## Discrepancy

PILOT REPORTED LOW OIL PRESSURE WARNING SOUNDED LEFT ENGINE, AND GAUGE INDICATED ZERO OIL PRESSURE AT APPROXIMATELY 'GEAR-UP' TIME OF TAKEOFF.  LANDING WITHOUT INCIDENT.  TROUBLESHOOTING DETERMINED TO BE FROZEN BREATHER.  THIS SYSTEM HAS AIR/OIL SEPARATOR.  PIPER IS IN PROCESS OF MODIFYING SYSTEM.  ALL OPERATORS OF SENECA V AIRCRAFT SHOULD C/W THIS MODIFICATION WHEN AVAILABLE.  ROUTING OF LT ENGINE BREATHER IS SLIGHTLY DIFFERENT THAN RT DUE TO AIR CONDITIONING COMPRESSOR BEING MOUNTED ON LT ENGINE.  A LARGE PUDDLE OF OIL WAS FOUND AT LOCATION OF GROUND RUN.  OIL WAS BLOWN THROUGH RETURN HOSE FROM SEPARATOR TO ENGINE.
