Just like to say what a top fella Benny is, my 2.2 is a late 01 model (Jul 2001) and had the small oilway fitted. Benny did a very professional job, was very knowledgeable about all things Vauxhall and my engine is quieter to boot, worth the drive up from South Wales for sure.
If you have any doubt about your chain at all, get it sorted for peace of mind. If you want it done by an honest good bloke go to Benny to have it done.
Cheers
