Ford v10 questions

timmy!!!!!!!

I am about to change the spark plugs on my Dads v10 Excursion and was wondering if anybody has any tips when changing them out. I did notice the coil is directly on the sparkplug which does not excite me at all.

Been a while since I did one....

BUT, I can tell you the COP is not a bad thing...

Its either 1 or 2 phillips screws holing the coil in place... then, pull it up.

Remove the plug with a nice long extension, and replace. Just do yourself, and your father a favor, and put a little copper anti seize on the new plugs.

Be sure your spark plug socket actually holds on to spark plugs so that you can get them out.

Be careful retightening them because some of those heads were manufactured with a defect and their aren't very many threads there plus they are aluminum. I would recommend following the torque specs for them. If it hasn't popped a spark plug out yet maybe he is one of the lucky ones.

I would suggest that you get new boots while you are at it. They tend to burn through and kill the coils.

I would do some research so you know about these problems. I have heard that any V10 "should" fix this problem. not cheap to fix, but better to know what to exect than having a plug come out at some far away place.

Have you ever seen what these spark plugs look like? They are like no other plugs I have ever seen! And expensive!

The company I work for has a lot of Ford Superduties with the 5.4 and 6.8 engines. The engines with over 100,000 miles on them have been a real problem in as far as spark plug removal - Ford has a TSB on it, I believe. What happens is, when you unscrew the plug only the top portion comes out. The extended bottom portion (look at a new plug) breaks off and stays inside the head, frozen to it by corrosion and carbon deposits. It takes a special tool and procedures to get that part out. Our mechanics have the tool and the training to get the broken part out but those guys who have had a Ford dealer remove it tell me it is EXTREMELY expensive! So, should you manage to get the plugs out in one piece, heed the advice in the post above. Used some top-quality anti-seize when you put in the new plugs, and use a torque wrench!

I have a van with the 6.8 V10. Hopefully by the time it needs plugs I'll be too old to drive so someone else will have to change them!

I have replaced plugs on a few of them. They are not anything special, just your regular old spark plug. There is a repair that can be done to the heads that have been ruined by the plug popping out. It does require a special tool that drills out the plug hole larger, taps some new threads into it, and then you thread in a special metal sleeve (like a heli-coil but not) that the plug can then be threaded into. On one truck I worked on the threaded sleeve come out with one of the the plugs. Never had one break off though, that would suck.

They may not be anything special - but they are definitely not like any plugs I have been used to seeing in my 50-odd years of changing them out. Here's what I am used to calling a spark plug - out of my Ford with a 460 V-8:

And this is what the new plug in the Triton V-10 looks like:

Note that on the old-style plug the threaded portion is at the bottom end of the plug. On the new one, the threads are in the middle. And that long, extended nose is what breaks off inside the head when one tries to remove it. Our mechanics were trying to remove another broken one today. The trick is to remove the broken part with Ford's special tool without having it drop out of the cylinder head down into the combustion chamber. If it does, the head has to come off.

As far as the spark plug popping out of the head, taking the aluminum threads with it, they tell me that occurred only in the first couple years or so of the Triton engine. That has not happened to any of our newer pickups so hopefully Ford got that fixed. My van is a 2007 and I sure wouldn't want that happening to me, some of the desolate places I drive.

I have never worked on one of those then, they must have changed to those weird plugs on the newer engines. The older ones use regular plugs. So is that a dealer only plug then or is there an aftermarket for them?

Right now only Champion makes an aftermarket replacement, and that is what we are replacing the Motorcraft plugs with. Reason is that Champion's design is such that they guarantee that the lower portion of the plug will not break off in the head. My understanding is that they are ~ $20 per plug...that means in a V-10, plugs alone cost $200!!!!!! Hopefully some of the other companies will supply a replacement plug in the future and the price will drop with some competition.

you are getting screwed on plugs. 200.00?!! that insane. i bought mine from the dealer and it cost me under 50.00. maybe they screwed up and i came out on top, did they quote you on coil packs by mistake? heres some bosch plugs for less than a buck a piece.http://www.drivewire.com/vehicle/ford-excursion/spark-plugs/

on a different note my buddy who works at ford said that 99% of stripped out spark plug threads are a result of the owners changing out the plugs while the motor is still warm. he said do it when you have no where to go the next day untill your done.

The "new" style plug is only in the three valve heads not the two valve heads.
