2007 Ford F-150

THE THREADS IN MY 07 FORD F 150 FOR MY SPARK PLUG IN ONE OF MY CYLINDER'S WENT BAD. AND MY PLUG LEAKED HIGH PRESSURE COMPRESSED HEATED EXHAUST. CAUSING MY IGNITION COIL TO PARTIALLY MELT. ITS RIGHT BELOW THE FUEL RAIL SENSOR TOO. ITS THE BIGGEST PAIN IN THE BUTT TO FIX. USED A HELICOIL. DIDN'T LAST TOO LONG. TRYING A MORE PERMANENT FIX NEXT. I WAS ON THE HIGHWAY GOING 70 WHEN THE PLUG BEGAN A VERY NOTICEABLY LOUD RHYTHMIC LEAK WITH THE IGNITION OF THAT CYLINDER. ALSO, WHEN I SAW THE PROBLEM WHEN I LOOKED AT THE SPARK PLUG. IT HAD ALREADY HAD AN EXISTING HELICOIL PUT IN. AND YOU COULD TELL THIS HAPPEND WAY BEFORE 200K MILES. BECAUSE THE OLD SPARK PLUG WAS WORN ALMOST ALL THE WAY DOWN. I STILL HAVE THE OLD SPARK PLUG.

IN APRIL 2015 I BEGAN EXPERIENCING ENGINE KNOCKING ON MY 2007 FORD F-150 WHICH HAD 57,532 MILES ON IT. I TOOK IT TO FORD SERVICE DEPARTMENT AND ENDED UP SPENDING $3,080.79 TO REPLACE CAMSHAFT, SOLENOID, AND TIMING CHAINS. I WAS TOLD THIS WORK WAS GUARANTEED. NOW, LESS THAN 7 MONTHS LATER AT 61,452 MILES I BEGAN HEARING SQUEAKING AS I DRIVE. TOOK IT BACK TO FORD AND THEY TELL ME IT IS NOW THE HARMONIC BALANCER IS OUT AND EXCESSIVE CRANK SHAFT END PLAY. I AM TOLD THAT THE ISSUE IS NOT RELATED TO THE PRIOR REPAIR WORK SO I WILL HAVE TO SPEND ANOTHER $3,000 OR MORE TO FIX THIS ISSUE. THIS IS ALL AFTER I SPENT OVER $300 IN DECEMBER 2014 TO REPLACE THE INGNITION COILS. I DRIVE MOSTLY CITY DRIVING. WE PICKED UP VEHICLE WITHOUT REPAIRING IT THIS TIME SO WE COULD FIGURE OUT WHAT TO DO.

VEHICLE HAS STARTED TO JERK AROUND 40-50 MPH. REVIEWS STATES THE SPARK PLUGS AND COILS ARE THE ISSUES. WANTED TO CHANGE OUT SPARK PLUGS, BUT UNDERSTAND THE PLUGS BREAKS UPON REMOVAL AND VERY EXPENSIVE TO FIX. KNOW ISSUE BY FORD MOTOR COMPANY. NOW I DON'T EVEN WANT TO ATTEMPT CHANGING OUT THE PLUGS. THIS ISSUE SHOULD BE RECALL OR PAID BY FORD FOR REPLACEMENT, SINCE THIS ISSUE IS KNOW BY FORD. ISSUE IS STILL ONGOING, HELP, DON'T WANT TO PAY $1000 FOR A SIMPLY MAINTENANCE.

THE FAILURES STEM FROM BAD OIL FLOW TO THE TOP END OF THE ENGINE DUE TO A FLAW IN DESIGN. SPECIFICALLY MY CAMSHAFT, CAM PHASER, TIMING COMPONENTS AND LIFTERS ROLLERS HAVE FAILED. THE PROBLEM FIRST SHOWED UP AT 42256 MILES AND HAS SINCE RESURFACED TWICE EVEN AFTER EXPENSIVE REPAIRS. THE WORRISOME PART IS THAT THE WEB IS FILLED WITH THOUSANDS UPON THOUSANDS OF SIMILAR COMPLAINTS ABOUT THIS ENGINE WHICH IS ALSO IN EXPEDITIONS AND CROWN VICTORIAS AND PROBABLY OTHER FORD VEHICLES.

BOUGHT THE T07 F150 AT 28K AND AT 61K THIS HAPPENED. WHILE DRIVING AT LOW GEAR 2ND THE ENGING CHUGGED A LITTLE ( LKE AN OLD DIESAL) TOOK IT TO THE DEALER THEY SAID IT WAS PROBABLY THE SMALL OIL SEAL BEHIND THE CAM. THEY WAS GOING TO CHARGE BE 5600 FOR A NEW ENGINE. THEY TRIED LIKE HE11 TO GET ME TO SAY I DIDNT HAVE THE OIL CHANGED REGULARLY. I NEVER BACKED DOWN, THEN REMINDED THEM THAT I HAD BOUGHT THE $2700.00 EXTENDED WARRENTY (WHICH I USUALLY NEVER DID) THEY BAUKED AND CRIED. BUY SAID THAT THEY WOULD FIND ANOTHER USED ENGINE, THEY CALLED ME AND SAID THAT THEY FOUND ONE FOR 3500 (OR SOMETHING LIKE THAT) I BEGAN A LONG SEARCH ONLINE AND FOUND A REBUILD FOR LESS AND GAVE THEM THE INFORMATION. THEY DECIDED TO GO WITH THAT. THEY ORDERED THE ENGINE AND INSTALLED IT ( WELL WHAT DO YOU KNOW THE REPLACEMENT HAD THE SAME PROB) THEY HAD TO PULL THAT ENGINE AND GET ANOTHER FROM THE COMPANY . TOOK AN EXTRA WEEK AND GOT THE TRUCK BACK ITS NOW AT 100K AND STILL RUNS WELL (SO I KNOW IT WASNT MY DRIVING) SO IT HAD TO BE THE INCORRECT PLACEMENT OF THAT SEAL FROM THE DEALER, WHICH WOULD LEAKED HOT OIL ONTO THE ENGINE AND CAUSE A FIRE. I LOOKED AT THE ORIGIONAL PAPER WORK THAT THEY HAD TO REPLACE TH ORIGIONAL WIRING HARNESS BEFORE IT EVEN LEFT THE FACTORY.

THE ENGINE WAS REPLACED IN 2012 WITH 53,000 MILES ON THE TRUCK DUE TO A SIGNIFICANT KNOCKING COMING FROM THE ENGINE. THE TRUCK WAS STILL UNDER WARRANTY SO IT COST ME NOTHING TO REPLACE. THE ENGINE STARTED TO MAKE THE SAME SOUND IN FEB 2015 (84,000 MILES ON THE TRUCK, 30,000 MILES ON THE ENGINE). I HAD IT TAKEN TO AN AUTO MECH AND THEY TOLD ME ONE OF THE SPARK PLUGS EJECTED FROM THE ENGINE AND RIPPED ALL THE THREADING OUT. THEY ALSO FOUND THAT ON E OF THE CYLINDERS BROKE OFF THE CRANK SHAFT AND CEASED. THE ENGINE HAS TO BE REPLACED AGAIN AND THE TRUCK IS NO LONGER UNDER WARRANTY. BOTH THE ORIGINAL DEALERSHIP THAT REPLACED THE ENGINE AND THE AUTO MECH THAT I HAD THE TRUCK TAKEN TO, ARE RESEARCHING IF THE PARTS ARE STILL UNDER WARRANTY.
