B757-200 FO FOUND A FLUID LEAK ON #1 ENG ON EXTERIOR PREFLT INSPECTION.

Narrative

THE FO MENTIONED TO ME THAT DURING HIS EXTERIOR PREFLT INSPECTION; HE NOTICED THAT THE L ENG WAS DRIPPING FLUID. I ASKED HIM IF HE THOUGHT THAT IT WAS EXCESSIVE AND HE SAID HE COULD NOT MAKE THAT DETERMINATION. I TOLD HIM TO CALL MAINT AND HAVE THEM CHK IT FOR US; WHICH HE DID. I THEN LEFT THE ACFT TO GO TO THE GATE. WHEN I GOT BACK HE WAS DOING AN ENG RUN WITH MAINT ON THE HEADSET ON THE GND. WHEN THAT WAS COMPLETE; I ASKED HIM WHAT HAD TRANSPIRED. HE SAID MAINT HAD CHKED THE ENG AND EVERYTHING WAS OK AND WE DID NOT NEED A WRITE-UP IN THE ACFT MAINT LOG. WE THEN TOOK OFF AND PROCEEDED TO OUR DEST. I GOT TO WONDERING ENRTE IF WE SHOULD HAVE MADE A LOGBOOK ENTRY. I CONSULTED WITH THE MAINT PROCS THAT WE CARRY ONBOARD TO SEE IF I COULD GET SOME GUIDANCE. IT ONLY MADE THE CONFUSION WORSE. BECAUSE MAINT WAS CALLED I THINK MAYBE A WRITE-UP WAS REQUIRED; BUT SINCE NO PROB WAS FOUND AND NO CORRECTIVE ACTION TAKEN I DO NOT BELIEVE A WRITE-UP WAS REQUIRED. THE INFO IN THE MANUALS THAT I HAVE IS NOT CLR AND ALLOWAS FOR MANY GRAY AREAS. I FEEL THAT THE FAA'S INTENTIONS AND REQUIREMENTS SHOULD BE MADE VERY CLR.
