C172 engine overheating question

[ppragman]

What would cause a lycoming 0-320 engine to overheat under these circumstances?

-oil is filled 7qt's with 100+ oil
-oil pressure in the green always
-just had oil/filter change 14 hours ago
-engine cowling is free of obstructions


Any ideas?

Lower the nose...

But seriously, it sounds like the guage, try swapping the guage and then runthrough a routine of slowflight, and stuff to get her hot, and see what happens.

btw, what happens to the engine with power at idle

I swapped aircraft a few days ago with another Cessna and this one has zero problems. With the aircraft in question, when I would pull to idle the engine would idle smoothly with no problems and oil pressure would remain in the green.
