Thread: f-150 5.4L blowin plug

Tweet

the 05 doesn't have this problem its 99-03 that has the problem, ford didn't thread the plug holes deep enough in the heads apparently and so when you get to about 70k the problems begin....there was a class action lawsuit filed against ford on this and the courts ruled in fords favor so they didn't have to have a recall and replace everyones heads......

well i got in a big dispute with the local service rep here at ford, and he ended up making a deal with me $1000 bucks is gonna get me a brand new crate 5.4L with the 2v heads still but they're the ones that have the spark plug problem fixed..... the engine also comes with a lifetime warranty.... so now when i put a few hundred thousand miles on my motor, they'll get to rebuild it for me for free
