my new engine and some confusion

[whitmanink]

hey guys ,
long story short,
i had a 2009 gt 4.6 3v engine,,
it lost a keeper , the keeper jumped away , and the valve said hello to the piston ..

so i got an engine off a place on ebay, and said the year i was getting was 08 or 07 ,(my mind is slipping on that one), but regardless, the engine came , and when it did , it had the old style coolant pipes on it (all like 7)
no biggie , i had my old one from my for sure 09 engine ,, so i installed it,,
the motor came with spark plugs in it , but no COP,
no biggie i had my brown COP still from my 09 ,, and used em,

the cylinder head had a 06 cast on it before i installed it ,,, so i question the year automatically ,..
today i decided to pull a plug,,
under ford mikiloku tech i had my engine quite warm and zipped the front driver side one out .
and the plug had motorcraft pzk1f on it.

now im so confused on what spark plugs to buy,,
mod max sells new cylinder heads and says its any year mustang (06-10)
just so as long as you use the correct cop and spark plug,,

i seen the "how to remove a broken spark plug thread ) on the top of the s197 page ,,
but im just confused as to what plugs to buy cuz the length is different and i dont want missfires or something,because i was clueless..

thanks guys in advance

I did not clean the plug threads for the pic . I zipped it out as is with an impact

Those were the original plugs on the '05-'08.5 engine. The new OEM replacements are the Motorcraft SP547 plugs. Those engines came with black coil boots though. If yours fit your golden, otherwise you'll need the earlier style.

I dunno I have a thread about it on here going back about 2 and a half or three yrs now

But I have the brown cop ... So which plugs do I buy ? This is where I'm at a crossroads

Buy the same plugs that came out of the engine, or same style. The different style plug will not fit.

 

[whitmanink]

yea i was worried that my coil on plugs would be to slim or tight to fit over the spark plugs, but i made sure that they sit as they should and they do,, so i ordered a set of 8 as per dino advice , and im assuming these are a new design and not able to break like the ones i have in..
now when they come today i gotta hope all other 7 plugs come out without a hitch

Not sure if there is an electrical connection difference between Black boot vs Brown. You might want to research that first. If you do need the black boots they're readily available and cheap.

I don’t know about the boot situation, I’ve never looked in to that. I was just talking about the plugs. The old style vs new style 3v heads, the plug holes were different size threads. So they aren’t interchangeable.

 

[whitmanink]

My boots fit fine on the plugs .. I made sure before I even began ..
But none the less. Sometimes a victory won is one that some won't understand....
I got all 8 out
One was a AC Delco or sum thing.. but still zipped right out. I didn't even warm or start the engine to do these 7 today..

 

[Autokyrios]

Maybe I read wrong, but did you say you used an impact wrench on the plugs? Do you have a helicoil fetish? Not something to do on an aluminum head.

 

[JC SSP]

I prefer the warm engine, soaking in penetrating oil and using a hand ratchet but zipping them out with an impact gun is a common method.

And, if you transform your cheap torque wrench to left hand usage and stay below 30 Nm, it will take some time but you will get them out without problems.

Impacting out plugs on a 3v are a common way to prevent broken plugs, though you really only need to do this for the originals. Once you swap in the updated plugs, just remove periodically and shouldn’t have any additional breakage, even without an impact.

It's actually the best way to remove plugs. I've done dozens of plug jobs on 3 valves. When I switched to a small impact from a breaker bar, I quit snaping plugs. Of course, some common sense is required to have success. SMALL impact is imperative. I don't preheat the engine, soak overnight, etc.

lol yes i know this is not normal,, neither are the 2 peice spark plugs lol.. this is how to get them out best chance without breaking them.. ford mikiluko tech on youtube explains it for ya

 

[whitmanink]

i think the plugs that were in there were the new design because the bar around the bottom electrode was welded on ,, and i think thats how u can tell,,

thats y i opted to not heat the motor for the last 7

 

[GriffX]

I guess I have an idea why they break. You have carbon deposit on the plug and on the cylinderhead. When you turn them, both deposits get squeezed together until the plug tip is seized. If you turn it further you break it off. I found lots of scratch marks on the plugs. If you now wait some minutes the carb cleaner will soften the deposit again and you can turn the plug further below the 30 Nm limit until you get it out.

With the impact I guess the high torque shock will crush the deposit or shear the carbon from the metal.

 

[lwarrior1016]

The biggest trick with the impact is to use one that moves very fast. And the warm engine helps to soften the carbon.

I used that same method on my 07 that had the factory plugs in it, with 200k miles on the engine. They came out with no issue.
