I'm at the firewall forward stage on my RV-8 and trying to get a handle on how an IO-360 oil system works. I see quite a few posts around where folks describe using various covers or shutters in winter to reduce the effective area of the oil cooler in order to get engine oil temperatures up to normal operating values. I was under the impression that the Lycoming engine has a vernatherm that regulates the flow of oil through or bypassing the oil cooler to some degree (like the thermostat in a car cooling system).
Why the need to cover up the oil cooler if there is a valve to reduce flow?
Are the fitted valves ineffective even if operating correctly?
Would a thermostat spiced into the oil cooler lines be an alternative to plates or variable shutters?
Thanks for any info you can offer.
