## Discrepancy

A FACTORY OVERHAULED ENGINE WAS INSTALLED.  ENGINE STARTED TO MAKE METAL.  WHEN OIL WAS DRAINED, IT LOOKED LIKE ALUMINUM PAINT.  AN OIL SAMPLE AND FILTER ELEMENT WERE SENT TO FACTORY.  FACTORY REQUESTED THAT ENGINE BE REMOVED AND SENT IN FOR REPAIR.  TIME ON ENGINE 63.5 HRS SMOH.  SUSPECT CAUSE WAS MISALIGNED CRANKCASE.  THIS CAUSED PISTON PINS TO SHIFT.
