BIG Problems...I think

[radarwhiz]

At some piont today my engine ran out of oil...very bad I know. This morning began making a slight tapping sound (like maybe a stuck valve) which I have known before to be attributed to low oil. I stopped and checked to oil and it was fine (just recently got the oil changed). Some time after that point, apparently all the oil leaked out. Driving home and I started hear a bad rattle from the engine so I stopped and shut it off. Only then did the oil light come on and of course it was bone dry. I figure I'm pretty much f***ed cause it sounds awful. But I hitched a ride and got oil and filled it up and when I started it, it sounded fine. So I continued home. Just as I got into town (15 min later) the noise started again and much worse this time (sounds worse than a diesel on a cold morning). I'm guessing this is really bad, I'm wondering if anyone here might have any idea how bad.
