1999 FORD F SUPER DUTY Engine And Engine Cooling Problems

5.4L FORD TRITON ENGINE SPARK PLUGS WERE CHANGED AT 84,000, AT 110,128 SPARK PLUG ON #7 CYLINDER CAME LOOSE AND BLEW OUT. FUEL AIR MIXTURE COMES OUT THE SPARK PLUG HOLE WHICH IS DANGEROUS(HAS BEEN KNOWN TO START ENGINE FIRES). THERE IS A DESIGN DEFECT IN THE ALUMINUM HEADS NOT HAVING ENOUGH THREADS TO KEEP THE SPARK PLUG TIGHT. THIS IS AN EXPENSIVE REPAIR THAT FORD IS NOT PAYING FOR WHEN IT IS A POOR DESIGN WITH THE POTENTIAL OF IT CONTINUING TO HAPPEN AGAIN ON ANOTHER CYLINDER. *TR

ON MY F-250 SUPER DUTY THE #4 SPARK PLUS BLEW OUT CAUSING IT TO RUN BAD AND FUEL FUME TO ESCAPE THAT COULD HAVE CAUSED A FIRE. FRIEND HAS HAD THIS HAPPEN 3 TIMES SO FAR. I'VE ONLY DRIVEN 9,000 MILES IN THE LAST THREE YEARS BECAUSE OF THE SAFETY ISSUE AND THE COST TO REPAIR IT EACH TIME IT HAPPENS AT OVER 1000.00 DOLLARS A HOLE X10 THAT UNCALLED FOR AND UNSAFE. *TR

AT ABOUT 55,000 MILE THE ENGINE BEGAN TO RANDOMLY STOP. IT WOULD START RIGHT BACK UP. THIS USUALLY HAPPENED WHEN ACCELERATING FROM A STOP. AFTER A WHILE IT BEGAN TO HAPPEN MORE OFTEN AND NOT RESTART RIGHT AWAY. AFTER HAVING THE TRUCK LOOKED AT, I REPLACED THE CAMSHAFT POSITION SENSOR (CPS). I AM UNSURE IF THE OLD PART IS STILL AVAILABLE. *TR

AT LOW SPEED, SPARK PLUG BLEW OUT OF ENGINE, CAUSING LOUD EXHAUST NOISE AND GASOLINE FUMES WERE IMMEDIATELY SMELLED INSIDE PASSENGER COMPARTMENT. IF THIS WERE TO HAPPEN AT HIGH SPEED WITH ENGINE UNDER LOAD WHEN IMMEDIATE ENGINE SHUTDOWN WAS NOT SAFE OR POSSIBLE, THIS CONDITION WOULD CAUSE LARGE AMOUNTS GASOLINE/AIR MIXTURE TO BE EXPOSED TO HOT EXHAUST COMPONENTS, CAUSING FIRE HAZARD. IF THIS OCCURRED WHEN POWER WAS CRITICAL (PASSING OR TURNING IN FRONT OF TRAFFIC), THE LOSS OF POWER COULD ALSO CAUSE AN ACCIDENT. IF THIS OCCURRED WHEN DRIVING ON SLICK ROAD CONDITIONS, IT COULD CONTRIBUTE TO LOSS OF CONTROL OF VEHICLE. THIS IS CONSIDERED A "HEAVY DUTY" ENGINE, BUT DOES NOT USE A HARDENED THREADED INSERT IN THE CYLINDER HEADS TO STRENGTHEN THE THREADS THAT THE SPARK PLUGS SCREW INTO. SEARCHING ON THE INTERNET FOR (TRITON BLEW SPARKPLUG) REVEALS THAT THIS IS NOT AN ISOLATED INCIDENT. ALSO, THE MANUFACTURERS TORQUE SPECIFICATION FOR THE SPARK PLUGS IS QUITE LOW - PROBABLY DUE TO THE ALUMINUM THREADS IN THE HEAD. THIS COULD BE A CAUSE FOR THE SPARK PLUGS LOOSENING. *AK
