Cheers for all of the comments.
I think I might be sticking around now, just bought a Y reg 2.2 Vectra Estate with 'engine issues' so I guess you'll gt pretty sick of me bugging you all for spare parts and advice!
PS. Anyone in the NE who is a wizard with this engine give me a shout. I have an almost endless supply of tea/coffee/biscuits and a nice big drive to do diagnosis on!!
