1L07 Update. Couldn't find anything wrong with the cryomodule. The removed JT stem assembly looked perfect. I went ahead and replaced it anyway. Reinstalled the actuator and set seating force & LVDT. Closed JT to verify No leak through. Helium circuit continues to hold 8psi. Primary supply ball valve was open. Also verified no helium was in the insulating vacuum while the circuit was at 8psi. Minimum detectable leak 1e-9.
