I have recently acquired an RV-8 with an angle-valve IO-360. At lower OATs (below 60?F?), I find it takes inordinately long to get the oil temp up. I prefer to get up to 150-160?F, especially when doing formation TOs that require lots of throttle jockeying. At those temps, I'm seeing 90-100 PSI at 2700 RPM. Temp regulation in flight appears to be normal and cruise numbers for temp and pressure are good.
SO... I thought I understood the operation of the Vernatherm valve. But to more expert guys - Is there a failure mode of the Vernatherm that would not bypass the cooler at lower temps, ie. always have the oil cooler in the circuit? (At home base, I know I can install and use a sump heater, but sometimes when out X/C there is no power available.)
Thanks,
