Just had one blow in our 02 Expedition 5.4L. Cyl 7. Where can I get these tools at to retap the threads and all the parts I need. Is there a kit or some sort of website to buy everything I need.

Wife wants me to take it to Ford dealer but I have heard it costs $1500 just to replace one head? Is this correct??

 

PM or email Galaxy, a member here. He rents out the tool you need. Timesert.

 

If you BUY thhe time sert tool and all the stuff you need (grease inserts locktight) You'll be out around $350 and you'll have the tool and some inserts in your garage. Cant remember what Galaxy rents it for. Its easy. If you capable enough to change plugs in one of these motors you can install an insert. Its also a solid permanent fix.

 

Had an insert put in mine thinking Ford would cover it under warranty..and the fact I had it looked at by the dealer when I heard a unusual clicking sound a few months prior to that. I was told then it was a fuel injector common noise on the Triton motor. Heli Coil ended up costing $1500 which the extended warranty I purchased did not want to cover. they said it was a spark plug problem... So they paid half..Still have the truck..but afraid to drive it too far.. Never buy a Ford again..

 

Boy that was stupid! letting yourself get ripped off like that! I can fix any blown plug in my driveway in an hour or so. already bought the stuff. Cost me around $300 for everything.

 

That's because injectors do click and yes,- it is common. A leaking plug doesn't click per say, but I guess that's easy to confuse, but Heli-coil! Ford wouldn't use heli-coil, it's not an approved fix. In fact, heil-coils only last 2 years max, then they blow again.

Fords approved method is "Lock and Stitch"...Period. Paying what you did is ridicules, specially for something that has never held out. Yea, Ford didn't do that, surprised they covered anything.

Never buying a Ford again is your choice of course, but how many mistakes is it going to take to wise up ? It's a well known issue yes, but there's been a way to deal with this problem cheaply, for about a decade. One little search could have saved you headache and money, - you didn't research, - bad choice and yet another mistake. Yea, don't buy a Ford again, - that's the answer.

 

Today I pulled the coil pack on cyl 7, what a pain to get to with all the fuel stuff in the way. It tore up the boot, the spring and bent the electrode on the plug. I tried to thread it back in but no luck.

I found the time sert 5553 kit but its $400+. Then I called a local dealer, they want $700 to do it.

My mechanic buddy sent me this:

Do these work......its a heli-coil.

 

as previously stated, helicoil does not last.

 

I just had a guy bring in a F250 with a blown out spark plug and we repaired the strip hole in the cylinder with out the kit. If you are having any problems with your trucks bring them to BBC Speed & Machine shop in Linden, NJ. we can do things that other shop can't. Give us a call at 908-862-6336

 

Guys/Gals let me ask a simple question (I hope). I apologize that I have not read this entire thread, but am curious if my F150 engine is one that has a plug blow out potential.

It is a 1999 F150 4.6l Triton V8 code W. I just replaced all the plugs at 75,000 miles without any issues. These plugs are one piece and have 9 or 10 actual threads. I can't imagine these plugs blowing out with so many threads.

So my question is: Is it the engines that came with the two piece plugs that are prone to blow out? If you google plug number Motorcraft 12405(SP-413) you will see all the threads I'm talking about. I've never any issues with this engines plugs. Is this one prone to plug ejection?

Thanks

 

No, it's not the two piece plugs that blow out but the 1999 -2003 heads with 4 threads per plug.

 

Thank you Bulejay for what I guess is good news for me.

Looking at my plug with all those threads I'd have to think there would have to be some serious head design or bad aluminum casting to blow out a 9-10 threader. Now 4 threads I guess I could see how that could possibly happen.

I'll have to google that part and take a looksee. Don't post much here, but when I do you guys always come through. Thanks again.

 

does the plug have 9 threads or can you see 9 threads in the head?

 

A 99 is only going to have 4 threads in the head - doesn't matter how many threads the plug itself has. The 8 thread plugs were made to work in both the 4 thread and 8 thread heads.

28 ft/lb, no antiseize.

 

That's interesting but the reach of a 4 thread vs a 8 thread plug is big. I would think these heads were designed for a specific plug? Different heads, different plugs. With that long plug the plug might be in the chamber, the short one not. Am I missing something?
