hi i have a 2000 saab 9-3 B205r 8 vin k. when i was driving my car the other day the oil light came up and then the triangel waning light came on. i pulled over immediately and shut the car off i checked the oil it was fine so i drove it the 2 blocks home and parked it. now i went to start it up today and it puffed white smoke and had a faint smell of antifreeze from under the hood wen i opened it. i was woneding if the head gasket might have went out or what? the car only has 113000 miles on it.
