WHILE DRIVING DOWN INTERSTATE STARTED TO HEAR A LOAD POPPING NOISE FROM ENGINE. IMMEDIATELY PULLED OVER TO FIND THAT ONE OF THE SPARK PLUGS HAD BLOWN OUT OF THE HEAD. HAD TO BE TOWED. STILL WAITING OF COST OF REPAIRS. RESEARCHING ONLINE, IT APPEARS THAT THIS IS COMMON ISSUE WITH THIS MOTOR. *TR

THE FAILURE AND CURRENT MILEAGE WAS 170,000.

I WAS DRIVING ON THE FREEWAY WHEN A POP AND LOUD "FLAPPING" SOUND WAS HEARD. I THOUGHT I HAD BLOWN A TIRE. THE TRUCK LOST A GOOD AMOUNT OF POWER AND WAS SHAKING WHILE CONTINUING TO MAKE THE "FLAPPING" SOUND. AFTER TAKING IT IN, IT TURNS OUT IT WAS A BLOWN SPARK PLUG THAT SHOT OUT OF THE ENGINE, DAMAGING THE BLOCK, PLUG, AND COIL. THE COST WAS $630 TO FIX IT. *TR

I HAVE A 2001 FORD F-150 LIGHTNING WITH ROUGHLY 31,000 MILES ON IT. THREE WEEKS BACK I WAS TURNING INTO MY NEIGHBORHOOD AT 5 MPH, AND I HEAD A POPPING SOUND, AND THE TRUCK BEGINS TO RUN ROUGHLY. I IMMEDIATELY PULL OVER, AND POP THE HOOD, I SMELL GASOLINE. I SHUT THE TRUCK OFF. CALL A TOW TRUCK TO MY FORD DEALERSHIP. THERE THEY TELL ME THAT THE SPARK PLUG HAS SHOT OUT OF THE CYLINDER HEAD, STRIPPING THE ALUMINUM HEAD. I GET THE BILL FOR REPAIR IN WHICH THEY RE-BORE THE HEAD, AND INSTALL A HELI COIL AT A COST OF $560 PLUS LABOR. THE DEALERSHIP TELLS ME THIS SHOULD IN FACT STRENGTHEN THE CYLINDER, SO I CONTINUE NORMAL OPERATION OF THE VEHICLE TUESDAY 5/17/11, I WAS DRIVING ON ROUTE 290 IN WORCESTER WHEN ALL OF A SUDDEN AT 70 MPH THE HELI COIL POPS OUT CAUSING ME INSTANTLY...

2001 FORD F150 SUPERCREW 5.4L. WHILE DRIVING THIS VEHICLE THE SPARK PLUG FORCIBLY CAME OUT OF THE CYLINDER HEAD. VEHICLE WAS NOT ABLE TO BE DRIVEN AFTER BLOWOUT OF SPARK PLUG. VEHICLE HAD TO BE TOWED TO GARAGE. NOT SURE HOW OR WHY THIS HAPPENED. *TR

SPARK PLUGS KEEP POPPING OUT OF CYLINDER HEAD. HAS HAPPENED FIVE TIMES SO FAR. I KNOW OF SEVEN OTHER PEOPLE WITH THE SAME PROBLEM! *TR

I HAVE A 2001 FORD F-150 WITH A 4.6 V8 ENGINE AND I HAVE NOW HAD 2 SPARK PLUGS BLOW OUT OF THE PASSENGER CYLINDER HEAD. THE TRUCK HAS 145,000 MILES ON IT. THESE DID NOT HAPPEN AT THE SAME TIME THEY WERE ABOUT 12 TO 18 MONTHS APART. THE SPARK PLUG HAD BEEN REPLACED OVER A YEAR BEFORE THE FIRST BLOW OUT OCCURRED. IT ALSO BROKE BOTH COILS ON THOSE CYLINDERS. UNTIL I STARTED A SEARCH TO SEE IF ANYONE ELSE HAD THIS ISSUE I WAS UNAWARE OF THE DANGER OF FIRE. *TR

WHILE DRIVING HOME FROM WORK I HEARD A LOUD POP COMING FROM THE ENGINE COMPARTMENT,THEN SOUNDING LIKE AN AIR COMPRESSOR. MY MECHANIC TOLD ME THAT ONE OF THE SPARK PLUGS BLEW OUT OF THE SOCKET AND NEEDS A HELICOIL INSTALLED TO HOLD THE SPARK PLUG. THIS FIX IS GOING TO COST ABOUT $300. HE ALSO STATED THAT THIS IS A COMMON PROBLEM IN FORD TRUCK ENGINES. AS OF YET THERE IS NO RECALL ON THIS PROBLEM! *TR

I HAVE A 2001 FORD F150 CREWCAB TRUCK. ON MY WAY HOME FROM WORK, MY VEHICLE STARTED MAKING AN AWFUL NOISE AND THE TRUCK INSTANTLY STARTED WORKING ROUGH. I PULLED OVER AND TURNED OFF THE TRUCK. MY HUSBAND CAME TO CHECK ON ME AND WHEN WE POPPED THE HOOD AND WHEN I TURNED ON THE TRUCK HE SAW THE SPARK PLUG COMING OUT OF THE CYLINDER. I HAVE YET TO HAVE THE MECHANIC LOOK AT IT. AFTER READING UP ON THIS, I SEE THIS IS A RECURRENT PROBLEM ON FORD TRUCKS. I DO NOT UNDERSTAND WHY NOTHING HAS BEEN DONE REGARDING THIS MATTER. I SIMPLY DO NOT HAVE THE FUNDS AVAILABLE TO PAY FOR THIS IF IT IS A MAJOR REPAIR JOB NOR DO I HAVE THE MEANS TO PURCHASE ANOTHER VEHICLE DUE TO THE CURRENT ECONOMIC STATE AND WERE BARELY GETTING BY AS IT IS. I WANT SOMETHING TO...

TRUCK WITH 56,000 ORIGINAL MILES. AFTER STOPPING TRUCK TO DISPOSE OF TRASH, SPARK PLUG #8 BLEW OUT OF THE ENGINE HEAD WHILE IDLING. TRUCK IMMEDIATELY TOWED TO FORD DEALERSHIP. DEALER STATED THIS IS VERY UNCOMMON PROBLEM. HELICOILED HEAD. INSTALLED NEW PLUG. $700.00. WHEN VEHICLE WAS PICKED UP FROM DEALERSHIP THERE WAS A LOUD KNOCK IN ENGINE, BUT WE WERE TOLD IT WAS WITHIN SPECS AND SAFE TO DRIVE. MECHANIC NOW SAYS THERE IS A SEVERE ROD PROBLEM, MOST LIKELY CAUSED BY PARTS OF DEBRIS IMPACTING PISTON AND CYLINDER HEAD. ESTIMATED COST $4,500. FOR REBUILT ENGINE. *TR

FAULTY SPARK PLUG COIL, STRIPS OUT OF MOTOR HEAD AND POPS OUT SPARK PLUG AND COILS. LEAVING FUMES AND GAS TO IGNITE IF DRIVEN, OR OWNER STRANDED. HAS HAPPENED 2X TO OUR FAMILY AND AFTER READING MANY FORUMS AND COMPLAINTS AND TALKING TO OTHER FORD TRUCK OWNERS IT IS A COMMON OCCURRENCE ON THESE TRUCKS. FORD SHOULD BE DOING SOMETHING ABOUT THIS. SHOULD BE A SAFETY RECALL. *TR

PROBLEM WAS INSTANT WHILE DRIVING NORTH ON RT. 18. FORD F150 V8 STARTED MISSING, SMELLING OF GAS, MAKING LOUD NOISE WHICH APPEARED TO BE EVERY TIME THE BELT WENT AROUND, UNABLE TO ACCELERATE, HAD TO KEEP ONE FOOT ON GAS AND ONE FOOT ON BRAKE AT RED LIGHT. PROBLEM WAS THAT THE SPARK PLUG OVERHEATED AND EJECTED. SAFETY ISSUE WITH FUEL VAPORS COMING OUT OF SPARK PLUG HOLE AND COULD IGNITE FROM LOOSE SPARK PLUG. FORD DENIES THIS IS A PROBLEM AND CLAIM THERE HAS ONLY BEEN THREE REPORTED CASES WHEN I HAD THE DEALER CALL THEM. AFTER TALKING ABOUT IT AT WORK, I FOUND ANOTHER EMPLOYEE THAT HAD THE SAME PROBLEM. SO THERE ARE TWO CASES RIGHT THERE THAT THEY DIDN'T EVEN KNOW ABOUT. HOW MANY CASES DO THEY REALLY KNOW ABOUT OR DENY KNOWING ABOUT? *TR

WHILE DRIVING ON THE FREEWAY, I HEARD A LOUD POP FROM THE ENGINE COMPARTMENT FOLLOWED BY THE ENGINE RUNNING ROUGHLY AND ACCOMPANIED BY POPPING SOUNDS. WITHIN 10 SECONDS, THE SMELL OF GASOLINE WAS NOTICED. I PULLED OFF AT THE NEXT EXIT, APPROXIMATELY 30 SECONDS LATER, AND CAME TO A STOP. AS I CAME TO A STOP, FLAMES ERUPTED FROM THE HOOD AND THE ENTIRE ENGINE COMPARTMENT WAS ENGULFED IN FLAMES. A FIRE TRUCK ARRIVED WITHIN A FEW MINUTES AND EXTINGUISHED THE FIRE, BUT NOT BEFORE THE FIRE HAD BURNED THROUGH THE FIREWALL INTO THE PASSENGER COMPARTMENT. THE VEHICLE WAS A TOTAL LOSS. UPON FURTHER INSPECTION, IT WAS DISCOVERED THAT THE #8 CYLINDER SPARK PLUG HAD EJECTED FROM THE CYLINDER (THE INITIAL POP SOUND) WITH SUCH FORCE THAT IT RUPTURED THE RUBBER FUEL LINE IMMEDIATELY ABOVE IT AND AFT OF THE STAINLESS FUEL INJECTOR BAR. WITH FUEL SPRAYING FROM THE HOSE,...

MY 2001 FORD F-150 TRUCK HAD ONE OF THE SPARKPLUGS EJECT FROM THE CYLINDER HEAD. THE VEHICLE HAS APPROXIMATELY 118,000 MILES. MY CONCERN IS THAT THIS COULD HAVE IGNITED INTO A FIRE SINCE GAS FUMES ARE COMING OUT OF THE SPARKPLUG OPENING. *TR

SPARK PLUG BLOWN OUT OF ENGINE AND STRIPPED THREADS IN ENGINE HEAD. DUE TO POOR ENGINEERING OF ORIGINAL THREAD LENGTH.

MY WIFE AND I WERE DRIVING TO FLORIDA FROM NORTH CAROLINA. I HAVE A 2001 FORD F150 5.4 TRITON. A LOUD POP, AND THE SPARK PLUG BLEW OUT OF THE HEAD, TAKING THE COIL WITH IT. VERY EXPENSIVE REPAIR.

I HAVE A 2001 FORD F-150 XLT 4.6L WITH 151,000 MILES. A FEW DAYS AGO, I WAS DRIVING ON INTERSTATE 64 AND HEARD A LOUD POP FROM THE ENGINE AREA. THE ENGINE STARTED TO MISS VIOLENTLY. I PULLED TO THE SIDE OF THE ROAD, RAISED THE HOOD AND NOTICED THE SPARK PLUG HAD BLOWN OUT. OF COURSE, I COULD NOT DRIVE THE TRUCK ANYWHERE SO MY 10 YEAR OLD SON AND I HAD TO WAIT FOR AN HOUR FOR A TOW TRUCK. AFTER SOME RESEARCH, I REALIZE THAT THIS HAS HAPPENED TO THOUSANDS OF PEOPLE. FORD SEEMS TO BLAME INCORRECT TORQUING OF THE SPARK PLUGS, BUT MOST PEOPLE BLAME A POOR DESIGN IN THE SMALL QUANTITY OF THREADS HOLDING THE SPARK PLUG. I CAN SAY THAT NO ONE HAS TOUCHED THE PLUGS IN THIS TRUCK EXCEPT FOR A FORD DEALERSHIP WHEN THE PLUGS WERE CHANGED AT 75,000 MILES. I AM...

I HAVE A FORD F-150 2001 WITH TRITON 5.4 V8 I STARTED MY TRUCK AND HEARD A LOUD POP AND THEN WHAT SOUNDED LIKE A VERY BAD EXHAUST LEAK. COME TO FIND OUT THE BACK SPARKPLUG ON PASSENGER SIDE BLEW OUT. I HAD TO HAVE A NEW COIL NEW PLUG AND HELICOIL INSTALLED. *TR

2001 FORD F150 SPARK PLUG BLOWOUT HAS LEFT ME WITHOUT A VEHICLE AND OUT OF MONEY NOW. ACCORDING TO MY RESEARCH THIS IS A COMMON PROBLEM AMONG ALL FORD V8'S AND V10'S FROM 1999 TO 2002. THE PROBLEM IS DUE TO LACK OF THREADS IN THE ALUMINUM HEADS (ONLY FOUR THEADS), AND HAS RESULTED IN SEVERAL FIRES AND EXTENSIVE PROPERTY DAMAGE. APPARENTLY ALL ATTEMPTS AT A RECALL AND CLASS ACTION LAW SUIT HAVE BEEN MET WITH RELATIVE DISREGARD. DESPITE THE FACT THAT FORD REDESIGNED THEIR HEADS AFTER 2002 TO CORRECT THIS PROBLEM THEY STILL REFUSE ANY ASSISTANCE TO CUSTOMERS WHO SUFFER DUE TO THEIR DESIGN FLAW. APPARENTLY SOMEONE WILL HAVE TO DIE FROM THE ENGINE FIRE BEFORE ANYTHING WILL BE DONE. AND EVENTUALLY SOMEONE WILL DIE, IF THEY HAVEN'T ALREADY. PERHAPS A DEATH DUE TO THIS PROBLEM MIGHT FORCE LEGAL ACTION. I'M CURRENTLY LOOKING AT OVER $3000 WORTH OF REPAIR...

I WAS DRIVING ON INTERSTATE 5 WHEN THERE WAS A LOUD POP FOLLOWED BY RAPID POPPING FROM THE ENGINE. AT FIRST I THOUGHT IT MIGHT BE A FLAT AND PULLED ONTO THE SHOULDER, BUT THE NOISE CONTINUED EVEN THOUGH I WAS STOPPED. I OPENED THE HOOD AND AT FIRST (BASED ON THE SOUND) THOUGHT IT MIGHT BE THE EXHAUST MANIFOLD. I WAS TOWED TO THE NEAREST FORD DEALER WHERE THE PROBLEM WAS DETERMINED TO BE A BLOWN SPARK PLUG WHICH HAD STRIPPED THE PLUG'S THREADS. THE DEALER INSERTED A HELI-COIL AND AFTER A TOW, AN OVERNIGHT STAY AT A NEARBY MOTEL, 5 HOURS OF WAITING THE NEXT DAY AND $415 IN REPAIRS I WAS BACK ON THE ROAD. I HAVE SINCE DONE SOME INTERNET SEARCHING AND HAVE COME TO FIND THAT THIS IS A VERY COMMON OCCURRENCE WITH THE TRITON ENGINE AND HAS BEEN SO FOR SEVERAL YEARS DUE TO...

DURING NORMAL DRIVING THE SPARK PLUG IN CYLINDER #3 BLEW OUT OF THE CYLINDER. THIS DISABLES THE VEHICLE. SPARK PLUG EJECTION IS DANGEROUS BECAUSE FUEL VAPOR STARTS COMING OUT THE SPARK PLUG HOLE, WHICH IS CLEARLY A SERIOUS SAFETY ISSUE. THE FUEL VAPOR CAN BE IGNITED BY THE EJECTED SPARK PLUG. THE SPARK PLUG WAS THE ORIGINAL INSTALLED IN THE ENGINE FROM THE FACTORY. THE BLOW OUT DAMAGES THE SPARK PLUG HOLE THREADS AND IT ALSO DAMAGED THE COIL PACK. REPAIR IS VERY EXPENSIVE AND REQUIRES A TECHNICIAN TO TAP A NEW HOLE AND PLACE A THREADED INSERT IN IT. THE PROBLEM IS THESE TYPE OF REPAIRS ARE NOT USUALLY RELIABLE. *TR
