Report: v8 in ford explorer and other models by ford
Ford Explorer Problem
Model Year Affected: 2002
Engine Affected: 4.6L V8
It is actually a COMMON thing for the rear passenger side spark plug to blow out. it is obviously a defect but Ford will not ackklnowledge it. My personnal mechanic repalces at least 4 a month and the ford dealers own service manager said they replace as many as 3 a week. thanks Ford for making us all look like fools.. oh by the wa. it is not cheap to fix unless you want to take a chance like I did and buy the kit, but good luck because the there is a punch that is suppose to bevel the insert, but it is not long enough to reach the insert to use a hammer to hit it.. most mechanics tell me they just attach the insert to the spark plug and screw it into the rethreaded hole.
