What are you using to try and break it free with?

 

A breaker bar and enough extensions to get away from the wiring. I also have added a piece of pipe, but that's how I stripped the spark plug nut when it let go. I also used my racket..

 

You need a one piece extension. You are losing impact force with the extension joints. A 1/2" would be better with a 2 to 3 foot breaker bar. You are twisting and flexing with the one you have. I believe it would have been out by now with 1/2" tools.

 

Those extensions are probably flexing quite a bit on you, and that’s a pretty short breaker - it’s also a weak point. Any chance of borrowing a 1/2” drive set up? And a long breaker bar, 24” at least? Even if not, as long as the socket isn’t stripping anymore, it might work with a pipe. An impact if possible would be nice too.

It was mentioned earlier, but I’ve driven smaller sockets/wrench’s on to frozen / stripped bolts, as in socket is just slightly too small to fit and drive it on with hammer. Depending on the socket it may split the socket, so when you’re pulling / turning, be careful if it lets go, don’t let your arms, knuckles etc hit things and split something open… best to get tension on the breaker bar, then start tapping it with a hammer to shock it.

My advice might shear, or break the plug, it may also pull out the threads on the insert, or shear the 3/8 extension. I’ve also broken breaker bars, usually at the pivot point when it spreads, or shearing them. When you do break it free, stop and start soaking it again with penetrating oil as you remove it. Give it a min to soak in a bit.

Aerokroil is good stuff if you give it time. I’ve used it many time to free up parts.

Again, if you have a big / good enough breaker bar and extension, it will just shear that little plug if it’s corroded bad enough.

Hope this helps, good luck with it.

 

Using the 1/2 inch drive is how the spark plug nut was stripped in the first place. I used my Neighbor's long extention and breaker bar . We were really reefing on the plug, tried to get a better position, it slipped then no more bite. I'm going into town tomorrow, so I'll get a longer half inch breaker bar, and longer extention also 1/2 inch. I'll need to reshim my 13/16 socket again with 100 grit sandpaper which is how I got it to bite today.
Breaking off the top of the plug is the last option as long as there is hope.. We're having an extreme wind day,,so i'm done right now.. I know this should have been over with, but these spark plugs are welded in place. Like I said in 45 years I've never had this problem. Spark plugs usually fall out first in my experience.

 

You need a good black impact socket that won't expand when stressed.

 

This is what I bought yesterday. Now I guess I need the driver.

 

See if you can get one in 1/2 inch. You will twist off the 1/2 to 3/8 adapter. I've twisted a lot of them off. Maybe a black one, if you can find it, will hold up, but every joint will cause you rigidity and torque.

You need to be aligned as straight and square as possible with the plug, and try not to get out of line with it when trying to break it loose.

 

I'll try for new tools tomorrow when I head for the big city. . . Port Angeles.

 

Dynamite works every time! I think the threads were bunged previously, so I'll try to clean them up later. I can only take one victory a day.

Yes, I used anti-seize!

 

Make sure you use antiseize on the new plugs

 

Yes! Two tubes and a pound of lard should just about do it.

 

Really glad you got it, I thought I was going to have to send you this!

 

Thank you! I was almost up to step #4. I think the previous owners knew of cylinder #5 issues, but failed to relay the message. I'm not sure the plug is fully seated, but I'll play with it this weekend to be sure it's in. I ran the truck for nearly an hour after getting the new plug in just because gas is so cheap. Thankfully it doesn't run on milk. I swear the farmers cows are rolling in Mercedes Benz's and have gold capped teeth.

 

this, I had an old 1/2 inch ratchet which is rugged and been through things and a nice "newer" one but also that size, even had more leverage. The "feel" of comfort you hope for to not break things was lost on the modern one quick but it went furhter with the older one. It did get "uncomfortable" but at that point I figured if Im going to find which one is the weaker link id use the one that made it further and I was successful. Stupid reach and angle tho but thats just me being small and the engine being longggggg
