    I have tried this as well. (checking for the head gasket issue)

    I am going to pull apart the thermostat and do another inspection. I am wondering what is going on at the water pump. What kind of failures that may have. I added a couple of pics cause this is going so well. Who knows I may have those hoses backwards, even though I have inspected that video 50 times!! I have the overfill bottle hose at the front of the water pump. I just found this pic of my thermostat. It is not closed. I wonder if this is also hurting the way it opens. I may of found something here!!!

    UPDATE: More of the same. But the new one that I installed was rebuilt. I know that because it has the silver ring around it. (pic added showing the ring and new connector) A tell tale that it has been split and replaced at sometime. This rebuild kit is for the earlier models. Not mine so back to ebay to get another oem that works. I tested the old one on my stove with a pot of water and a thermometer and it opens once and a while. Not all the time. So the old one is junk. I ordered a new one and I am awaiting deliver for the install.

    Edit: I have since learned about the possibility of an air lock causing the pump to not work. I am installing the pump again, bleeding the system to the best of my ability by pumping the vertical hose from the top of the water pump housing to the cylinder head, till I get the air to escape back to the overfill bottle. I can tell you that the last time out I never did have to fill the overflow tank one bit. This may be evidence that I did have an air lock.

    Air lock was not the issue.
    This turned out to be a blown head gasket. This was caused by the ride plate issue. By the time I was able to diagnosis the ride plate the head gasket blew.
    Thanks to all the assisted me!
