Well, I have to say, maintenance is not high on my priority list. I tend to drive/ride/use things to destruction. Probably not the best way but maybe I should apply for a job someplace as a "real world tester" of trucks, bikes and construction tools. I seem to do a good job on tools especially. My bike is in good shape (knock on wood) and the truck will be back on the road Thursday for some new punishment.

When I lived in Ireland, I used to rally Fiats and the only time plugs were changed was when I blew/siezed a motor and replaced it! Oil only went in the top to replace any that dripped out the bottom or burnt from failing rings...

~Didn't I read someplace here that the Ford factory plugs were supposed to be good for 100K?

 

I was talking to a mechanic friend this weekend.
I only see him two or three times a year at the Dragstrip, I was telling him about a Truck I was looking at with a v-10.
First thing out of his mouth was that they spit plugs.
He sees it all the time.
Hes a chevy guy,I am a ford guy so I thought he was just taking shots while he could.
So I looked into it.
Seems that the #3 hole only has 3 to 4 threads holding the plug in.
Its the most common hole to poop out a plug.
The V-10 seems to have the most trouble next is the 5.4.

2003 heads changed to 5 threads.
Kinda sucks if you ask me.
This is a ford problem and ford needs to fix it.
I think I will stick to the push rod motors for a while.
Its kind of embarrassing ford would put out a motor like that.

 

it was 2000 they changed the heads. and he's a load of bs .when done by the book they don't spit plugs . ever count the threads on a lawn mower plug 5.


as to your post don't come down here starting things off with the guys who drive them every day and know a lot more then you or the bs gm racer guy. stay up in your cast iron area

 

O my...thanks for biting my head off.
OBTW I dont think your driving a lawnmower.

 

no trolls in v10 man and yes i drive a v10 and so dose my brother 2000 NEVER SPIT A PLUG.
as to lawn mowers they spit plugs to if not torqued to spec.

 

Take the comment from the Chevy guy for what it's worth. Nothing.

All the holes in my 2001 had the same threads, 7-8 total. NEVER heard about a different number of threads in one cylinder EVER here in the past 5 years of some definitely knowledgeable people talking about it.

If there ever was a cylinder with a lesser number of threads, that went away in 2000. That's only a 2-3 year run of the motor, and it's still going strong 8 years later.

 

The three threads info didnt come form my friend it came from the link.
Did you even bother to read it ?
Captain Charlie posted.
Charlie I am not a troll.
I was just giving my 2 cents.
I hope you never do blow a plug.
I think ford made a mistake and needs to deal with it.
look at this link.

Now this one

They spit plugs.
Ford will lose buyers.
You can close a blind eye to it, but it wont go away.

 

Hey Minnesota man...

You are awful quick to ask if any body read your old news... it is certain you have not read the entire thread or all the plug blow out postings on this the best Forum for ALL things V10

seems like you want to be mad at ford and you clearly say you will stick with push rod motors

Cool that is you right and choice... but I can assure you that the problem was never a serious defect and that your stubborn acceptance of third hand BS is causing you to miss out on the BEST motor any American manufacturer ever put in a pickup truck

This problem is almost always tracked to corrosion induced thread failure and too loose or too tight makes it worse.. and Just so you know Ford fixes every single one of them that happens with in the 36/36000 warranty..

You want to bash FoMoCo V10s please accept our polite invitation to do it on some other web site.... or if that is too much to ask, then spend some time educating your self on what the issue really is, and what is it about a Ford modular overhead cammed motor that can out pull many diesels and EVERY push rod motor Ford, Dodge, or Chevy ever made!

 

Fredvon4 it may be old news to you but its not to me.
I just learned about this defect on saturday.
I didnt post here to bash the V 10 mod motor.
This was the 3rd thread on this form.
I also understand how you would come to defend a motor you love.
sorry If I offended anyone.
I do have to disagree though this is a major defect.
I also think ford will lose buyers who get burned by this defect.
I will still buy ford.
Some wont though.
Just like maticuno.

 

Well, I guess there was bound to be a fight on this sooner or later. I am agreement though that Ford screwed up and the V10 does spit plugs. I know, we all hear about the aluminum heads and how they will spit plugs no matter what brand... Well, I have driven a lot of Toyota, Honda and GM's with aluminum heads and never even thought about the plugs. Now, I am always thinking about changing my plugs because I don't want them to spit... then again, I don't change them because I am afraid if I do, they surely will spit.

OK, Having said all of that, I love the V10. It pulls hard all day long for me and runs very smooth. Every engine has its issues, the 460 used to run hot and suck gas like a pig, the 454 was toast if it over heated one time, the GM's with the central point injection were always in the shop for fuel system problems. All of these were great engines, but they all had their vices. The V10 is the same. I am conviced that they spit plugs and having to change plugs at 25K to make sure it doesn't is crap... no matter who says it is not.

I like the V10 a lot, I drive one now and will for a long time. I have a 5.4 in the driveway as well, and will for a long time. Still, when and if either spits a plug, I will fix it and move on. At least I will know what the funny sound from under the hood will be when and if it happens

Let's not fight about it... life is too short to get all hot about it, the V10 is what it is, good and bad.

 

Some of you helped w/my engine miss post. I'll tell you my v-10 was only running on 8 most of last week-end took 300 mile round trip to Ford Nationals at Carlisle Pa. Average early AM speed was 85! Try pulling two plugs on a chevy or dodge doing that! If she pops one so be it- like the man said fix her and get on with it! No body builds a perfect one!

 

ford did fix it in 2000 with a new pe head design and again with all the 3 valve mod . motors the 4.6 ,5.4 and 6.8 with a specail new plug that looks more like a glow plug then a spark plug .it's called a thread over as the threads are ontop of the tapered seat at the very bottom , just like a diesels glow plug. even uses a 9/16 special mod motor plug socket .
next time you see that gm jerk at the track tell him he's miss informed and full of horse/cow dung

 

Please don't get me wrong I am not saying this is not a serious problem and that any one with a Modular motor should not be concerned

If it were not for these internet forums MOST of us would never know it happens

And if you try to find a similar forum for Toyota, Nissan Honda or what ever you will find a few but none with the depth of this Ford Truck Enthusiast site... So the point is just because you owned plenty of "other" brand aluminum head vehicles and they never spit a plug on any of your vehicles, you can not make the claim that they NEVER spit a plug....

I had a Nissan spit one, I know of an Audi that did too.. from those experiences and knowledge would it be fair for me to claim all Nissan or Audi motors are crap...of course not.... I am pragmatic and fact based guy and not driven by emotional irrational fear

The only way Ford looses customers is the rare times when the service folks screw up the and make the customer feel like it was his fault. I dare say my experience is totally different, FORD has fixed this problem time and again under warranty, Ford was relatively quick with the upgraded head and plated plug, and it would be totally unreasonable for any company that is bleeding red ink to do much more then that... go ask Chrysler owners what they think of the minivan transmissions from the mid 1990s that crapped out by the thousands and the factory was totally unresponsive... there was a customer looser and Toyota and Nissan sold boat loads (literally) of minivans because of it.

Fact the plug blow does happen
Fact MOST of the time it is preventable
Fact if it happens in the first 36/36000 OR under any of the extended service plans sold by Ford, it will be repaired (maybe with a deductible if that is you policy plan option)
Fact plug blow out is rare
Fact NO company on the planet can make a 100% defect free product.. and any product that has over 10,000 parts and assemblies is bound to have some degree of defects... that is what warranty programs are all about

Opinion if a plug did not blow in the first 36/36000 the odds are good that they were NOT OVER TORQUED at assembly
FACT, knowing these facts requires you to check or have you plugs checked

Sure is funny what peoples perceptions are... OK it makes sense sort of... every now and then we hear of a plug blow... and some folks make a issue of it and claim the big bad company is robbing us blind and should not get our money

Funny.... in that the IAC is a MUCH more prevalent failure in all 1999-2004 5.4 and 6.8L SuperDuty trucks and E-series vans... literally MILLIONS of vehicles and almost ALL of them experience this component sticking and needing cleaned or replaced... nobody ever jumped in here with a "I hate FoMoCo" because of the IAC

What does that mean? we are OK if a $100 part is crap, but the extremely rare $1500 plug blow out is such a giant sin?

 

o how correct fred.

42 years i slaved as a mechanic/ service writter. manager. mostly for vw . they blew plugs out before any one else . esp on the old air cooled motor. still do from time to time with the water cooled . and when they do it's poor or improper maintinace and repair. many a time i would work on motor and hear pop,pop,pop from aplug after someone pulled a driveway job and not knowing how to use a torque wrench.

it's not just fords 4,v6, v8 or v10 mod motor its every alloy headed motor out there . new plugs use a torque wrench and get them in correctly and no problems.
as to v10's ford was very fast in up dateing to the pe head for more power and better head threads for the plugs.
so a early on pops one now and then. fix them all the first time with one of the kits out install the new type inserts and stop wearing a worry bead set.

 

I never said it does not happen to any other motor. What I did say is that Ford has an issue on this. You guys crack me up. I like the V10 just as much as you guys, but come on already, the darn thing had a design issue. Geese, it is funny how if you say anything contrary to the Ford SD or V10 are terrific than every conceiveable defense comes out.

The modular motors have had many complaints to the regulatory agencies on this ... not ever manufacturer can claim that wonderful acheivement. As it relates to the DCX transmission that Fred referenced, yep sure was a bad unit, and we all acknowledge that it was, why can't we just be real and acknowledge the modular motor plug blow issue?

Seems to me that Ford had huge issues with the EGR valves at least on the 4.6, but it never left me standing on the side of the road. And that there is the major difference I think. Vehicles of any kind are mechanical creature, airplanes, boats, cars, trucks ... mechanical items will break, do break and are designed improperly, fact of life. But the difference between and issue and it's severity is sometimes not only what the cost is to fix it, but did it leave you standing on the side of the road or having to pull you vehicle out of service for an extended period of time. Yep, when you blow a plug it will sure do that!

Like I said, I like the modular motors and my V10 does a great job for me, no problems at all. But having said that, I can't see why we should just stick our head in the sand and deny any issue that the thing does have. Starting to seem like I am on that diesel site

Not wanting to start a fight here, just being real.
