Alright gus i got an 05 f150 5.4 with 180,xxxon the clock it was studdering realy bad had multiply misfires so i took it in to the dealer the told me there was a problem with every cylinder, 2 plugs broke an one the threads on the plug were completly gone. the options are buy a new head for 3 grand? or a new engine?With this many miles im leaning towards a junkyard engine or somthin guys a need some help!!!!!!

 

Who's gus?

 

guys lol

 

Doesn't sound like a proper diagnosis IMO. Did you bring it a Ford Dealership ?

Well, I'd compression test it anyway. At least that will tell you the condition of the engine. I'm not as familiar with the 3 valve, but a 2 valve can get 300,000 miles fairly easily. From what you posted above, the head doesn't need to come off for that repair.

 

yes a ford deleship, an they said they threads for the plug were gone in the head?

 

Yea, that's an easy fix with Time Sert. If that's not big enough, you could install a Big Sert. All can be done without removing the head.

Regardless, compression test it first, to determine internal damage IF any. You would have to either thread (tap) the plug chamber and use a reducer of some kind to test compression the way it is,- or just go ahead and sert it, - uknow, fix the thread-less hole so you can achieve accurate reading.

But, -if you can't do this yourself, you r pretty much at the dealerships mercy. You can rent a Time sert/Big sert kit for this job. It's an option.

 

Timesert on a 3 valve? You sure that's possible?

 

Yea, I've seen the kit somewhere..

Yea, here-

Sounds like a crummy service department.. I'd take it somewhere else..

 

yes they are this is the secondtime ive had problems with themi want be back, this is acctualy my freinds truck an he decidedto get a new engine because of the miles, an i found a guy to to the whole job for 3900 dollars so thats the descion he made, but i will no go back to Marler ford of tioga louisiana

 

Is the 2003 5.4L a 3V?

 

Its 2005

 

"Not recommended as an over the fender repair"...........

 

Well, that goes for the 2 valve as well. They all say that lol. But like the 2V, the 3V can be done over the fender. Takes a little common sense with handling the shavings.
