My 2001 Ford F-150 truck had a spark plug eject from the cylinder and hit the fuel rail while on the highway on 9-1-06 (70,000 miles on odometer). I had the truck hauled to nearest service center where they fixed the cylinder with a repair kit made for this problem. On 2-26-07 at 79 thousand miles another plug ejected with the same consequence. Now the entire head has to be replaced at a cost of $3600 to me.
Blown out spark plug on passenger side of 2001 f 150 with 102k miles.
The consumer was unable to start the vehicle. The dealership repaired the lock cylinder.
Water gatting to the spark plug cavity from small puddle causing fouling.
I was driving down the highway and all of a sudden the engine starts to make a popping sound. I pulled over and raised the hood. The #3 spark plug had blown out from its seating in the cylinder head. I had the truck towed to the dealer and they replaced the cylinder head. This is a known problem and could be very dangerous because of the location of the fuel injection rail. The sparkplug is located directly below the fuel rail. If the spark plug comes loose and it flies into the fuel rail, the rail could burst causing fuel to spray inside the engine compartment igniting a fire. The spark plug problem was taken care of by Ford, however nothing was done to guard the fuel rail.
