I am going to need a lot more information in order to set you on the right track.

Is the car turbo, or N/A

What year is the 13b (SA, FC, FD, or Cosmos)

What color is the smoke coming out?

How many miles are on the motor

Have you done a compression check

Do you have bubbles coming through the coolant system

A basic diagnosis from what you are talking about seems to imply that you have blown a coolant o-ring between the plate and rotor housing. In which case the repair is not going to be cheap.
