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.

Need more help!. I put in a new motor (same) and trans(malibu,I believe ,which I was told was compatible) the trans has a dif shifter box on top(2 wire harness spots)(original has 1) I tried just switching the box to fit my 1 wire harness! The wheels are still spinning free! What are my options
