water loss on a vectra?

Yes, if you are losing a lot of water and can find no leaks then I am pretty sure its the head gasket. As I say, a compression check of your cylinders should confirm it. Maybe ask a garage to do this check for you, I can't imagine that it should cost much. Replacing the head gasket on the other hand might be !

Sorry for the bad news.

Could be that your head gasket has gone and water is leaking into the combustion chamber. Not sure how to confirm this other than to do a compression check. Does your exhaust output look normal i.e. no smoke or water vapour?
