What Does This Sound Like? Help!

I just bought a car last night for 00. It's a '91 Honda Accord LX Sedan. I owned the exact same model for 2 years and it was great.

While driving it home after buying it, there was a small bang and black smoke came from the engine. The engine will turn back on, but it rattles and I don't want to try and drive it. I noticed that right before this happened the oil light flickered and I checked the oil and it was gone. We put oil into the car before we took it, so I'm assuming it has to do with oil. Maybe a gasket blew off the oil pump?

Would anyone know what this could possibly be and what some price ranges are to fix this kind of thing? Don't add in labor, I can get the labor for free. I mainly just need to know prices for parts.

Thanks! Either post here or message me. :-]

P.S. Please don't ask if I checked the engine before I bought the car. I'm not a dumb bitch and my dad, a car guy, was with me when I looked at it.
