If the light is on, the oil pressure is extremely low and causing the noise. It may have damaged a rod or main bearing at this point. To confirm oil pressure, rent a mechanical gauge at a parts store. It will screw into where the electric oil sending unit is located. From that you will know how much pressure you really have. As for what caused it, make sure the oil filter you have is correct.
