## Discrepancy

AT HIGH RPM, THE OIL PRESSURE GAUGE WAS READING PAST THE RED LINE.  ENGINE OIL PRESSURE WAS CHECKED USING EXTERNAL GAUGE FOUND TO BE WITHIN MANUFACTURES LIMITS.  OIL PRESSURE GAUGE WAS REPLACED.  THE OLD GAUGE WAS INSPECTED AND NOTHING COULD BE SEEN CAUSING THE PROBLEM.  OIL PRESSURE LINE WAS CLEANED OUT AND NOTHING WAS FOUND IN IT OTHER THAN OIL.
