Have a 2003 Ford F-250 with the 5.4L Triton engine I have owned the truck approx. 6months and in a matter of 1000 miles I have blown 2 spark plugs and inserts out, this repair has cost me $300 each time and $150 in towing fees, I am waiting to see when the other ones will blow, this problem is well known by all mechanics and make the repairs often, if this problem is so well known maybe Ford should address this issue and demand a recall of all vehicles with this well known issue, this problem also causes other issues, like engine fires due to the fuel fumes escaping from where the spark plug should be, when I try to research this problem I see that there is a website dedicated to this truck and problem so apparently Ford is waiting for an engine blowup to kill someone before they take this seriously.
