I was just going through this post and realized that my Elantra'05 has same issues. My car eats up a lot of coolant and engine has lots of dried coolant chips on it. But never had any other issues with this thing still goin on with my car.
Please update once you figure out wat is goin on, now I am planning to check my car as well.
Also that now I am goin to do wat ken99 said and wash my engine and check the leaks, I have a question is it ok to wash my engine with all electrical system bare and openly working?
