Narrative:

Was approximately 5 mi southeast of ZZZ1 when oil temperature begin to rise and oil pressure begin to drop. Turned northwest to attempt to locate ZZZ1 airport. I could not locate it and flew toward ZZZ. Engine began to lose power and at an altitude of 800 ft I decided to make a precautionary landing on a field. Upon rollout the nose gear hit a rut and collapsed. There was no damage to the field or crops or injuries to myself. The engine has not been turned down yet to find the problem, but it is probably an oil pump.
