My neighbor (ex mechanic) has the tool and already tried the pressure test on the coolant reservoir. The gauge barely moved and the pressure stabilized, which would typically loose pressure, if there was a leak. He used his air compressor to blow out the coolant that was setting around around the knock sensor area. He kept the pressure on for 15 min. and the coolant was not leaking anywhere. :/

Just tossing a thought your way. But possibly a hairline crack or head gasket leak??? it can hold pressure until its at temperature then it could just leak... like a trickle. enough to be annoying. Just a thought...with everything you've done to determine there isn't a leak at the thermostat housing or surrounding hoses and clamps...if there is still a leak...then you're left with heads and gaskets. Especially if its holding pressure when you test it. Cold tested engines aren't the same as an engine at running temperature. You might have a small window opportunity to get a visual on a hairline gasket leak???? Just saying. You've covered all the bases on the thermostat and surrounding symptoms...it doesn't leave much more to look at.

I checked with my buddy and asked if we can do another test, but this time, I will drive the car around a bit and then keep the car on his garage, while we look over.
At first, he thought it was a freeze plug, which is located in front of the knock sensor. There was a puddle of coolant in the freeze plug and knock sensor areas. Maybe with me getting the car up to temp, the coolant will start leaking and we can pinpoint it!
I am praying it's not a cracked head!!!!!

UPDATE:
Well, after my neighbor (ex mechanic) did a warm pressure test on my Mustang, it turns out it is an external head gasket leak. It is slow leak and is leaking out into the valley of the engine, therefore no internal engine issues will occur. Unfortunately, the issue will continue to get worse overtime and start leaking more, however as long as the leak is slow, I don't have to get it fixed immediately.

Ack, sorry for not replying to your question to me sooner (way back on Nov 7thish). The leak on my daughters Escape was at the connection between the Hose and thermostat housing. The clamp wasn't applying enough pressure so when things started to cool down, water would seep out from between the nipple and the hose. Once I put a worm clamp on there, I was able to properly seal it.
That sucks about the head gasket.
Maybe now it's time consider performance heads? Since you have to do the one side, may as well do both and get some performance if you have the money?

I'm assuming you'll need to get a dyno tune after these as well.
