Snapped Spark Plug :S

[jonnyRT]

my pugs were so old that one has just snapped and left the thread inside the plug hole, how would you get this out?

this must have happend before seems like a right nightmare to get out! must be some way of doing this

HELP!

Can be a bit of a pain to get out, worst case is your taking the head off.

I'd douse it in WD40, get out your Torx sockets, find one that fits in the hole tightly, then go up a size (Should be about T50) then bash this on STRAIGHT with a hammer & an extension, try to undo it like that.

I take it you can see into the cylinder? as in the electrode bit has come out, the white bit?

Cheers, yep i tried that today and it will not move one bit, had my mate (mechanic) whos done it before to try and he couldnt budge it either!

iv sprayed a mass load of wd40 onto and around it so will try again tomorrow fingers crossed other wise it getting drilled out

and yes you can see into the cylinder , only bit left is the thread :S

WD40 is a water dispersal agent no good for this job.
Try some Plus Gas dismantling fluid and an easy-out.

I have managed to remove this part of the plug before using a Snap-on extractor set i have, it looks like this - http://buy1.snapon.com/catalog/item...&group_ID=1254&store=snapon-store&dir=catalog

You usually use the corresponding drill bit, then hammer in the extractor tool and use the extractor nut to turn out the broken screw thread.

You could try using a cheap set of easy outs like this - http://www.toolcrew.co.uk/catalogue...722&pTitle=Screw+Extractor+Set+5pc+Helix+Type

But in my experience if you do not go big enough with the extractor they usually break in the hole and cause even more problems.

Awesome! cheers for the advice im trying to find someone local with some extractor tools like those , also never new about oil like that thanks m8 nice one

tomorrow will be a long day with this i think .......

Whatever tool you use to extract it, cover it in Vaseline or grease to catch any odd bits of metal and prevent them from falling into the cylinder.
