Head gasket is leaking into the cylinder but not into the oil. No so unusual. You can save money now by parking it until repaired. Good luck!

It could be a number of things but more than likely just one of the gaskets. If you haven't driven it while it was overheating it shouldn't be warped, just needing new gaskets and a good clean-up.
