THE TAKEOFF WAS ABORTED AND AFTER THE LEFT ENGINE WAS SHUT DOWN, OIL WAS SEEN LEAKING FROM THE LEFT ENGINE.  MAINTENANCE FOUND ONE END OF THE OIL COOLER BYPASS LINE LOOSE.  THE FITTING WAS TORQUED AND AREA CLEANED OF OIL.  ENGINE WAS GROUND RUN AND CHECKED FOR LEAKS WITH NONE FOUND.  ENGINE OIL QUANTITY SERVICED AND AIRCRAFT WAS RETURNED TO SERVICE.
