ok. gone to take the head off of my 2wd cossie and i cant get one of the bolts out becuase the head is chewed... u can just get a bit in there but when u turn it it just jumps up.

any ideas as the car has been off the road for 2 weeks aready

cheers

 

need more explanation !?

are u stuck on 1 bolt or can't get any out?

how u mean the heads chewed u mean knackere ? that shouldn't stop the bolts from coming out

 

sorry mate, have got all the bolts out excapt one , at the back on the exhaust side, they are round on the head and the inside is torx shape, but by the looks of things someone has tried to get it out b4 and failed and now the torx bit doesnt fit properly

 

What about grips or something similar? Or try tapping the torx bit in and then un-doing it, needs must really, just be careful and im sure you will get it out.

 

cant get anything around it as it is recessed into the head

 

Ah, i see

Have you tried tapping in the next size up torx then to try and get a bite on it?

 

the next size up is far to big

i needs a t55 at the mo ( which is about the same as a 10mm allen key, the t60 is about the same as a 12mm allen key )

 

hmmmm, what about drinlling down the centre of the head of the bolt, then you could pull the head over the bolt shaft and remove that after? You'll need a fucking good drill bit though

 

hmmm... you say a torx bit,, but it isnt actually a torx bit at all, it looks like one , but isnt, its aspecial M12 12point drive bit , used by ford VW and a few others for suposed "main delaer" type operations..

if you have been using a torx bit, that may be why its slipped and chewed up, the proper bit would never come out...

the one on the right

 

They do look similar, torx have a lot deeper teeth though don't they. I'm surprised a torx would even fit that well Torx are only six point arent they?

Is there any possibilty hes got some after market bolts fitted that are torx?

 

you have a good point, they are 12 point. but i have never had a problem using the torx ( 6point i think they are ) bits. i tried to get hold of a 12point type last time i did the head bolts on a cossie but cudnt get hold of one

 

What a shitter

Well first things first i'd get the correct bit and you might get lucky and just be able to tweak the bolt undone, certainly worth a try and your going to want it when you re-fit the head anyway, certainly worth a try you have nothing to lose
