Hi All
Thanks for all your help. Just thought I'd post an update.
AtomX kindly offered to do the timing chain and auto box, but wasn't available until a couple of weeks later.
Before then I started it up one evening got the dreaded rattle. I drove it home and had lack of power and it was making the dash vibrate.
So I contacted the local VX garage and got it booked in. They replaced the timing chain, balance chain, replaced the oil in the auto box and serviced and re-gassed the air con.
Cost a pretty penny (over 1,100) but all working now. Only thing I noticed is that it seems to have less torque now - it revs up to 3,000 before changing gear.
But aside from that, it is running OK at the moment.
