2001 FORD F SUPER DUTY Engine And Engine Cooling Problems

WAS SITTING AT STOP LIGHT, AND ALL OF A SUDDEN THERE WAS A POP, AND THIS TERRIBLE NOISE STARTED COMING FROM ENGINE AREA. PULLED INTO A PARKING LOT, AND CALLED MY HUSBAND. HE CAME DOWN, AND INSPECTED THE ENGINE. HE FOUND THE NUMBER 4 SPARK PLUG MISSING. THIS IS THE FIRST TIME THIS FAILURE HAS HAPPENED. HAD TRUCK TOWED TO A FORD DEALER, AND THEY INSTALLED A SPARK PLUG INSERT, AND REPLACED SPARK PLUG, AND COIL. $424.52 WAS TOTAL REPAIR BILL WHICH INCLUDED TOWING. OLD PARTS ARE NOT AVAILABLE. *TR

MY 2001 FORD F350 SUPERDUTY EJECTED A SPARK PLUG FOR THE SECOND TIME IN A YEAR. I FINALLY HAD TO BUY AN INSERT KIT TO FIX THE PROBLEM MYSELF COST ME 450.00 PLUS A NEW IGNITION COIL FOR 55.00. FORD WOULD NOT EVEN THINK OF TAKING THE BLAME FOR THIS PROBLEM TELLING ME THAT IT IS VERY UNCOMMON FOR THIS TO HAPPEN???????I DIDN'T HAVE A FIRE BUT I DID SEE SOME SMOKE AND SMELLED GAS VAPORS WHEN THE PLUG EJECTED IT ALSO SCARED THE HELL OUT OF MY WIFE AND I..IF IT HAPPENED ON THE INTERSTATE THERE COULD HAVE BEEN AN ACCIDENT FROM THE LOSS OF POWER AND THE SUDDEN SHOCK FROM THE NOISE.. I REALLY THINK THIS FAILURE IN THE FORD TRITON MOTOR SHOULD BE LOOKED AT CLOSELY AND MAKE FORD RECALL THESE ENGINES....THANK YOU DAVE CURTIN *TR
