The bolt is just a cam cover bolt, it won't have any pressure behind it, just leak. You could clean the area with some petrol to remove the oil and glue the bolt and rubber back in with some Silastic or such. This will stop the leak to get you back home.
The water leak can be found by filling the radiator while cold, then running it till the pressure is up and the fans start, with the hood up. This should start the leak, so you can see where it comes from.
