On my new to me C170B the oil temp gauge was changed during the pre buy with a gauge from AC Spruce. It’s the standard thing that has a bulb that goes into the back of the oil screen like every small continental you’ve ever seen
it reads zero then at some point in the flight it jumps up to a normal reading. Sometimes takes 30 minutes. Sometimes longer. And once on the second flight of the day after it started working on the previous flight, it continued to work. I’ve tapped on it with no result. I guess it will have to be replaced but I’m curious to know what the failure mode is. I really don’t understand the principle behind how this type gauge works.
The old gauge that was removed is definitely dead.
Thanks
