Having experienced this on several older cars, it's usually an engine oil seal that's gone bad. It's an age/time related issue. It's a rather expensive repair, but worth having it done if you intend to keep the car.
Even if you don't intend to keep the car, it will be tough to sell if it is hemorrhaging oil...
