Sorry to hear about that 🙁 , Is the engine giving you signs of the chain giving up? as can be seen by my recent posts, Im starting to really think about getting mine done.
Im on 72K at the moand it grows rapidly by the day.
Cam-belt went on my Astra - £1200, it aint pretty.
Hope you get it sorted and maybe get to see you soon.
Take care cheers..
