Funny how I was just starting a thermostat thread and have been discussing the fact that many of the cold weather CCV issues may be caused by engines running too cold!

My suggestion is to have the shop perform a compression test and cylinder leakage test on your motor. This way you will have an idea if the engine is really damaged. Or if the engine is still running and not sucking oil into the intake, drive the car for a bit to see if the smoke clears up.

Hydrolocking an engine is not a good thing, but you may have gotten lucky??? and only filled your exhaust with oil that needs to burn out.

If you think the engine is salvageable then you need to replace the thermostat and make sure the engine is running at 95C and replace the CCV and make sure the dipstick dual walled drain is clear.
