I bought this truck about a year ago with 85,000 miles on it. It ran good and was in good shape. I was very happy with my truck. Pulled the horse trailer and my equiptment with no fuss. Put about 8000 mile on it. About 3 months ago, I was starting it up and it made a loud pop and then some major noise as the engine ran. I shut it down and found that a sparkplug had came out of the head. It had broken the special bakalite holder on its way out. I went to the local Ford store and got a new plug and plug holder-$125. They knew exactly what had happened and said it was common for this engine. I put everything back together-the plug seemed to go in normally and tightened just like I expected it would. Now today I was 5 miles from home when I heard the pop and noise again . The same plug is out of the head. The engine is loud and has markedly less power. I drove the 5 miles home and am now wondering what course of action to take. 1-It's a used truck-no warrenty. But Ford and it's dealers knows that this engine has plug problems. 2-Did loosing the muffler a while back contribute to this problem?
3-Did driving the truck home hurt it?
4-Any suggestions/experience in this matter?

Thanks in advance

you will obviously need a spark plug.. i can not give you a certain yes or no as to if youhurt the head but i am guessing that you didnt do the threads a whole lot of good that used to hold the plug in.. but then again if the threads were any good to start with you would not have this problem. loosing the muffler had absolutly nothing to do with this. i would have a chat with ford if i were you telling about this. you never know it may sink in with them

Two thoughts here 1. Ford has been making cars/trucks for 100 years and still cant install a spark plug! Yea got to have one of those 2. Why would any one want a v10 and not a diesel???

Jocco made the best comment on here being ford has been building cars 100 years and we now have spark plugs blowing right out of the heads. Maybe they should call briggs and stratton to find out how to do it right. Ford quality is in serious trouble. They now rate so low it is pathetic. I have a whole yard full of them and I can honestly say never again will I get one. I am in a constant state of fixing and repairing daily. I have the 5.4 in one of them to and I am sure the plug will blow out of the head someday soon. Probably the back one under the firewall. Ford needs to be put to sleep!

Biggest debate on the FTE gas vs diesel- my reason? 1.5000-7000$ initial cost vs 685$ v10
2. diesel fuel= more expensive, smells bad and can be hard to find when traveling
3. Turbo lag
4. HPOP issues on 7.3, 6.0 (numerous issues(whata joke- already discontinued)
5. price a turbo
7. I can pull 25000lbs faster from a stop and up hills than the 7.3 and 6.0 (yes I will use more fuel)
8. My V10 Quad 4x4 is nearly silent at 85mph- ever try to talk in the PSD?
9. I can get 250K miles out of the v10- I really don't want to drive a truck more than that so its irrelevant to me if the PSD will go 400k
10. Dad-in-law and brother in law (both PSD owners) will never own gas but both agree- D@*&, that V10 is STRONG!!

Aside from being much cheaper to buy and still doing the same work as a diesel I really couldn't guess why.

If you don't tow/drive it everyday a diesel will be hard pressed to pay for itself in a remotely resonable amount of time.

Common problem prior to 02 when the head was redesigned to increase threads holding plug in. 3 choices- helicoil, replace head, sell truck. Helicoil is recommended and the FOrd Truck ENthusiast web site says do ALL plug wells now- don't wait. (go there and you'll find a v10 board just for this engine) THey will walk you through this and the head doesn't have to come off to fix. Be sure to use antisieze compound and torque to 14-16 INCH pounds, and change plugs around 60K miles NOT 100k. You have a great engine good for 250K miles- fix plugs and you're good to go. You'll find lots of info at FTE web site- good luck

You'd be right- I recall now it was like 168inch/lbs or 14-16ftlbs. (please see the FTE website to verify as the # is critical!)David

I personally know two people whose Ford trucks have blown spark plugs. One was a V-10, the other a V-8.

The first guy pulled the head off his V-10, had it helicoiled, then he got cold feet and opted to buy a new head. The head was close to a thousand bucks from the dealer. He was not an experienced mechanic, and he said he couldn't have done the job without the Ford factory service manuals. Changing the head on these engines is apparently a real bear. He got rid of the truck after this experience.

The other guy was a contractor who blew his out in my driveway. He bought a thread chaser, which didn't help a bit, but came in useful in plugging the hole so he could drive home. (We had to weld a 3/8" drive torx adapter to the thread chaser just to use it, there's no room to use a 13/16" plug socket on the chaser.) This guy couldn't afford to replace the head, let alone the downtime for his work truck. He opted to go the helicoil route and repaired the head on the vehicle. That was a month ago and the truck is running fine today.

I understand that someone in California tried to sue Ford over this problem, and failed miserably. The case was dismissed in favor of Ford and was not certified for class action.

The Ford fix is to replace the affected cylinder head. There are a couple of aftermarket repair kits dedicated to Ford spark plug thread repair. I've used the one by Lisle with success but, these kits are a few hundred dollars. The arguments are split between over tightening when the spark plugs are replaced to poor cylinder head design with only a few threads as to why they plugs blow out. I don't think Ford has any plans for a recall or a free fix. You're operating on one less cylinder so, there is going to be less power. The noise is from the compressed air fuel mixture blowing out with each stroke of the piston. There's really no way around getting it fixed. The choice is yours to replace the head or to try thread repair. I would choose thread repair by someone using one of the dedicated thread repair kits. Lastly, I always use a torque wrench when replacing the plugs on these types of Ford engines as insurance.

Some good info below. If it was me, I'd try the heli-coil (thread insert) route first, as you really don't have anything to lose except your time and the cost of a heli-coil. If you're careful and reasonably mechanically inclined you can do it yourself. Coat the tap with grease & clean it frequently to minimize the chances of chips falling into the cylinder.

To answer your other questions:

2-Did loosing the muffler a while back contribute to this problem?
No.

3-Did driving the truck home hurt it?
Probably not. The only concern I can think of would be unburned fuel washing the oil off the cylinder walls, but with it breathing through the plug hole instead of the manifold you probably didn't get much fuel into the cylinder anyway.

Good luck. Don't forget, it's a Fix Or Repair Daily (actually, I own/have owned several, but never one with the V-10).

It appears that blowing out plugs on the Ford 5.4 V8 and the V10 is fairly common. Most dealers would rather charge you three grand for a replacement head, others around eight hundred for an insert that is only temporary. The problem is only four threads cast into the head just isn't enough. Maybe someone out there has a fix for it, but so far it's still going on, Ford has closed their eyes and ears about it, and no-one has properly solved the problem.

No personal experience with this problem, but have read a half dozen or so threads about repairing those aluminum heads that came with too little thread in the plug holes. They mention a relativly cheap repair that involves drilling and tapping the plug hole while on the engine and installing a threaded steel insert which is a permanent fix. None have mentioned any damage from the few bits of drilling/tapping aluminum that an air gun may not blow out of the cylinder after the machining is done. Aluminum is pretty soft and not likely to score anything before it blows out with the exhaust.

Another comment in those internet site threads about plug thread failure in Ford aluminum heads is that their is a specific torque spec for the plugs. You must use a torque wrench to tighten the plugs and coat the threads with antiseize compound. I also seem to remember that the plug tightning must be done at a specific engine temp. (cold ? )

Apparently the "approved method" is a thread insert being installed.

As I also have come to understand from finding this dilema interesting and reading about it is....

that sometimes, on some models, if it is one of the rear most plugs, getting a thread insert installed can be a problem. And on some models the appropriate repair method includes removing the truck cab, or body to access the motor.
