1999 FORD F SERIES Engine And Engine Cooling Problems

I'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...

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

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

1999 F-150 HEAD GASKET LEAKING ON RIGHT BACK SIDE ON EXHAUST AND CATALYTIC CONVERT SMELL AND SEE SMOKE AFFRAID OF FIRE WHILE DRIVING OR PARKED .*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.
