This wasn't done by me, these plugs have been in since I bought the car a few years ago, but noted.Next set of plugs smear a little anti-sieze on the threads.
honestly, as far as I can tell no damaged threads so far! Nothing that looks like it needs a threaded insert/helicoil.I expected the plug threads to look worse. How are the threads in the head?
Corrosion or electrolysis must not have been that big of a deal. Frustration and PITA aside, you lucked out that part of the head did not stay stuck in the grooves. I do not know how the AL head was stronger than the steel plug.honestly, as far as I can tell no damaged threads so far! Nothing that looks like it needs a threaded insert/helicoil.
Just insanely seized but I'm very careful with the angle of pressure I put when twisting as to not pull\push the threads, just twist.
Yes definitely, now that the head gasket is confirmed blown I have to have them off anyways, so they will be getting planes/resurfaced, all threads cleaned, etc.Corrosion or electrolysis must not have been that big of a deal.

Are you going to run a thread cleaner/chaser before installing new plugs?
Only 5 left to go!I've seen it with NGK but never a Motorcraft plug (well the older ones anyway)
Man card stamped for getting that out
I’d try an impact on one of them. Since they’re fubar anyways, it might help shake them loose.Only 5 left to go!
Every one of the 3 I've gotten out so far have snapped
Definitely thought about it, I'd have to take headers off to get to them, didn't plan on doing that until heads came off to do the gasket.I’d try an impact on one of them. Since they’re fubar anyways, it might help shake them loose.
I had thought about using one of the "drill type" electric screw gun impacts on them.... it might rattle em enough to loosen them where an Air impact might be a bit much...Definitely thought about it, I'd have to take headers off to get to them, didn't plan on doing that until heads came off to do the gasket.
I figured I'd try to get the plugs loose now to save time later, and that way we can at least do a compression test with the engine still together just to see what it shows.
Me to the spark plug: I got nothing but time MFr. BRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRT.I had thought about using one of the "drill type" electric screw gun impacts on them.... it might rattle em enough to loosen them where an Air impact might be a bit much...
I’d pull the heads off and hit the plugs with the impact when they’re off the engine. They’ll 100% come out then. Beats being hunched over the fender screwing with them since the heads will be off anyways.Definitely thought about it, I'd have to take headers off to get to them, didn't plan on doing that until heads came off to do the gasket.

hit them with penetrating oil on both ends.
If your current one wasn't already better...Yeah, I know, sketchy as sht right?
somehow, have not damaged a single thread when taking these forsaken things out so far..alu/steel don't play well together. Real troubles on removal in these new long life applications (yr'n a half to over 50K mi). Had some come in w/"life time". No fun...
