how do i get the last 2 head bolts out of the centre of a zetec head without twisting and snapping the torx bits? they are incredibly tight!!!

 

decent torx bits shouldn't twist/ burr if they fit snug, and you have enough leverage - shouldn't be a problem.

I often find those cheap ones you get in sets are pants I've got through many of those.

I tend to buy hardened bits for common sizes, so I know they aint going to burr.

 

as above but another tip is to buy a long breaker bar for leverage, far easier to loosen stiff bolts, less likely to round the bolt or socket because you can undo it in 1 attempt as opposed to hitting and thumping your standard ratchet

 

ithought the 2 middle one where suposted to come out first????

 

yip mid 1ns should be first to come out

 

cheers guys, i did contemplate buyin a breaker bar but for some reason i didnt, the bolts under the cams came out ok tho. any advice on building a zvh turbo would be great

 

The Bolts under the cams, Its easy to take the cams out, Then its easy to get to the head bolts

 

well i bought a breaker bar and some new torx bits, i re-tightened the headbolts and sprayed wd40 on the centre 2, they still wont come out! the bolts are starting to round off so i have let be for now. the last thing i wanna do is resort to drilling them out.
