ughh. Finally proved I had a blown headgasket. I was trying to track it down when I started this whole thing. But I thought it was because the fan wasn't working right. it was only getting to 185, so no damage. But when I got her running, coolant was coming out the down pipe. So, I have most of it back together. I never saw a gasket that proved to me it was blown, but the radiator was pressurizing after 30 seconds of running. Just need to spend about 1.5 hrs of work tomorrow and she should be running, and idling fine.
