So i ran my truck in the driveway while I cleaned the garage and took the motorcycle outside. It got up to basically full operating temp.

I then pulled it inside, well half way b/c of the lift it won't make it in all the way.

I then pulled all of the wires from fuel rain and COP's I pyulled the far right connection at the PCM and the one on the firewall over it.

Took the cop's out, blew the holes out with my air compressor and all around the engine to prevent debris falling in.

I set the torque wrench to 30 lb and started to crack the plugs loose with the OTC 6900 extension I bought, it was too short so i had various extensions on the whole time. But still worth the $30 bucks

So i cracked the plugs as far as they would go, anything from 1/16th to 1/4 of a turn.... I didn't push my luck i took what i could get.

I then filled the holes with Gunk Liquid Wrench Foaming Penetrant & Lubricat L4. Let them sit for about 40 min.....

I brought the shop vac out and sucked the holes clean, Started to slowly remove plugs. It was Super screechy, I went back and forth, back and forth. The torque wrench was set to 27lb b/c that is what they are torqued to when installed.

so everyone one came out perfectly.

That Kinda makes the Mac Tool Ford spark extractor set (PE391FC) i bought useless till i due some buddy's trucks later in life.....

I vacuumed all the holes again when the plugs came out and followed procedure when installing the new Motorcraft SP-507's

Its not so bad, buy the tools and try it out. If your in the Windsor, Detroit area and want a helping hand maybe we can work something out.


oh ps. I did manage to somehow loose one of the COP bolts, no idea how or where...... Nothing is perfect I guess.

 

Thats great that you had no trouble. Glad it went smooth for you.

 

Great job. I think I am going to do mine at 60k. How many miles were on your plugs?

 

just shy of 100 000 km

 

wouldnt say shop vaccing those flammable liquids and vapors would be that great of an idea but if I recall, I did the same thing... I did leave pb blaster in overnight before even giving a crack...

 

Ive got 102k on my stock plugs. Probably time to think about doing this.

 

yea probably so =)

Here I was thinking I was pressing my luck at 85k.

 

sweet bro, good that someone has done a flawless job it gives the rest of us hope for I myself need to consider doing this im bout to hit 80k, wish me luck

 

Been debating whether or not to attempt this on my own, changed plugs when I had my 93 Mustang but my 06 5.4 is a totally different beast. And my truck is my daily driver so I can't afford to have it not running (i.e broken plugs) was thinking of taking it to the dealer a minute or so from my house or another reputable dealer in the detroit area. Still not sure what to do now that I hear about the 3rd updated TSB.

 

At 103,000 miles I decided it was time to change my plugs and after the dealer quoted me $350 plus $100/hr for each broken plug they had to remove I decided to change the plugs myself. It wasn’t as bad as I thought it would be, it’s a matter of having the right tools for the job.

I purchased new Autolite plugs ($100) and the push/pull removal tool ($70). I followed the TBD exactly and had 6 of 8 plugs break. The tool pushed the ceramic down far enough to allow the extraction tool to pull the electrode shield and ceramic out of the head. After removal I used a shop with a small hose attached and vacuumed out each cylinder. I installed the new plugs, put everything back together, and everything ran fine. Now if I could just get rid of the loud ticking issue the engine has.

I definitely recommend tackling this plug change yourself if your somewhat mechanically inclined. It should take about 3-5 hours to complete. Just depends on how many plugs you break and your experience working on engines. The important thing to watch out for is broken pieces of the plug being dropped into the cylinder. This could result in very bad things happening to the engine. I cranked the engine over while applying a vacuum to the each cylinder before installing the new plugs to make sure no small parts of the plug were left in the cylinder.

If you have questions let me know, I live in the Detroit/Flint area.

 

Great job!!! That is a lot of miles for such a success rate! I vote do it your self 100%. I know these guys here have your back

 

i have 133,000miles on my stock plugs i have had a set sitting on my desk for the past oh 10k miles waiting to go in, just havnt gotten the nerve to do it yet

im thinking the majority of the plugs breaking is due to faulty removal methods...such as not using a 9/16 spark plug socket...

 

so basically you followed ford's TSB on how to do it.

 

what plugs did you guys go with?

where do i get this removal tool? and where can i locate this tsb to follow instrctions??

one other question, does anyone want to come help me?

 

I'm at 101k. Looking for a place for cheap Ford spark plugs. Getting quoted over 18 bucks at the local stealership. then next is to get the right socket and removal tool. Been running Valero gas for most of its life. Don't think it's a top tier gas nor does it have much cleaning additive. I've got 4 tanks of top gas so far. Gonna go for 10 tanks before I even consider it. Hopefully it'll make a difference. I know the truck engine feels just a tad smoother especially acceleration but I'm sure the weather has a lot to do with it as well.
