Spark Plug Removal

[Yoshi]

OK, am being a wimp, but i cant get the first one i try out!!! lol, it just wont undo!

[gnasha]

try doing it up very slightly then undoing it keep socket as straight as poss so not to snap plug and put some muscle into it

[Yoshi]

Tried that, got nothing!

Need to get this done tomorrow as it wont start now and i have got a feeling its something to do with plugs/leads etc..... lol

Before you get too worried about it being the plugs pull of a lead and see if you get spark between lead and clean corner of the block. Least that way you can rule out other problems first. However if you've been trying to start it for a long time they may need a clean up anyway, mine wouldn't start cause they were so gunked up!

Then make sure you have the right size socket, with thin walls. (my socket got wedged between the spark and cylinder head which doesn't help). And a decent rachet.

Otherwise don't know what else to suggest

What size socket should i get though?

ATM i am using one of them all in one jobbies with a handle, but i just cant get the grip on it i would with a socket! 

There is so many different sockets on ebay, i dont know which one to buy! lol

Hi mate, try this.  Soak them in WD40 then put it all back together and go for a run, get the block and heads nice and hot then with your asbestos fingers try to budge the spark plug straight away.

the ali in the head expands twice as much as the steel in the plug ;) so in this horrid cold weather it'l be tight as a tight thing now.

They are "normal" spark plugs so any socket set would have the right one in it (it's the bigger one not the small one which is 14mm IIRC).

Aye thats the one mate, had an inckling it was 14mm but wasnt 100%!

Reckon it will be ok with getting a socket on it, its just the tool i have now you just cant get a decent grip!

P.s. cant run it to get it warm cos it wont start (read post 1!!!) lol

I could be wrong but i think you'll find spark plugs in a v8 are 21mm!

I have recently changed my plugs, abit of a pain to get no 2 & 4 Out. I used a spark plug remover tool from halfords and alot of strength.

I've just checked my socket. I used a 13/16 plug socket on 3/8ths drive. That would be slightly smaller than a 21 i recon.

14mm refers to the thread size!
