I read one forum and guy say his mechanic tell him.

I copy his words not my word.


I had a mechanic tell me I am screwed if the truck has not had the plugs changed yet at 64K. He said they freeze in the head ! If this is a common problem?


What you think? I don't believe it. If it stuck then why all 5.4L in 90's keep spit spark plug.

Is this fake or it true?

 

Some DO get stuck, even in the other engines in this family.
Even if the plugs are suppose to go to 100,000 miles, I prefer replacing(or even checking them sooner) just so they will come out easier when you need to change them.

Plugs are cheap, so there is no problem keeping them new(in my opinion).

Water and moisture that gets trapped in the sparkplug socket seems to be the culprit.

When replacing your sparkplugs use a dab of anitseize on the treads, this procedure will save anguish later on.

Also checking your plugs will also keep the sparkplug boot from sticking to the sparkplug(a lube for this is also available).

So yes it can happen, but a 64,000 benchmark is not a standard.

 

Actually it is quite the opposite, they will spit out of the heads. Changing them every 60K is a good number. Most of the assumed reasons for them spitting is improper torquing when new ones are put in. The 4 threads in the heads definitely don't help either.

The 3V 5.4L's have the plugs that are known for sticking in the heads.

 

there is a rotunda kit for this. it taps into the broken/stuck sleeve, a slide hammer is used to extract it.

 

The 04-up 3V heads had the broken off, sticking plug problems.
