1998 FORD EXPEDITION Engine And Engine Coolingengine Problems

OUR 1998 FORD EXPEDITION WITH THE 5.4 V8 TRITON ENGINE HAD ANOTHER SPARK PLUG BLOW OUT OF THE CYLINDER HEAD. THE LAST TIME THIS HAPPENED WAS ABOUT 3 YEARS AGO, IT WAS THE #3 CYLINDER PLUG THEN AND LAST WEEK IT WAS THE #6 CYLINDER PLUG, I SEARCHED THE INTERNET CONCERNING THIS PROBLEM AND FOUND HUNDREDS IF NOT MORE OF THE SAME ISSUES, AND NO ONE IS MAKING FORD DO ANYTHING ABOUT THIS, JUST THOUGHT MY VOICE IN THIS MATTER MIGHT HELP. PLEASE IF THERE WAS EVER AN INSTANCE OF A RECALL THIS IS SURELY ONE. THIS IS GETTING VERY EXPENSIVE FOR THE AUTO OWNER, THE FIRST TIME WE HAD IT FIXED BY FORD AND IT WAS $250 AND THIS TIME IT WAS OVER $1,000. THANK YOU FOR ADDRESSING THIS ISSUE. *TR *KB
