Consumer Description

DRIVING FROM DALLAS, TX, TO WEST LAFAYETTE, IN, IN JAN 2010, THE 2002 MERCURY MOUNTAINEER WITH 4.6L V8 ENGINE BLEW A SPARK PLUG OUT OF THE CYLINDER HEAD CAUSING US TO STOP IN A SMALL TOWN TO HAVE THE ENGINE REPAIRED. THIS WAS A FACTORY INSTALLED (NOT REPLACED) SPARK PLUG. I HAVE SEEN MANY COMPLAINTS ABOUT THIS IN THE FORD V8 ENGINE. THE VEHICLE HAD AROUND 86,000 MILES ON IT AT THE TIME AND WAS NOT DUE FOR A SPARK PLUG REPLACEMENT UNTIL 100,000 MILES. THIS WAS A SAFETY HAZARD AS GASOLINE IS SPEWING OUT OF THE CYLINDER HEAD WITH AN ATTACHED AND STILL ARCING SPARK PLUG. *TR
