I have a 2002 Chevrolet

There are several other ways water can get into the oil, you can have a leaking intake manifold, or if the car over heated you can actually have a cracked block.
Can you give some specifics as to what symptoms occurred prior to finding the water in the oil?
Do you live in a cold weather region? If so, did you make sure to "winterize" your cooling system before the first freeze? If you did not you may have some serious issues. WHen the water freezes it can be brutal. Your engine has "freeze" plugs that are actually designed to blow out in the event of freezing weather but I have personally lost an engine block due to freezing weather.
Let me know some of the specifics and I can probably give you a much better idea of what might be the problem.
