My BIL's F-150

Dont the V10's also have a plug issue. I know my friend has a Expedition with a V10 and had plug issues with it.

cant remember if it was the stuck/broken plug or if it was the spit the plug out of the head because the chitty AL threads in the head issue.

I think a small percentage have been know to spit plugs. Its due to over torque and non use of anti seize. The Ford head leave a lot to be desired due to only have 4 or 5 threads but the post 05's were much better giving more threads when they went to the 3v design giving them a power increase.

I had an '05, 3valve, 3.73 gears and if they got a power increase over the earlier 2 valve, I would surely hate to own one of them :laughing:

Your 3.73's were the issue. My uncle has a 05 with 4.30's and its a beast. He also had a 01 or 02, can not remember, with 4.10's and it was pretty good also. Pushed lots of snow with that rig and pulled 14,000# all summer long.

Small percentage? Under statement of the year!

Both the V8 and V10 engines had problems with spitting and breaking plugs. So either you over-torque them correctly and have them break in the head or torque them properly and watch them fly right out of your hood. :laughing:

my f250 has the 3.73's.. but the 6.0 keeps it powered up pretty good. have only niticed issues when pulling fully loaded trailer inthe mountains..

We can argue this all day long but the facts are I have owned 6 F-150, by BIL has had 3, and my Father has had 4. My neighbor has had 2, my uncle 2 V-10's, and I would say just of the top of my head 30 or so of my boating buddies and clients have had them. The only one I have heard of it happening on is a friends 2002 F-250 V10 with 130,000 miles spit 2 plugs last summer. It was fixed by my uncle at his shop in a afternoon without removing the head.

I am sure there are issues, just like Dodge has the worst auto trannys of the bunch, but it gets blown way out of proportion on the net and we all buy into it. Lets face it, I had trouble with trannys in my Dodge but I have 4 customers with Dodge 1500 series trucks of which 2 currently tow boats in the 10,000# range, 1 in the 8,000# range, and 1 in the 6,000# range with no troubles what so ever.

Removing the plugs from the 3v's is quite easy really, its which one breaks that makes it change difficulty. The main reason they pull apart is the carbon from engine combustion grows on the shaft, when you try to remove the hole for this shaft isnt large enough and you get a binding and with enough force, pulls the plug in two halves. The main thing to try to get them out is, loosen them only a few turns, maybe two full turns if that, just enough to unseat the plugs from the head, spray pb-blaster or similar into the plug wells and let them sit for a good hour and come back, retighten them, and then try to remove them. Normally this works as it loosens that carbon enough. If not, well, you'll have to pull them out with the special puller. Anti-seize is to be put on the shank of the new plug to help with this problem.


Ps- If you're removing the coils please replaced the COP boots at the same time, and minute cracks are whats going to lead to misfires and what not. Linemen test their gloves a lot for any pinholes for this same reason, high voltage will find a way through the smallest holes.

can never seize be used on them ?

i use it on my gasser tractors plugs.

Certainly.

I use Never-Seize on every possible bolted or mechanical fastener or connection I come in contact with. I even use it on hoses that attach to water pumps, exhaust silencers, etc on the inboard boat engine. Hoses change out super easy. A good product. I ran into the anti-seize compound about 25 years ago when I was working in the nuclear power industry, a career field that I spent a lot of years working. They use that stuff on all high-pressure and low-pressure bolted connections in the steam lines......pumps, valves, etc.... Sure saves a lot of headache for changing out any type of maintenance or repair item such as gaskets or valve seats. Better than duct tape by a mile...

Recently had my plugs changed in a 1998 F150 with the smaller 4.6L V8 at 115K miles. Ford dealer and a local GMC dealer warned me of breaking plugs. Went with the GMC dealer as they are more skilled than the competing Ford dealer. Didn't break a plug and came in under budget for assorted maintenance tasks. Great local family owned GMC dealer.

Having a competent tech is worth its weight in gold. Glad you found the right man for the job, even tough it was at the GM dealer. I am sure they earned your respect and thats what they should do. You could be a future customer for them and they want to treat you right. Too bad the Ford dealer in your area is not up to par. Maybe they should steel a few guys from your GM dealer. Either way, sounds like you found a good place to get your stuff worked on.

A friend ran into the same type of thing. He had a Mustang he wanted painted and after all the checking around he got it done at a Pontiac dealership. This was back in the late 90's but the same type of deal.
