A B737-200 CAPT RPTS AFTER LEAVING THE SCHEDULED FIRST ACFT DUE TO A HYD AND ENG OIL LEAK AND BOARDING THE SECOND ACFT HE WAS PRESSURED TO TAKE THE AIRPLANE WITH THE R ENG LEAKING OIL.

Narrative

THIS WAS THE SECOND ACFT OF THE MORNING PRIOR TO THE FIRST PUSHBACK OF THE DAY. OUR FIRST ACFT (NOTICED BY FO ON WALKAROUND) HAD A HYD LEAK ON THE R WING; OIL LEAK FROM THE #1 ENG. THE MECH SAID IT WOULD BE 1 1/2 HRS; SO BETTER DEPLANE. I THEN WROTE UP BOTH ITEMS AND LEFT FOR OUR SECOND ACFT. TO SPD THINGS UP; THE FO WENT RIGHT TO THE WALKAROUND AND I DID THE INSIDE. THIS TIME THE FO NOTICED AN OIL LEAK ON THE #2 ENG. I WAS JUST AT THE POINT IN MY PREFLT OF LOOKING THROUGH THE LOGBOOK WHEN A MECH CAME IN AND ASKED TO SEE THE LOGBOOK. HE DISAPPEARED WITH THE LOGBOOK OUT THE DOOR. THE FO THEN RETURNED TO THE COCKPIT TO RPT THE OIL LEAK ON THE #2 ENG TO ME. THE MECH CAME BACK IN THE COCKPIT AND SAID THAT THERE WERE NO REPLACEMENT ACFT AND THAT IF WE GNDED THIS ONE; THE TRIP WOULD HAVE TO BE CANCELED. IN ADDITION; HE SAID THAT IT WOULD BE OK TO TAKE THE ACFT BECAUSE THE 'ACFT REALLY DOESN'T NEED MUCH OIL.' HE SAID HE HAD AN ACFT LOSE OIL DOWN TO 1 GALLON AFTER TKOF DUE TO THE OIL CAP FALLING OFF AND 'THEY MADE IT THE WHOLE WAY ON AN ETOPS FLT!' HE SAID HE WOULD HAVE THE ACFT PUT ON AN OIL CONSUMPTION WATCH AT THE END OF THE DAY 'IF' WE TOOK IT NOW. THERE ARE SO MANY THINGS WRONG WITH THIS CONVERSATION THAT IT'S HARD TO LIST THEM IN THE SPACE PROVIDED: 1) I DON'T CARE HOW MANY ACFT ARE AVAILABLE FOR REPLACEMENTS. 2) I AM HOPING THIS MECH DOESN'T THINK IT'S OK FOR A CAPT TO LOSE DOWN TO 1 GALLON OF OIL; AND THEN CONTINUE TO DEST -- BECAUSE SOMEONE MADE IT THERE OK. (I HAVE NO IDEA IF THIS IS A TRUE STORY.) THIS STORY IS NOT RELEVANT TO THIS DISCUSSION IN ANY CASE. 3) ALL I AM LOOKING FOR IS IF THE MECH LOOKED FOR THE SOURCE OF THE LEAK; AND IN HIS JUDGEMENT IT IS OK TO GO. HOW CAN I TRUST SOMEONE'S JUDGEMENT WITH THE ABOVE STORY AS BEING OK? WE ENDED UP TAKING THE ACFT; BUT JUST THOUGHT THERE NEEDED TO BE DISCUSSIONS BTWN FLT OPS AND MAINT.
