## Discrepancy

NR 1 ENGINE FUEL HEAT VALVE OPENED IN FLIGHT AND COULD NOT BE CLOSED WITH NORMAL PROCEDURES.  THE ENGINE OIL TEMPERATURE EXCEEDED RECOMMENDED LIMITS, THE COM PROCEDURES WERE FOLLOWED AND A PRECAUTIONARY SHUTDOWN WAS ACCOMPLISHED.  FLIGHT DIVERTED TO DTW AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE FUEL HEAT VALVE WITH A SERVICEABLE UNIT.  SUBSEQUENT RUNUP AND CHECK WAS SATISFACTORY.  AIRCRAFT RETURNED TO SERVICE.
