When you put the new Motorcrafts in be sure to cover the shank with nickel anti-sieze. They should then come out fine, next time. Also, what are you using to soak the plugs?

 

motorcraft carburetor tune-up cleaner for the soak, and the four I already installed I put high temp nickel anti seize on.

I'm just having a hard decision whether to take it to the dealer or not. I know I have the lisle tool coming, but i'm just concerned that it won't work, either way it will be monday or tuesday before i get any more progress.

 

If you're in a rush and don't want to wait on the tool, take a look at this thread:

The only time I have heard of the tool not working was when the threads broke, so the tool is not even designed for that type of extraction. As far as i know, everyone has said it makes the removal very simple.

 

Sounds as if you are doing everything correctly. You are one of the few that has followed the TSB and still had them break. Bet that makes you feel special! LOL

 

LOL it feels awesome,I studied that damn TSB for 5 days straight. I even got the EFI cleaning at the dealership done before i started this project.

 

My dealer service advisor stated that the plugs are much easier to remove if done at
60K miles or before! Your at 84K, that is a possibility of a higher breakage rate, TSB followed or not.....

 

From all the threads I've seen and from talking to the guys at my local Ford dealer I've come to the conclusion that top tier fuels with cleaning additives in them greatly minimize plug change problems, high mileage on the plugs or not.

 

I agree. Bankston has gotten them out with 133,000.

 

My uncle (dealer mechanic) has said the same thing. If you run crappy gas, it doesn't matter when you try to pull them, they are a nightmare. He told me to wait till 100,000 to change them, his experience is that it doesn't matter when it's done, prior to 100,000 anyway.

 

On my neighbor's 05 F150 with ~40k on it, we broke 1 out of 8 and that was after soaking in the recommended carb cleaner. He used the home-made extractor and got the broken one out. I changed the plugs out in my 06 F150 at the same time. We both went with Champion 7989 plugs and have had no problems whatever. Why put a part with a proven defective design back in your motor? Say what you want about Champion plugs, but at least we don't have to worry about the plugs breaking next time we change them.

 

Because they work best. I've had zero problems with the motorcraft plugs.

 

Me either and with the nickel anti-sieze on the shank, I have no concerns with them coming out at about 90,000 miles. The first ones came out at 65,500 with no problems. Again, I contribute a lot of that to a tech that knows what he is doing and running gas with a good cleaner.

 

It seems to be more a matter of chance or fate based on all the accounts I have read. I'm not trying to start an argument, all I'm saying is that LUCK should have NOTHING to do with changing spark plugs.

 

Well I've never heard of a Motorcraft 5.4 3v 2 piece plug fouling out like the new champion on piece plugs have.

It is though a matter of choice. I choose the proven trouble free performer, Motorcraft.
