| Description of the problem | Vehicle 2004 f150 5. 4l triton problem: you cannot service the spark plugs without breaking them off in the head. Even when using ford written tsb, spark plugs will break off leaving ground shield in cylinder head. Per ford's owners manual spark plugs should be replaced at the 100,000 mile mark. I replaced mine at 35,000 and broken one off in the cylinder head. I used the ford issued tsb to extract them and was still not successfully. This issue will only grow in magnitude as more people become aware and more vehicles start to approach the 100,000 mile mark. This issue is begin well documented at the ford dealers and ford has also acknowledged by writing a tsb for this failure mode. I ask that nhtsa get involved and force ford to design a spark plug that is capable of begin extracted at any mileage interval without the threat of them breaking off. Thank you for your time. *jb |
