    How is your coolant level? Does it drop?

    It potentially has a bad head gasket, which is a known problem in high mileage gen 3 Prius cars

    Super low oil level will sometimes create symptoms like this... But seeing as you've done so much already to address this problem, I highly doubt you've over-looked being a couple quarts low on oil. :)
