RE: [COUPERS-TECH] Oil temp

[Mary Lechner]

Scott- I feel for you . My coupe had exactly same problem  in hot Sacramento summers till I did 3 things. (1) sealed oil tank cooling ducting where it contacts nose cowl (2) sealed air filter housing where it contacts nose cowl (3) made sure lower nose cowl had one-one & onehalf inch clearence at bottom of firewall. Mine touched & wore a hole in belly skin! Temps immediatly came back to normal(100 above ambient) A lot of us local coupers also use the finned cooling shroud  on oil filter which helps some. Two sources are JC Whitney & A/C Spruce. No need for cabin heat in Sacramento valley so I removed cabin heat shroud & related ducting.

Oil temps of 225 are routine Oil pressure 34 psi min   The only anomaly I see is that the diverter valve for cabin heat either diverts heat to the cabin or to the interior of the cowl, so essentially, there is a 1-5/8 dia leak path of cooling air from the left bank at all times     Flying and worrying about oil temp is not fun.   1.Are there any STC's for an oil cooler?         How well do they work? 2. Any body else having familiar with o-heating problems? 3. Is the larger opening nose bowl the solution?   I don't want to over cool in the winter, although our coldest winter day is 40 degree in So.Cal   Thank you           ============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm
