I was wondering if I should be prepared to have to replace my heads, or repair a blown out spark plug in my 97 F150 with the 5.4L V8. I see all over the internet people having spark plugs getting blown out of the heads of the truck. Should I brace for impact, or sell the truck?

 

It doesn't happen to every one of them, but it is a common issue. I think selling the truck may be a little drastic if you haven't had the problem.

 

I had a helicoil put in about 30k miles ago, all is fine.
