IllustrationWHILE DRIVING 25 MPH THE #2 SPARK PLUG STRIPED ITS THREADS AND BLEW OUT OF THE HEAD. THE PLUG REMAINED IN THE WIRING HARNESS CAP AND CONTINUED TO SPARK. THE REPAIR COST $220.00. I AM TOLD THIS IS AN ONGOING DEFECT IN THE DESIGN OF SOME OF FORDS ENGINES. *TR

SPARK PLUG BLEW OUT OF THE HEAD WITH SUCH FORCE THAT IT CRACKED THE COIL AND WAS SPARKING ON THE FUEL LINE WITH FUEL VAPORS COMING OUT OF THE HEAD AT THE SAME TIME. THIS COULD HAVE CAUSED A FIRE/EXPLOSION IF THE VEHICLE COULD NOT HAVE BEEN SHUT OFF QUICKLY ENOUGH. I WAS IDLE IN MY DRIVEWAY AND NOT ON THE HIGHWAY WHERE IT WOULD HAVE TAKEN LONGER TO SHUT THE VEHICLE OFF. INTERNET RESEARCH RETURNED ASTONISHING AMOUNT OF COMPLAINTS FOR THE SAME ISSUE. *TR

I HAVE A 1998 FORD PICKUP WITH A 5.4L ENGINE AND JUST TODAY AS I WAS DRIVING IT THE SPARK PLUG BLEW OUT. AS SOON AS I HEARD THE POPPING SOUND I IMMEDIATELY SHUT THE TRUCK DOWN. I OPENED THE HOOD AND THERE WAS THE PLUG DANGLING THERE. I WAS ABLE TO INSTALL THE PLUG BACK ON BUT GOT 3 TURNS ON IT AND IT WAS TIGHT. NO WAY SHOULD A SPARK PLUG ONLY HAVE A FEW TURNS ON IT AND NO WAY SHOULD A PLUG FLY OUT OF AN ENGINE THAT IS SPEWING GASOLINE AND THE PLUG STILL SPARKING. IF THERE IS A CLASS ACTION LAWSUIT AGAINST THIS COMPANY SIGN ME UP. NEVER AGAIN WILL I BUY A FORD PRODUCT. ALL THEIR VEHICLES CATCH FIRE( REMEMBER THE CRUISE CONTROL). THIS IS A PRIME EXAMPLE WHY THE US AUTO INDUSTRY SUCKS AND THEY STILL WANT US TO BAIL THEM OUT. I HAVE HALF A MIND TO GO TO DETROIT AND BEAT THE CRAP OUT OF AN ENGINEER THERE. I AM ALL FOR AN ATTORNEY TO CALL ME IF IT IS A CLASS ACTION LAWSUIT. IF YOU MAKE FAULTY DANGEROUS PRODUCTS SUCH AS THIS YOU SHOULD BE PUT IN JAIL! PEOPLE CAN DIE FROM THIS! I HOPE FORD GOES THE WAY OF ALL THE REST OF THE OLD AMERICAN AUTO MAKERS. WE SHOULD NOT HAVE TO BAIL THEM OUT SO THEY CAN MAKE MORE DANGEROUS PRODUCTS AND SNOWBALL THE PUBLIC!! *TR
I WAS TOWING AN ULTRA LIGHT CAMPING TRAILER WITH THE CRUISE CONTROL ENGAGED WHEN I SMELLED WHAT APPEARED TO BE AN ELECTRICAL FIRE THEN THE ENGINE IMMEDIATELY FAILED . I REPLACED THE ENTIRE ENGINE AT A COST OF $ 4000.00 AND HAVE HAD AT LEAST 10 MORE INSTANCES WHERE THE CRUISE CONTROL STOPPED WORKING ON THE INTERSTATE. *JB
I WAS DRIVING AN HEARD A LOUD SQUEALING NOISE FROM UNDER THE HOOD. LOST POWER AND LIGHTS DIMMED FOR A BRIEF PERIOD. I PULLED OVER AND SMELLED ANTIFREEZE BEFORE I OPENED THE HOOD.

I WAS DRIVING AN HEARD A LOUD SQUEALING NOISE FROM UNDER THE HOOD. LOST POWER AND LIGHTS DIMMED FOR A BRIEF PERIOD. I PULLED OVER AND SMELLED ANTIFREEZE BEFORE I OPENED THE HOOD. I CHECKED THE COOLANT RECOVERY TANK LEVEL AND IT WAS SLIGHTLY LOW. LOOKED FOR A LEAK AND FOUND A 1/16TH" PINHOLE APPROXIMATELY ONE INCH BELOW THE THERMOSTAT HOUSING GASKET LINE PRODUCING A STEADY STREAM OF ANTIFREEZE DIRECTLY ONTO THE SERPENTINE BELT. THIS STRONG LEAK CONTINUES AS LONG AS THE PROPER FLUID LEVEL IS MAINTAINED, AND STOPS ONCE THE LEVEL FALLS BELOW THE HOLE. TO REFILL THE TANK TO IT'S PROPER LEVEL TAKES APPROXIMATELY ONE US GALLON OF COOLANT, WHICH IMMEDIATELY BEGINS TO SQUIRT OUT THE HOLE, WHETHER THE ENGINE IS RUNNING OR NOT; HOT OR COLD. TOOK IT TO MY MECHANIC WHO TOLD ME ALL HE COULD DO IS REPLACE THE ENGINE, WHICH I HAVE NOT DONE. I WILL BE TAKING IT TO THE CLOSEST FORD DEALER, AS SEVERAL OTHER PROFESSIONAL MECHANICS HAVE LOOKED AT IT AND ALL AGREED THAT IT WAS A DEFECT IN THE CASTING, SINCE THERE WAS NO CRACKING- JUST A ROUND PIN HOLE IN AN AREA WHERE THERE ARE NO MOVING PARTS THAT COULD HAVE CAUSED SUCH DAMAGE.*AK
I OWN A 1998 FORD F150 XLT TRUCK. I MAINTAIN MY TRUCK AS REQUIRED (OIL, ETC). ON OCT. 25,2003 WHEN GOING TO TURN THE TRUCK ON I HEARD A LOUD NOISE IN THE ENGINE AND THE TRUCK SEEM TO STALL.

I OWN A 1998 FORD F150 XLT TRUCK. I MAINTAIN MY TRUCK AS REQUIRED (OIL, ETC). ON OCT. 25,2003 WHEN GOING TO TURN THE TRUCK ON I HEARD A LOUD NOISE IN THE ENGINE AND THE TRUCK SEEM TO STALL. I LOOKED UNDER THE TRUCK AND NOTICED A HOLE ON THE RIGHT SIDE OF THE OIL PAN PANEL AND OIL CAME OUT. ONCE I GOT IT TO TALK TO MY MECHANIC HE INFORMED ME THAT HE KNEW OF THE 'NOTORIUS' OR 'INFAMOUS' REPUTATION THE (4.2L FORD ENGINES) HAVE. IT SEEMS DISTURBING TO ME THAT FORD WOULD USE ENGINES LIKE THIS ON VEICHLES AND US CONSUMERS SPENDING ARE HARD EARNED MONEY HAVE TO PAY FOR SOMETHING THAT NO MATTER HOW GOOD YOU MAINTAIN WILL EVENTUALLY BREAK DOWN. I CAME TO FIND OUT THAT PEOPLE THAT ARE INVOLVED WITH CARS (MECHANICS AND MANAGERS OF WELL KNOWN PART STORES) CALL THIS TYPE OF MOTOR ENGINE. NOW I NEED TO PUT A NEW ENGINE INTO A TRUCK THAT OTHERWISE RAN FINE. I WILL NEVER EVER BUY A FORD AGAIN AND WARN ALL MY CLOSE FRIENDS AND COLLEAGUES TO DO THE SAME.
I CURRENTLY HAVE A 1998 FORD F150 4.2L ENGINE THAT HAS 65000 MILES AND AM EXPERIENCING HEAD GASKET FAILURE. FORD MOCO STATS THERE IS NO TSP'S OR RECALLS REGUARDING THIS. I PULLED THE OWNERS NOTIFICATION 98B33 OFF YOUR WEB SITE. MY ENGINE BUILD DATE IS NOV 1997 AT THE ESSEX PLANT. I AM IN THE ARMY AND AM STATIONED IN GERMANY…

I CURRENTLY HAVE A 1998 FORD F150 4.2L ENGINE THAT HAS 65000 MILES AND AM EXPERIENCING HEAD GASKET FAILURE. FORD MOCO STATS THERE IS NO TSP'S OR RECALLS REGUARDING THIS. I PULLED THE OWNERS NOTIFICATION 98B33 OFF YOUR WEB SITE. MY ENGINE BUILD DATE IS NOV 1997 AT THE ESSEX PLANT. I AM IN THE ARMY AND AM STATIONED IN GERMANY. THE DEALERSHIP HERE QUOTED ME 2500.00 FOR THE ESTIMATE. AT THIS TIME THEY WILL NOT HONOR THE U.S. ESP PURCHASED FROM THE ORIGINAL DEALER. I AM CURRENTLY TRYING TO GET THIS RESOLVED. FORD WILL NOT GIVE PART TO ME AT NO COST TO FIX THERE DEFECTIVE HEAD GASKETS AND LOWER INTAKE MANIDOLS GASKETS AND ENGINE FRONT COVER GASKETS. THEY ARE GIVING ME THE RUN AROUND AND CAN'T GET ME STRAIGHT ANSWERS. I AM CONTINUING WORKING WITH MY DEALERSHIP. I AM AFRAID THEY WILL SIT ON THIS UNTIL MY WARRANTY RUNS OUT ON THE 22 JANUARY 2003.
