Not exactly. The new tight-fitting cap is there to stay, but they may re-open the valves which are presently preventing oil from escaping if the well is determined to be insufficiently sound. In that case, the new cap will still allow them to collect all the oil, preventing any from leaking. That may take a week or so until they can get more collection ships, though.
