They didn't do any further tests, they just said leave it and drive it until it dies, and I agreed. It runs right now, just overheats if driven hard or if the outside temp is high or if the A/C is on. For the price of a motor swap or rebuild, I picked up the DA...

Replacing the head on any car isn't a lot of fun, which is why I'm also not sure if I want to rebuild this motor or pick up a used one. If I tear it apart to do the head, I am going to end up doing a lot of other stuff like pistons, cams, port/polish, etc... which will actually cost me more in the long run... Tempting to drop a SR20DET in there, but everyone is doing that...
