you shoulb be able to get the sheared bolt out without to many problems see if it will tap round with a little punch and hammer shouldnt be tight

I had something in the distant past where that had happened (Ford maybe).  Didn't find out till I replaced the rocker gasket, by which time I'd done 20k in it.  Never did bother doing anything about it

Unless it's somehow stuck in the threads then the remains of the bolt should just be sat there and farily easy to move.  Try tapping it round with a punch as suggested because drilling it to use a stuf extractor could drive it further into the head.

thanks for the advice got it out with the extractor well brothe dib it for me  :D
could anyone tell me if them bolt have a torque setting to tighten the to

[TDi90]

yes they do!!
and it is IMPORTANT you read the haynes manual and do them in the right order, and do them to required torques because IIRC they are whats known as "elastic" bolts or something... they stretch basically.
