There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

    front plug on the passenger side of the engine. Fixed by the guys at blownoutsparkplug.com. They did a great job and are very knowleagable of this problem. They changed all the spark plugs with new ones and checked all the other cylinders for potential problems. Have not had any problems since.

    Started my vehicle today, 12/15/2012, at the mall and..boom!! then some smell of smoke inside the vehicle ...then more popping which sounded almost like a belt slapping against something under the hood. I had no prior indication of a problem except yesterday morning there was a vibration in the steering wheel while accelerating that stopped once letting off the gas. It did smooth out within 45-60 seconds and did not reoccur. Then today's issue occurred. I had the truck, F-250, 2003 Quad Cab, with 150-K miles towed to the Ford dealership about a mile away which was the place of original purchase. Initial estimate to repair it..$700.00; not a happy christmas gift

    #5 blew out, it also destroyed the ignition coil
    The best repair is to remove both heads and have a machine shop install new inserts
    I have heard (but not seen) that some of the inserts installed with the engine still assembled have failed, this is most likely due to lack of room and access in the engine compartment
