Hi I have a 05 ford expedition 5.4 3v triton, spark plug in number four is broken as in not half due to some sticking out, my original problem was the hex was round but then I went down to a 14 so I could tap it on but it just spins also and once I cleaned it out I see that the hex is ate up some and looks like spark plug is broke I will attach pic any advise would be helpful and totally appreciated
