I have a 1997 Saturn SC2. It has over 260,000 miles on it. I just heard a metallic crack or snap sound, and the spedometer stopped working, a the oil drained out of the engine. There is a puddle of black engine oil under the car right now. The clutch (it's a manual transmission) also feels strange, like metal-on-metal grinding when I shift. If I tried to drive it right now there is no telling how far I would get. I won't go anywhere by to a mechanic... buuuut, it's Christmas Eve and I'm at may folk's place 150 miles from home.
