I just bout a 06 F250 V-10 has 126000 on it. I want to lift it 4-6 inches with some 35's. I was told not to because it will start blowing plugs. I was told that between 126000 and 130XXX that they are natorious for blowing the plugs. does anyone have any insight on this.

 

Welcome to the site and congratulations on your new to you truck.
If you use the search function you'll find some concerns over blown plugs but that is involving mostly, the earlier engines. I have a 99 [earlier engine] and haven't had a blown plug. Although I have had one come loose, the tell tale tick tick sound made me look into its cause.
Maintenance is the key to avoiding mechanical problems and thats where this site comes in. This is a great place to help you get to know your ride. Full of great people who all share a common Love for their Vehicals. Snoop around and you'll find lots of cool info to help you personalize your Truck and get the most out of it.
You're in the right place don't let the doom sayer spoil your joy. I can tell you you have chosen a great power plant and your really going to love what it can do.

 

Why would a lift cause it to blow plugs?

 

I was kinda wondering that myself...

 

The lift would make it to bigger tires the bigger the tires the more of a load the truck is pushing causeing plugs to blow.

 

That really doesn't make any sense. If you put a 12K load behind it, that will increase the load too. So don't tow EVER? Or carry an extra 1000 lbs in the bed because it's more of a load?

Nope.

The best way to keep plugs from blowing is to maintain them.

 

I've not heard it being an issue on newer trucks but the engine provides the power to the drivetrain, not the other way. The load doesn't make the engine work harder, the engine works harder to move the load. The engine is designed to move the load, about 12,500 lbs or more.

It comes from the factory with what sized tires, maximum sized option (I'll give you a hint, it's over 34" tall)? Do you think if you got a tire almost one inch taller than stock you'd blow plugs? If that were the case the Ford Super Duty with V10 engine would be the only truck out of the big 3 that you couldn't go one inch taller in tire without exploding. Seems Ford would have engineers working on that round the clock, being they'd be the only manufacturer that produces a consumer truck that does such a thing.

So, what's this all mean? The person that told you that was playing a joke on you, or doesn't have half a clue. My guess is you were made the butt of a sick twisted joke and I'd go punch the guy in the mouth in front of his wife and kids for making me look stupid. But, that's all Internet bravado talking, so you probably shouldn't really do that.

 

humm mine has a "tick tick" sound to it checking plugs might be wise. good idea thanks

 

Here's something to consider: I don't know for sure, but I think the spark plug thing is rare at best. I mean, you don't hear people on the internet bragging about how their V10 doesn't blow plugs, but occasionally, you do hear someone saying theirs did. When I was researching the whole V10 thing, I asked a good freind who was a service writer at the local Ford dealership until recently, what problems he had seen with the V10-equipped trucks and vans. His reply was "zero". I mentioned the plug thing and he said that once they had a 5.4 have a loose plug, but not one came all the way out. He said the V10's were never in the shop except for oil changes, and while they aren't the most common thing among private owners, there are a bunch of them out there as fleet vehicles.
As an interesting side note, last Saturday I bumped into a guy who owns a transmission shop. Just in passing, I asked him if he had ever seen problem with the F250's with a V10 and an automatic. He told me he saw them "all the time" with about 30,000-40,000 miles and scrap transmissions. I asked my other freind and he swears they never saw even one in the 5 years he was there, and I can tell you from my observations, the Ford F250 is far and away the most popular truck in these parts by a long shot, so how could one guy tell me the trannys are junk and another say they've never seen one? I posted the question here and came to the conclusion that the tranny shop guy may have been stretching the truth, if not outright lying. Same as your freind about the plugs, it may be based on a story he heard somewhere, but the odds are in your favor. They ain't selling a zillion of these things 'cause the suck now are they?

 

Hey guys this is why I asked. I thought myself it was fishy because guys do it all the time. And I have heard about any ford blowing the plugs even on the v8s. lol And I have seen a guy blow a plug it was kinda funny he left burnin his 33" goodyears and BOOOM PPPP PPP the rest of the way home lol. Any way that was on the 2 valve v10 also. I just didnt want to do something that wouldnt be good on my truck. thanks for the help guys. Im to big of a idiot just like to investigate before I do it.

 

Nothing wrong with that. I think it's smart to check out things from all angles before jumping in. Personally I think more people should do more research BEFORE they buy stuff rather than be sorry later.

 

I wouldn't take offence to any replies you got. We're very passionate about our Trucks and the V10's that power them.
There are people who have preemptively put thread inserts in every plug whole even though they never spit a plug. What ever floats their boat I guess.
Enjoy your ride and hang. This site is addictive, the moderators and regulars make it a great place to kill some time and learn.

 

Not picking on you, whatsoever, Sand_Man, just laughing at this.

Ask a tranny shop guy if he sees "X" vehicle. He answers "Sure, they all blow trannies". Gee, it's a tranny shop, WHAT THE HELL ELSE WOULD THEY BE GOING THERE FOR?

It's just funny how some mechanics answer questions. Find any mechanic who has done a bunch of plug blowouts on Ford modulars. I bet he doesn't see a whole lot of them for other reasons. Because they DON'T HAVE ANY.

It's like asking a refrigerator salesman, "Sell any refrigerators lately"?

And yes, brand loyalty has a lot to do with it with mechanics. I know a guy, was a "service writer" for a GM dealer. He worked on vehicles on the side, at his house on weekends. He had plenty to say about Fords, but never a bad word about GM vehicles. Of course, he'd take your money and fix your Ford, all the while bad mouthing them up down left and right.

 

LOL!! That's kinda my point. I mean, it's everywhere! I used to own a Honda CRF450R mx'er, and it was the pinnacle of motocross technology. I bought mine used from a local pro, and while I never raced it, I rode it plenty hard. I never had one second's problem with that thing, yet on every internet forum I ever saw or heard of, all you'd read is about the CRF valve problems. It's the bad ones you hear about, never the ones who ride week in and week out and never have one issue. Like you said, it's all in the way you look at it, and who you ask.

 

Ahh I didnt take any offense to anything you guys said. I was wondering on the ticking noise that you guys heard when ur plugs was loose was it a constant ticking or did it just tick when you started it and it went away in a few seconds.
