'If the oil pressure is normal there is essentially no way you can have an above redline oil temp.'
I afraid that there is a way. I took off on a very hot summer day and climbed to 2000'. As I levelled off I noticed that the oil temperature was rapidly approaching red. I returned to the airfield and we found that the carb heat cable had frayed and stuck carb heat at about half. This was not noticable from the knob which was fully in.
