Synopsis: Spark plug socket not getting any purchase on spark plug, though it's the correct size.

Long version:

In the process of swapping my spark plugs and I seem to have run into a bit of a snafu.

I've got everything disconnected just fine and I'm ready to pull the current plugs, only I can't seem to get a bite on my spark plug socket. It's the correct size, as I took the info straight from the guide (13/16), however, when I go to unscrew one, there's no bite.

I've tested the socket on the replacement plugs (NGK BPR7ES) and it works just fine, I just have to work the socket a bit to get the top part of the plug through the insert.

I'm curious as to just how hard I can press down onto the current plugs to get them into the socket. I'd really love to not break one in the process of removing them.

The socket:






Did I just buy the wrong kind of socket? ~_~

 

maybe being that the wrench is crooked and slanted it doesnt fit down the cylinder right and hits the walls not allowing it to seat correctly on the spark plug

 

It's on a swivel joint. Was the only style of plug socket available at the place I picked it up. Didn't think there would be an issue.

Maybe I'll just put everything back together and run to sears or something and see if I can find a better socket.

 

I just use a 21mm extended socket with an extension then use pliars to pull the plug out....i changed mine today

 

 

I don't know about you but my stock plugs were 5/8s that might be your problem And I wouldn't use those NGKs as replacements either

Wrong tool, looks like a 13/16 spark plug tool. That's a great tool for changing plugs on a Z28, not so great for an Evo. You need a 5/8 spark plug socket, ratchet, 6" + extension.

 

You may want to use a torque wrench to torque the plugs to 19 +/-2 ft lbs.

 

the 8's and 9's use different sized sockets.

Bloody hell. Looks like I won't be changing the plugs today.

All the info I read, including the guide, involved the tools I was using...but there was no mention at all of them being specific to VIII's. Oh well, I'm just glad I posted something about it instead of trying to force the **** to work.


Guess I'm going to the dealership tomorrow to see if they have the stock ones ~_~

 

Yup IX plugs are way smaller than 8

 

Other way around

 

Are you sure?
My 8 plugs are 13/16 which use the bigger socket. The other size is 5/8 which is smaller.

 

On a table display full of cheap tools I found a spark plug socket that had instead of the rubber insert, a magnet. The problems with a rubber insert is that when it is new it doesn't hold and when it is old the rubber gets hard. A spark plug socket with a magnet as an insert works a thousand times better. Well, actually, that is an understatement.

 

Take that tool back to K-Mart and get a real socket and ratchet.
