Let's see, he was tapping threads into the towers to put threaded plugs in is how I read it. That would mean the threaded piece is larger than the oil port, and would definitely be wedged somewhere in the tower. With constant oil pressure pushing it upward, if it did dislodge it would go back up the tower and up against a threaded plug. If you notice those oil ports, they are larger or they come out of the top of the tower, than where they enter the lifter bore. So it's basically got nowhere to go.
