The 5.4 spark plug probem was more of a "when changing plugs...the plug would strip out..leaving the threads in the cylinder problem" There are a few diff fixes that avoid an engine removal, but none are real easy.
I had that engine in a Ford motorhome and was told ..."if it runs..don't attempt to replace the plugs"
