Narrative:

I got an oil filter bypass light on #2 engine with rising oil temperature. Light remained on when throttled to idle. Declared an emergency and diverted to oma where a landing was made with the #2 engine remaining at idle due to reported possibility of low level turbulence and windshear. Landing was uneventful. Callback conversation with reporter revealed the following information: the reporter flies the B737-300 with cfm 56-3 engines. It is normal procedure to shut down, or at least idle, the engine to 'prevent further damage.' metal was found in the oil screens and the engine had to be changed.
