No, all the hoses are hot. Now, the top rad hose is hard as a rock. The lower hose is hot, but has a spring in it, so I can't really tell if it's super hard or not.

Me too. I had the same thing happen in my commuter car (a Nissan) and replacing the head gasket fixed it right away. But I needed that car to get to and from work and it cost me $1200 to get the job done...I can't afford that again so I'm being critical and don't want to do it myself if I don't have to.

The reason I did the exhaust gases test (block test) 4 times is because I was very surprised that #1 came up negative. I fully expected it to show a leak from a cylinder into the coolant jacket at the filler neck (test #1). So I did a control
test by sucking exhaust directly from the tailpipe which DID turn yellow. Then I tested the overflow bottle where the air from the radiator was going (test #2), that was negative, and another test (#3) at the filler neck, and yet another test (#4) at the overflow. I didn't even get a whisper of exhaust gas.
