ok ive been researching for hours now! im going to try to change my spark plugs!

are the best one to put are the motorcraft or there is out there a good alternative for these plugs?

any really good tricks for them not to break! thanks for your help guys

 

Motorcraft SP-515.

Before you change them, I'd recommend you run a couple tanks of gas with Techron added and drive it like you stole it.

You can try following the TSB for removal, or you can try an impact on a warm engine. Either way, have a Lisle tool available.

 

what is techron?

Although I did following the most recent TSB, I also relied on my experience back in the 1970’s when aluminum heads & intake manifolds were just entering the street scene and never-seize did not exist. Here are the exceptions to the TSB that I did…
1. I ran Lucas fuel injection cleaner, mixed at 3 times their recommendation in 1 full tank of gasoline. Purpose…if I was lucky, it would dissolve or loosen any carbon buildup (although many do a real fuel injection cleaning also- and it is probably a best practice to do if you have more than 45-50,000 miles on the plugs)
2. Although I am a fan of PB Blaster, I used a product called ChemSearch “Yield”. The issue I have with using carb cleaner is the lack of lubrication…..in the old days of removing steel plugs from aluminum heads, we use to mix up acetone & ATF…or of we needed more lubrication, kerosene & ATF, “Yield” provides this lubrication- much better IMHO than even PB Blaster.
3. Yes, I put anti-seize on the plug threads (I know the TSB says not to)
4. Of course…a lot of patience, I really doubt if I ever put more than 20-25 lbs of force during removal (purposefully)
The end result, only one plug even “squeaked” coming out (but it basically unscrewed like a regular plug- literally). Plug #4 was initially a little stubborn, but after the second try, then waiting about 30 minutes, it came out with very little effort…just kept wiggling the plugs (tightening/loosening) by 1/8th or even less of a turn- and they all came out without a single one breaking or any issue really. Another technique that can definitely be used is to loosen the plugs about 1/8 to ¼ of a turn, start the engine for about 1 minute- this allows the flame to travel up around the plug to burn off the carbon, let cool, then remove with the process I previously described.
As far as using an air ratchet, I can understand the theory of “shocking” the carbon loose, but I have also seen and experienced in my younger days some real disasters.
Actual working time: 2 hours…..including washing my hands, total time was 5 hours.

 

Techron is a gas additive made by Chevron that really works. Available at Walmart, it's about 6 bucks a bottle. It will help loosen and burn off the carbon that can cause the plugs to break when you try to remove them.

 

can someone explain to me this, im mostly french not english im not shure what this is?
