A tubing pressure insensitive failsafe wireline retrievable safety valve, borehole system having the valve and method of operation of the valve. The valve includes a tool housing, a flow tube disposed within the tool housing, an actuation piston disposed in the tool housing and operably connected to the flow tube, the actuation piston having an actuation side and a pressure side, and a fluid pathway between a potential leak site for the valve and the pressure side of the piston. A temporary sealing member is in the fluid pathway between the potential leak site and the pressure side of the piston. The method includes disposing the valve at a selected location and removing at least a portion of the temporary sealing member from the fluid pathway after landing the wireline retrievable safety valve at the selected location.
