Nothing to worry other than having to change your AOS unit ($300 job sadly)

Friend here had the same thing happening to his 986 of the freeway. HUGE puff of smoke, car/engine stalled because of all the oil found its way in the cylinders at once and that doesn't burn too well. Dash lights went on (solid CEL), we all panic, etc etc etc.... same as yours.

If the engine simply stalled slowly and you didn't heard any damage-style noise then the engine is just fine mate.

Hydro-lock, whatever that means, would have "locked" the engine and you would have heard it badly I believe. Possibly wheel locks and all as well......

Wouldn't worry too much. Also, because some oil found its way in the exhaust system, your O2 sensors will be next

Cheap cheap fix
