Could be head gasket, intake gasket, cracked head/block, freeze plug... check the oil for cross-contamination, same for radiator fluid. There's a cheap and simple product called "Block Tester" sold at Napa that will check for combustion gases in the radiator fluid that's often associated with head gasket issues. (http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=BK_7001006_0361073538) however, you should still have a good mechanic look it over, this is the sort of problem that can go bad quickly if you continue driving, especially in freezing weather.
When you remove your oil filler cap do you find a white muck? Blown head gasket. Any puddles under the car when you park it? All hoses good and tight, not leaking? start there.
