Frozen Engine

Hi Folks---
This weather is surely taking its toll both on people & cars my 5 is garaged and in a timber built one at that but with all the fuss of trying to get it finished i forgot to drain the water and put in antifreeze mix. To my horror i have just discovered that my rad is frozen solid all pipes work frozen to twas not until i had the car started that i discovered the cause so i switched her off immediatly.
Question is now???? did i do any damage to the block. Today i spent about 2 hrs de--frosting it with hot water on all the rad pipes & got all the water out of the rad added some coolent mix started it and everything seemed fine till i discovered a leak at the bulkhead end of the engine near the water thermosenser its spews it out when i rev the engine. HELP HELP---Will i have to take the engine out to get at this peoblem . And i havent even taking the car out yet as i dont have it long-----any ideas gratefully received
