Evening all used this site for years looking for advice just never thought of joining it. I own a z22se vectra c for 3 years now it does 25 mpg and with rising fuel costs I have no plans of changing it I did the timing chain myself and have a good knowledge of cars so could be a bit of help to anyone in the future and look forward to help of some ov the Vauxhall boffins (lol) I've seen on here over the years
