Decided to do some head gasket tests.
I don't see any antifreeze leaks.
I checked the oil for antifreeze. It looks normal, not gray.
I started it up with the radiator cap off to check for bubbling. I didn't see any. The fluid level was way down from overheating, but started rising fast. So I opened both bleeders. The fluid level went down. After about a minute antifreeze was coming out the bleeder by the water pump so I closed that one, but none from the bleeder on the other side. The fluid level camp up fast so I shut it off. It dropped down 8-9" right away. I started it back up and within a minute it came right up again and overflowed. The one bleeder was still open. I never saw any bubbling.
