 Listers,
 
 Up here in Minnesota where it can get cold at times, in the winter it is
 sometimes a challenge to get the oil temp up enough for condensate removal.
 I modified the oil cooler door for a complete seal and still see temps in
 the 140 range when it is -25C at altitude.
 
 Twice this year I had the oil cooler congeal when it was -45C at altitude
 with partial oil pressure loss (once where the prop governor quit working),
 so basing a heater on the oil cooler discharge wont help when you need it
 the most.  I tried that as a fix for the lousy factory heat system on my non
 pressurized IV, but gave up once the oil temp issues were noted.
