Well, another weekend and not much time to work on the leaks, but after replacing the water neck with the Ford part, and putting everything back together, I had a hunch my attempt at tapping the threads was not going to end well. When I was tapping the threads for the temp sensor, it just didn't go cleanly. The sensor threaded in, but it didn't feel smooth. As suspected, it leaked at the sensor. So, I get to do it again. New water neck will be here in a few days, but I'm not going to tap this one. I'm going to install the sensor in the heater port on the manifold. I will get this solved eventually, but at least when I started the car today, it fired right up and idled much better than last time. I'm pretty sure I resolved the oil leak on the valve cover. It looked like the cover wasn't seated fully and was hitting one of the throttle bodies that needed a small amount of clearance work. I hope that by the end of next weekend, I'm able to drive the car again.
