrees (F) is MAX.

Anybody else had a similar experience and/or solution?? Performance Engines
apparently has an Oil Cooler Adapter Kit that supposedly helps..... anybody
tried that?

Thanks... as ALWAYS.... for the help.
