Narrative:
I performed a transit check on a B727. I svced all 3 engines. The flight crew reported that the #2 engine oil indicator read 3+ gallons before their flight, and read zero upon landing. They never shut the engine down, due to positive oil pressure. In the corrective action, the mechanic indicated that the oil cap on the #2 engine was not secure. He svced the engine and released the aircraft.
