I recently had a factory rebuilt engine installed. I have since put about 70 hrs on the new engine. It was getting up to 220 right after install so we had the oil temp sensor and vernatherm replaced. Now the oil temp is consistently 200-210. Is that normal? I don’t remember what it was reading before the new engine, but thinking it was more like 180-190 in cruise.
KAUO - KEPC
OAT - 16
Alt - 6000
Power setting - 71%/2500rpm
Fuel - 17.1
My engine (IO550N) has about 1900hrs and will be replaced soon. But looking at my rececent flights, I always run at lean of peak and at 65%, my oil temp is 180deg at cruise with 13.1 gph fuel burn. It seems that your running rich of peak which would cause engine oil temp to run higher.
