Narrative:

October 2012; I was assigned to work a B767-300 aircraft that had a maintenance entry of a # 1 engine oil pressure indication problem. I found the oil press transmitter faulted. We replaced the transmitter per maintenance manual (M/M) and accomplished an [oil] leak check as required by the M/M. The flight crew ran the engine on the gate and no leaks were noted. I was made aware that this aircraft had a flight interruption and returned to ZZZ with a problem with engine oil loss in flight.
