1. A tool configured to be coupled to a distal end of a packoff, the tool comprising:
a first tube;
a flow tube with an upper face and a lower face, wherein the flow tube is configured to receive a wireline run through the flow tube and an annulus is created between an inner diameter of the flow tube and an outer diameter of the wireline;
an injection valve positioned downhole from the lower face of the flow tube, the injection valve being configured to allow sealing fluid to be injected into the lower face of the flow tube, wherein well pressure causes the sealing fluid to travel up hole within the annulus, wherein the sealing fluid creates a fluid seal between the wireline and the flow tube;
a return valve positioned uphole from the upper face of the flow tube, wherein the return valve is configured to remove the sealing fluid from the tool below the packoff.
