Narrative:

The night of dec/xa/00, I was assigned to open aircraft xyz #2 engine high pressure compressor inlet air shield borescope. After opening the motor and installing the turning tool for inspection, I assisted the welders with a turbine cooling line repair. Upon reinstalling the turbine cooling line clamps, I saw that inspection had completed the borescope and I proceeded to close the engine. Normally, after turning the motor for a borescope, I remove the turning tool and install the plug. Since inspection turned the motors themselves and removed the turning tool, I overlooked reinstalling the plug. I closed the engine and signed off the operation. The job inspection cards for the operation do not include a signoff for installing the turning pad cover. Flight crew wrote up a suspected oil leak on #2 engine 3 quarts low on arrival in XXX.
