The Ford spark plug problem (plugs blowing out of the head) was in the very earliest versions of the motor. Simply the casting was too thin and not enough threads. Any later version, problem solved.
My 2001 is a "later version".
The Ford spark plug problem existed for several years and included the 2 valve engine, that suffered from blow out, AND the newer 3 valve engine that used a two piece spark plug, which if removed without using the proper procedure and a special tool, also caused a major/expensive problem.
