DURING CLIMB OUT TO CRUISE ALTITUDE THE PILOT NOTICED A DROP IN MANIFOLD PRESSURE AND A LOSS OF OIL PRESSURE. THE PILOT WAS IN THE PROCESS OF ATTEMPTING TO REACH AN AIRSTRIP WHEN THE OIL PRESSURE DROPPED TO ZERO FOLLOWED BY A TOTAL LOSS OF POWER. AN OFF AIRPORT LANDING HAD TO BE MADE ONTO SAGE BRUSH. FAA INSPECTORS DISCOVERED A HOLE IN THE CASE OF THE ENGINE. THE BEARINGS TO THE TURBOCHARGER WERE FOUND TO HAVE BEEN EXCESSIVELY WORN. THERE WAS OIL ON THE SPRING SIDE OF THE PISTON TO THE TURBOCHARGER CONTROL VALVE. THERE WAS ALSO EVIDENCE THAT THE PISTON WAS COCKED INSIDE OF THE CYLINDER TO THE POINT OF BEING WEDGED AND/OR OIL BYPASSING THE SEAL. THE TURBOCHARGER CONTROLLER WAS WORN AND HAD NOT BEEN REPLACED WHEN THE TURBOCHARGER HAD BEEN REPLACED SOME 10 FLIGHT HOURS AGO.
