I went for a flight yesterday which I experienced a very unusual oil temp for my plane. My temp has been steady between 180-200 depending on the season and OAT for this time of the year, 180-185 would be a normal temp.
Last week I was flying (short duration) and I saw suddenly a very high oil temp as I added some power to climb. Surprised by the high oil temp, I pull the power and the temp came down right away. I richened the mixture a bit and from there on, it looked normal.
Yesterday I went for another flight and as I took off, within a minute or so I saw my oil temp at 238, I immediately reduced power and decide to go back and land. As I pulled the power (reduced manifold) my oil temp immediately started coming down and when I added power to get into the pattern altitude, the oil temp would immediately go up. So I tried this two or three times more and the behavior was near instant as if the oil temp was controlled by the black knob. I landed and went back to the hanger to look things over. Took the cowl off and did not find anything abnormal. During the high oil temp, my oil pressure was unchanged at all, right around 77 PSI.
I made three separate flight after and all normal temp and could not get it to replicate.
The only change that I can think of is that I had updated my Garmin data base during the time this behavior had shown itself and I was wondering if the data base update could cause issue a bug in the OS to show itself?
My question is
- Has anyone else experience this
- Is it possible that this is an actual and true oil temp that is being reported? Could oil temp go up so quickly and go down so quickly.
- Could this be a probe issue? Again I am puzzled that it would be effected by the manifold pressure
- Could data base update cause a bug in the OS (I guess this is more of question for advanced users)
My avionics are all Garmin G3X and I am on version is 8.60
