This morning, the reservoir is completely full. What's weird, though, is that my upper radiator hose was still collapsed flat. (Returned to normal after opening the cap) If there was a leak somewhere, shouldn't have returned to normal overnight?
your radiator cap is faulty or the line going into the reservoir from the radiator is semi clogged with crap.

at least that is your problem, almost everyone else in this thread has a bad motor.

Ah, ok, thanks. Yeah, I put in some stop leak metal sealer when it started leaking (which turned out not to be a leak, but water pump failure). Guess there's some residual crap in there that I need to flush out.
