Yep while changing my head gasket they have snapped a bolt off in the head....

What are the implications??

I'm a bit pissed off as its been there a week now! and not going to be ready till Tuesday now,

Sad face indeed!

Oh that's not good, depends where it's snapped, if it's snapped flush to the engine block then it's drill the bolt shaft and helicoil , not easy as they are toughened bolts.
if its sheared not flush then a stud extractor could still save the day. Either way, drilling with the head off the engine with lots of metal swarf is not good with an opened up engine :sad1:
not a job to be rushed

Or there is a process called Spark erode, but that would be engine out, fully stripped down and done that way.. But not sure that method is still used today..

This is making me as snapped as the dam bolt!!


They said its sheered off : (

That's all they said but I'm hoping they do a good job of sorting it out! Can't believe all this after thinking it was a simple coolant leak!

Hopefully they won't get anything in the engine and they give it a good oil change and it comes back all sorted!

I would be happy if they did that and stripped it all down and cleaned it all out! : )

I'm not sure they said they've got all new bolts to put in?

Well some monkey has overtighten it then... I'd be onto VW UK just incase...

I am scepticle though bu knowing delaers they probably tried to use the old ones... either torqued used, or overtightened new.. it wouldn;t just snap.

Probably snapped when it was being removed, nothing you could do about that really.

I'm sure the work will be warranted for a while so I wouldn't worry to much
