2000 FORD F SUPER DUTY Engine And Engine Coolingenginegasoline Problems

SECOND SPARK PLUG IN MY 2000 FORD V10 HAS BLOWN OUT OF CYLINDER HEAD IN LAST THREE MONTHS. LAST PLUG CAME OUT TUESDAY AFTER CHRISTMAS. DEALER NOW SAYS IT NEEDS TO DO $3475 HEAD REPLACEMENT FOR BOTH HEADS. *JB

MY VEHICLE HAS BLOWN OUT A SPARK PLUG ON TWO SEPARATE OCCASIONS WHILE ON THE FREEWAY ALMOST CAUSING A ACCIDENT ON BOTH INCIDENTS. I KNOW THAT THIS IS A MAJOR PROBLEM DO TO WHAT I HAVE FOUND ON-LINE. THERE IS EVEN A COMPANY THAT MAKES A REPAIR KIT AND IT IS ONLY A MATTER OF TIME BEFORE SOMEONE IS STRANDED IN A REMOTE AREA WHICH WILL BE VERY DANGEROUS. *NM

I HAVE A 2000 F-250 WITH 62,000 MI. AND HAD ONE OF THE SPARK PLUGS BACK OUT AND STRIP OUT THE LAST FEW THREADS. I SPOKE TO A MECHANIC WHO TOLD ME THAT THE 5.4 ENGINE IS KNOWN FOR THIS AND THAT FORDS ONLY FIX TO IT WAS TO REPLACE THE HEAD AT @ $1500.00 PER HEAD. HE REFERRED ME TO ANOTHER MECHANIC THAT DEVISED A CHEAPER FIX OF RETAPPING THE PLUG HOLE. THIS MECHANIC SAID THAT HE PERSONALLY HAS DONE 5 TO INCLUDE MY TRUCK.*AK

THIS IS MY SECOND FORD TRUCK IN A YEAR 1/2 AND MY FORTH MOTOR I AM EXPERIENCING A LOUD ENGINE KNOCK ON COLD START UP. THE KNOCK GETS LOUDER AND LONGER. FORD HAS REPLACED LIFTERS ON MY 2000, THAT DID NOT TAKE CARE OF THE KNOCK. I HAVE TALKED TO DIFFERENT PEOPLE THAT OWN THE 5.4 ENGINE AND THEY EXPEREINCE THE SAME NOISE. I HAVE FOUND MOST PEOPLE DO NOT NOTICE THE NOISE BECAUSE OF THE RADIO,AS WELL AS THE BELL NOISE WHEN YOU FIRST START THE TRUCK. I HAVE ALSO HAD A SPARK PLUG EJECTED FROM THE CYLINDER HEAD OF MY 1999. THE FORD DEALER WANT TO REPLACE MY 2000 5.4 ENGINE WITH A NEW ONE . HOW MUCH SHOULD A CONSUMER TAKE. HERE I GO AGAIN WITH ENGINE REPLACEMENT IN A NEW TRUCK LESS THAN A YEAR OLD. PLEASE HELP!!!! THANK YOU!!!*AK
