[QUOTE="Ruger, post: 133349, member: 1594"] I was told by a Ford dealership rep about the peculiar history of 5.4L Triton engine spark plug failures. In all candor he told me that the problem is isolated to cylinders 7 and 8. He told me that head temp on the back of the engine is such that plug threads tend to sieze in the head, and when those two plugs are removed there is a tendency to damage the threads in the head. The old plugs are blithly discarded, and new plugs installed on those damaged threads. Subsequently under high loads, the engine may literally eject plugs 7 and/or 8 from the head. That's what the man told me. [/QUOTE]
