Ken Macfarlane said: (quoted from post at 14:34:42 02/22/13) Which year? Earlier its stripped threads in head, mid its broken 2 piece plug, newest are very little problems.
I've got 160,000 miles on my 5.4 and it is not going to have the plugs touched until its miss-firing. The cost of the repair for stripped threads isn't worth risking it.
Ken, do you know what head design changes they made in the latest ones?
Never mind, I found it. They got rid of the 2 piece plug, replaced it with essentially a conventional type plug except that the threaded part from body down to tip is a very long (maybe 1 1/2 inch?) threaded area vs something like N tractor plugs where the threaded part is only about 1/2 inch. Kinda like Japanese motorcycles have done for decades on some engines. Sometimes it is best to copy success than use a clean sheet of paper! Also 12mm vs 16mm.
One problem in discussing the "more than one problem" is the 2 valve heads, 3 valve and 4 valve heads and "blow out" vs "long 2 piece twist off".
