Default Can't get spark plugs out.

They are in there, the other owner replaced them a few times over a 6yr. period, but he never used anti-seize, i aplied some force (as must as i'm willing to chance) with no luck on #s 1 & 3, how can i get them out without major issues, i'm sure they are fine, but just wanted to inspect them, what can i do?? "HELP"

Will it hurt trying a 1/2 drive ratchet?

hope you have another means of transportation, yeah, if your having to use a 1/2 inch they were overtorqued, try the penatrating oil first. If that doesn't work, bite the bullet and torque em off, the worst thing that can happen is you have to pull the heads off...

use the pb and make sure that one hand is supporting the ratchet head while the other is on the handle.less chance of breaking it.

I almost started to cry from laughing at that. LOL. No but seriously.

They will come out. I The insert might come with it but a shop can helicoil new threads in if they do tear out. But they, hopefully, are not going to do that.

Also try to tighten them just a smidge. I mean dont really tighten them more just apply alittle torque that way to maybe break up some of what ever is holding them in there. Like I said before though let some Pb blaster soak on them for alittle.

Even though its a last resort, have you tried a breaker bar? I'm doing plugs and wires now as well on what I believe to be 53,000 original plugs and am running into the same problem. 1/2" ratchet did not work for me either. Just take the bar and go REAL easy with them to break them free and use the ratchet the rest of the way. Good luck.

This is what I was gonna say. I used a hollow metal pipe and slid it on my ratchet. Just make sure the socket is on the plug good so you dont break the porcelain. But also give it some wd 40 or other p.o. before you get started

I got one to come out, just a 1/2 rachet, now to get some ANTI-SEIZE, thats what keeps this from happening, so there is hope.

Now the big Q? Should i go with some NGK TR55s, or will these Bosch Platinums be good (thats whats in there), I personally do not like Bosch, but that was in my older Mopars lol, NGKs ran the best, i'm getting alittle "peppering" on these Bosch's, so i'm sure thats detination, might be too hot a plug. Whatcha guys think?
