Just wondering how common my problem is...
99 ford f250, v-8, and ive had the heads replaced three times, due to spark plugs, popping out. Its nothing i did, they were original plugs, and it started at 12,000 miles. Since then, it happened two more times.
I hear all of the modular motors do this, even the v-10. Due to not enough thread engagement.
Anyone else?

 

I have only heard of the 2000-2002 5.4L having this problem.

 

Look up f150online.com and you will have a ball looking up infor mation on this issue

 

Yeap just like TIC Said.

 

thanks guys, thats what im looking for.

 

Its a ford!!!!!!!
