Why does the TSB only reference 2004's? Doesn't this issue apply to 05's?

 

I think it applies to 2004- 2007. I haven't heard of any head redesign.

 

Ain't that question a hoot!? I will be putting anti-sieze on my threads.

However, can anyone think of why FORD would NOT want ant-sieze on the threads? There's got to be a reason for this.

CMOS: Thanx for the TSB the more I read the more nervous I get what a complete design nightmare!!!!!

 

why FORD would NOT want ant-sieze on the threads
________

all I can think of is that anti sieze might cause more galvanic corrosion between the aluminum and steel. Probably wrong though.

 

They may be afraid that the plugs will loosen up with anti seize on the threads like the early design plugs with only 4 threads???? I don't think there will be a re-design until the 6.2L engine and I wouldn't bet on that. I read a thread from a ford tech and he owns an 04 and he said he was going to drive it to a 100K then dump it that is what a poor design these heads are!!!

 

the TSB says to put anti-sieze on the threads and NOT the anode. The antisieze won't cause galvanic corrosion either.

 

Tylus, it doesn't read it that way. See text below:

"ONCE THE SPARK PLUGS HAVE ALL BEEN REMOVED, NEW PLUGS SHOULD BE INSTALLED USING A FILM COATING OF NICKEL ANTI-SEIZE ON THE GROUND ELECTRODE SHIELD OF THE NEW SPARK PLUG. DO NOT COAT THE ELECTRODE STRAP OR THE PLUG WILL MISFIRE. THE NEW PLUGS SHOULD BE INSTALLED WITH NO LUBRICANT ON THE THREADS AND TORQUED TO SPECIFICATION, 25 LB-FT"


Pretty clear I think. Still not sure why. An above member mentioned thet FORD may be concerned about the SP loosening. That's a possibility...

Once you remove the plugs and look at the shape of the plug vs the shape of the hole I think the issue is better understood...looks to me like it's the "ground electrode shield" as Ford calls it in the TSB thats causing the problem of getting these out after some carbon has built up. I think they're trying to prevent the carbon from building up on the "ground electrode shield" with the anti-seize. I have a picture of the plugs but I can't seem to get it to copy here.

 

Agreed. Ford appears to be trying to reduce the rust/carbon on the elongated ground electrode shield.

TSB 06-15-2 refers to 2004 thru 2005 5.4's for plug removal instructions. I also think it's due to the extended plug design. There maybe an electrolysis effect of aluminum against the plug material (dissimilar metals) causing enough corrosion to weld the plug in place. An anti sieze material prevents this from happening.
Wasn't there a redesign of the plugs! I thought there was!

 

There is no electrolysis between the aluminum and the plug. It is carbon build up that binds the ground shield as you turn it out and causes it to come apart. That's why it's important to follow the TSB, but I have found that waiting at least 30 min or longer for the penetrating oil to wick around the threads and work on loosening the carbon will give you good results.
And the Kroil brand penetrating oil is the best for doing this.
I've gotten many plugs out on high mileage engines doing this.
I've also brought the engine up to operating temp before doing this much to the displeasure of the people I work with

 

Where can I buy some of the Kroil penetrating oil?

Ok I gotta ask...what's UP with these spark plugs for crying out loud?
I was hoping to purchase one of these (06-7) trucks, doing research here. I stop by my machine shop and ask a friend what issues do you see with the 5.4 Triton engins. He simply says..."the spark plugs blow out of them"...and he was serious!

So now I'm reading that the newer engine have a pretty good chance of the spark plugs breaking in the head...WTF you gotta be kidding me right?

I almost had heart failure once when I tried to pull a bad (swollen) Glo-plug out of my Ford Diesel. Thought I was going to pull the head but after 4 hours on one glo-plug and a lot of bad nerves I got it out!

I've always used anti-sieze on spark plugs w/alumium heads ...it's a must!

So now I gotta be sweating bullets about a simply spark plug change...?
And I thought changing plugs on my Vette was a PITA...

 

This ain't no joke ford uses a long reach plug which builds up with carbon and the hole in the head is so small the plug with carbon won't fit through it and when you screw the plug out it pulls in half andleaves the ground electrode int he head which then takes a special tool to get it out which only ford has and if you should loose it in the head then you have to pull the head very expensive not sure if they have made any changes for the 07 model year heard they were coming out with a new style pug???? Would do a lot of research before I bought another one!!!!!!!!!!!!!
