In one aspect, apparatus and methods for directing material penetrating a leaking nozzle repair shield seal to a predetermined indication point such that a user viewing such indication point is alerted to the leaking seal condition is provided. In one aspect of the present invention, a channel having six distinct sections directs the material to the indication point. These six channel sections include two annular sections extending about the periphery of a main cylindrical section and an inwardly facing surface of a flange of the nozzle repair shield. These six channel sections further include a reservoir and interconnecting channel sections. Also, a sleeve for encircling the outwardly facing surface of the main cylindrical section of the nozzle repair shield is provided and the indication point may be provided in the form of a reservoir.
