Could you tell me where you got this done as need the same work done and that is far cheaper than ,most places?
John - I got it done at Eldon Street garage in Preston.
The chap who runs it is a friend of a friend, so I think he gave me a very good price.
That said, I still think they'll be cheaper than most places.
Pretty much any garage should be able to tackle this job - most will have replaced a chain on a Vauxhall at some point.
I should also add that I've had a bit of an issue with surging revs since, I think this is down to the timing not being set-up perfectly...
