Rear Oil Temp

[Bob Cook]

Paul

Is it a "P" ?

I would check the oil bypass thermionic valve. The one that allows the oil to pass thru the cooler.

2) oil cooler may be plugged.

3) baffles incl the baffles around the oil cooler.

4) Oil temp guage and not the sending unit. I think you can find test strips that will change color and you just stick them on the crankcase or cooler. The color determines peak temp.

5) swap the guages from front to rear for the test or stick the oil temp sensor into boiling water and see if it reads 212 degrees F.

6) You didn't tell us what the temp is reading.

7) does it change or remain the same ? in climb? full rich ?

lots of questions need to be clarified.
