Hi A friend has just bought an R reg 1.8 Vectra. It has had a replacement engine fitted at some time. Some of the odds and ends around the engine bay don't seem to fit properly and I'm thinking the replacement engine is actually a 1.6. Anyone know a quick way of telling the difference between the two? Alternatively, is there a website listing Vauxhall engine numbers and their meaning? (I couldn't find one with Google). TIA, Chris.
