While back I remember reading the 5.4 Ford had problems with spark plug threads, in the heads.
Stripping out and problems getting it fixed, or replacing heads etc.
Was this only with older 5.4's???
My folks came across a 06 Ford Crew Cab with 123,000 miles, just wondering if this still was a problem??
