## Discrepancy

RT. ENGINE, OIL TEMP REDLINE (HIGH), OIL PRESSURE LOW (REDLINE).  ATTEMPTED TO SLOW ACFT AND UNCONGEAL OIL COOLER. THIS DID NOT HELP. PERFORMED PRECAUTIONARY SHUTDOWN.  ON LANDING, MX INSPECTED FOR POSSIBLE OIL COOLER CONGEALING, DUE TO THE EXTREME OAT (-21°F). ENGINE OIL LEVEL WAS CHECKED AND WAS FOUND TO BE IN ACCEPTABLE RANGE. THE OIL FILTER WAS OPENED AND INSPECTED FOR CONTAMINATION, AND THE OIL STRAINER WAS INSPECTED - BOTH WITH NO DISCREPANCIES FOUND.  AS A PRECAUTIONARY MEASURE, THE ENGINE VERNATHERM, VALVE ASSY TEMP CONTROL, OIL COOLER BYPASS, WAS REPLACED WITH NEW.  AN ENGINE RUNUP FOR LEAK/OPS CHECK WAS PERFORMED WITH NO DISCREPANCIES FOUND.
