Looking at the location of the oil temp probe installed in the Lycoming oil filter adapter housing it appears that the temperature readings is essentially the temp of the oil as it enters the engine...if true this does not seem to be very helpful information.
When the Vernatherm is cold a great percentage of the oil is allowed to bypass the oil cooler and therefore the oil temp probe is pretty much reading the temperature of the oil that was just sucked out of the oil pan.
Then as the oil heats up the Vernatherm begins to extend and the tip blocks off the oil cooler bypass passage and then oil is forced to go through the oil cooler and when it returns to the oil filter housing if flows past the temp probe where the temperature is measured...in other words the temp probe is reading the temp of the oil AFTER it has already been cooled off by the oil cooler.
In car engines you measure the coolant temperature as it is leaving the engine and that makes the most sense to me...because you can indicate what is happening inside the engine.
Would it make more sense to know how hot the oil is really getting by measuring the oil temp at a location before the oil cooler?
On Continental engines do they also measure the temp of the oil after it is cooled?
Any information would be greatly appreciated
Thanks
