If you have loads of noise and oil on the floor a bearing has failed. You will have a car that cannot be driven but not, I believe, a car that has seized in its tracks. It is usual to replace a noisey bearing before it breaks up to prevent the damage it will eventually cause, if you are not concerned as your gerabox is elderly then carry on. Good luck and enjoys your cars last days!
