My plugs were stuck in the head. I have resolved the problem by taking the head off and knocking the stuck plug out. It was a real hassle to just change the plugs but we could not get it out. Is there another way? I have heard Ford makes a special tool to get them out with but I don't know if it works for my problem. I love my truck but if it happens every time I need to change the plugs I'd rather go to a Chevy. By the way, we used anti seize when we put them back in. I really hope it helps but I really don't hold alot of hope for it.

Ford's 4.6L and 5.4L engines have aluminum heads and with aluminum heads you need to make sure your engine is cold before trying to remove the spark plugs. We repair about 1 head a month (of various kinds/makes of engines/cars) at my machine shop, http://www.KensDMS.com . Most of the time the problem has been caused by someone trying to remove sparkplugs while the engine was still too hot/warm. TimeSert makes a kit to repair the damaged 4.6L/5.4L Ford heads. It is an expensive kit, in the $300.00 range. Their www is: http://www.timesert.com/html/sparkplug.html . Here is TimeSert's video of repairing the Ford head: http://www.timesert.com/html/triton-install.html If you do use neverseize/antiseize on the threads, use it very sparingly. If any of the antiseize gets in the combustion chamber it can cause missfire. I think it is a bad design by Ford on those heads. It is one of their biggest problems we see come into the shop.
