I have just put the Astra on the drive as my girlfriend has just got home from work and when I started it up I heard a slight rattle from the engine, it went off very quick and all was normal again notsure.gif . I hope it's not the cam chain dunno.. . I will also check the oil once it's cooled down. It's never rattled before at all, and the car was still warm, so I am not sure what it can be dunno.. . Should I be worried shrug.. chill.gif
