IllustrationI'VE HAD TWO PLUGS BLOW OUT ON MY 99 F150. IT HAS LESS THAN 100,000 ON IT. IF THEY KNOW ITS A DEFECT WHY NOT STEP UP AND FIX THE PROBLEM? IT COST $300 A PLUG!!!! LEFT ME STRANDED AT NIGHT WITH MY FAMILY ALONG THE ROAD!! MAKES ME WONDER IF I WANT TO STAY WITH FORD OR GO ELSEWHERE. *TR

I HAD JUST GOT OFF WORK AND WAS LEAVING THE PARKING AREA AND BLEW OUT THE NUMBER 4 SPARKPLUG ON THE RIGHT SIDE HEAD. I SHUT OFF THE MY TRUCK AND PARKED IT. I CALLED A FRIEND THAT LIVES CLOSE FOR A RIDE HOME. THE NEXT MORNING I DROVE BACK TO THE PLANT AND TOOK MY TRUCK TO THE LOCAL FORD DEALERSHIP. THEY SAID THAT I SHOULD REPLACE THE HEAD OR INSTALL A HELICOIL AND ALSO REPLACE THE SPARK PLUG AND COIL PACK. SO I HAD THEM INSTALL THE HELICOIL AND REPLACE THE DAMAGED PARTS. LESS THEN A MONTH LATER I WAS DRIVING TO WORK ON THE I 90 AND I BLOW OUT THE NUMBER 5 CYLINDER SPARK PLUG AND THIS TIME IT TOOK OUT THE PLASTIC SHIELD AND RIPPED THE SPARK PLUG AND THE COIL PACK OFF HE TRUCK. I HAVE NOT DONE ANY THING BUT CONTACT FORD MOTOR COMPANY ABOUT THIS AT THIS TIME. THERE SUGGESTION WAS TO REPLACE THE HEADS MY SELF AT A COST OF 6,000 DOLLARS. *TR

I WAS DRIVING MY 1999 FORD F150 4X4 WITH 5.4L ENGINE HOME FROM WORK AND STOPPED AT TRAFFIC LIGHT. THE LIGHT TURNED GREEN AND I PROCEEDED TO GO AND THEN "POW" THE TRUCK BEGAN TO MAKE A LOUD "POPPING" NOISE AND LOST ALL ENGINE POWER. I WAS IN THE MIDDLE OF THE INTERSECTION AND SOMEHOW MANAGED TO KEEP IT RUNNING LONG ENOUGH TO GET THROUGH THE INTERSECTION AND ON A SIDE ROAD. I HESITATED TO OPEN THE HOOD BECAUSE OF THE STRONG GASOLINE SMELL BUT IT WASN'T ON FIRE "YET" SO I OPENED IT AND FOUND ONE OF MY IGNITION COILS (COIL PACKS) LOOSE ON TOP OF THE INTAKE MANIFOLD. UPON FURTHER INSPECTION I REALIZED THE SPARK PLUG HAD BLOWN OUT OF THE ALUMINUM CYLINDER HEAD. I WAS ABLE TO CATCH A RIDE TO THE AUTO PARTS STORE WITH COIL AND PLUG IN HAND. THE SALESMAN AT THE STORE IMMEDIATELY KNEW WHAT HAD HAPPENED AND EVEN KNEW THE ENGINE WAS A 5.4L BEFORE BEING TOLD. HE SAID THAT IF I WAS LUCKY I WOULD PROBABLY JUST HAVE TO INSTALL A HELICOIL OR THREADED INSERT IN IT. THE OTHER OPTION WAS TO REPLACE THE CYLINDER HEAD. I PURCHASED NEW COIL AND PLUG THEN DROVE BACK TO MY TRUCK. I TRIED TO CLEAN THE THREADS WITH A SPARK PLUG THREAD CHASER BUT THERE WERE NO THREADS LEFT TO CLEAN. I SEARCHED THE WEB AND FOUND NUMEROUS COMPLAINTS OF THE SAME ISSUE. SOME PEOPLE SAID THEY HAD MULTIPLE SPARK PLUGS BLOW OUT OR "SPIT OUT" ON THE SAME VEHICLE. WHY DOESN'T FORD HAVE A RECALL ON THIS? THE GASOLINE SMELL WAS DUE TO THE FUEL INJECTOR STILL SPRAYING WHILE THE PLUG WAS BLOWN OUT OF THE HEAD. WHAT IF IT HAD CAUGHT ON FIRE? I HAVEN'T REPAIRED IT YET BUT WILL TRY THE "REPAIR KIT" THAT WAS HANDED TO ME WHEN I BOUGHT THE COIL AND PLUG. I THINK FORD SHOULD RECALL ALL THE 5.4L ENGINES THAT HAVE THIS PROBLEM AND INSTALL THE HELICOIL OR INSERT TO PREVENT A CUSTOMER BREAKDOWN OR A POTENTIAL VEHICLE FIRE. *TR
BLEW OUT SPARKPLUGS AND BROKE BRACKET ON THE SIDE OF COIL PACKS. DON'T LIKE PAYING $85 A POP FOR FORD'S POOR DESIGN. PLUS THE HEALY COILS OR MAYBE THAT'S THE MOTIVE. THIS HAPPENED THREE DIFFERENT TIMES. *TR
MY FAMILY AND I WERE 25 MILES FROM HOME IN OUR 1999 FORD F-250 WHEN A SPARK PLUG BLEW OUT OF THE HEAD. I HAD THE TRUCK TOWED TO THE FORD DEALERSHIP AND WAS TOLD THAT EVEN THOUGH THE TRUCK HAD LESS THAN 75,000 MILES. I HAD TO PAY FOR THE REPAIR. THIS REPAIR COST US OVER $3,000. *JB
1999 FORD EXPEDITION FIRST BLEW OUT A SPARK PLUG IN 2003 DUE TO TOO FEW THREADS IN CYLINDER HEAD. MECHANIC WAS ABLE TO REPAIR FOR AROUND $500. THE PROBLEM OCCURRED AGAIN ON ANOTHER SPARK PLUG IN 2004 WHICH DESTROYED THE WHOLE ENGINE. I CONTACTED FORD AND WAS TOLD THEY COULD DO NOTHING ABOUT IT. THE REFURBISHED JASPER ENGINE ENDE…

1999 FORD EXPEDITION FIRST BLEW OUT A SPARK PLUG IN 2003 DUE TO TOO FEW THREADS IN CYLINDER HEAD. MECHANIC WAS ABLE TO REPAIR FOR AROUND $500. THE PROBLEM OCCURRED AGAIN ON ANOTHER SPARK PLUG IN 2004 WHICH DESTROYED THE WHOLE ENGINE. I CONTACTED FORD AND WAS TOLD THEY COULD DO NOTHING ABOUT IT. THE REFURBISHED JASPER ENGINE ENDED UP BEING AROUND $5400. THE OLD ENGINE WAS TURNED IN TO AVOID A CORE CHARGE. I HAVE ALL OF THE PAPERWORK FROM THE MECHANIC STATING THE PROBLEM. *NM
I BLEW A PLUG ON MY FORD F150. ENGINE HAS HAD PROPER MAINTENANCE. IT HAS ABOUT 80,000 MILES ON IT. 5.4 V8 YEAR IS 1999. CALLED FORD AND THEY WILL NO ACKNOWLEDGE A PROBLEM AND WILL DO NOTHING TO REIMBURSE ANY OF THE REPAIR COSTS. I THINK IT IS A FAULTY HEAD ON THE TRITON ENGINES.

ON THE DAY LISTED BELOW MY 1999 FORD F150 WITH A TRITON 5.4L V8 ENGINE EJECTED A SPARK PLUG FROM THE CYLINDER HEAD. UPON INSPECTION BY A MECHANIC IT WAS DETERMINED THAT THE THREADS IN THE CYLINDER HEAD FAILED. THE COMPRESSION IN THE CYLINDER THEN EJECTED THE SPARK PLUG. AFTER THE SPARK PLUG WAS EJECTED AND BEFORE I COULD GET STOPPED THERE WAS A STRONG SMELL OF GAS IN THE CAB OF THE TRUCK. WHICH I ASSUME WAS CAUSED BY THE OPEN CYLINDER AND FUEL BEING EXPRESSED THROUGH THE SPARK PLUG OPENING. *AK

6.8 LITRE V-10 ENGINE AND ONE SPARK PLUG FROM EACH CYLINDER HEAD CAME OUT. ONE CYL HEAD HAD THREADS DESTOYED THEREBY MAKING A REPLACEMENT NESSESARY AND THE OTHER ONE WAS SUSPECT. THE DEALER SUGGESTED A REBUILT ENGINE AS COSTS WOULD BE VERY CLOSE BETWEEN REPAIRS AND A GENUINE FORD REBUILT ENGINE AND IT WOULD COME WITH A WARRENTY. MY COMPLAINT IS THAT THE PLUGS CAME OUT BECAUSE THE CYL HEADS WERE A POOR DESIGN WITH ONLY 3/8" THREADS IN AN ALUMINUM CASTING AND I SHOULDN'T BE PAYING FOR POOR ENGINEERING AND DESIGNS. THERE HAS BEEN AN UPDATE IN 2001 THAT NOW HAS A CYL HEAD WITH 9/16" THREADS AND PLUGS TO SUIT. I WANT FORD TO INSTALL A NEW UPDATED ENGINE AT THEIR COST.
