## Discrepancy

(CAN) SHORT WHILE AFTER TAKEOFF OIL PRESSURE ON THE LT ENGINE STARTED FALLING BELOW THE GREEN.  RPM ALSO STARTED FALLING.  WHEN OIL PRESSURE CAME CLOSE TO RED LINE, PILOT PULLED FEATHER (PROP) & SHUTDOWN THE ENGINE. AFTER INSP OF THE ENG, IT WAS FOUND THAT NR 3 CYLINDER HAD LOW COMPRESSION & METAL FILLINGS IN THE OIL SCREEN & OIL FILTER. ENG WAS REMOVED FROM ACFT, REMOVED ALL CYLINDERS & FOUND THAT NR2 CYL INTAKE LIFTER HAD BROKEN OFF CAUSING INTERNAL DAMAGE TO THE ENGINE.
