If you have low oil pressure along with this noise, you can bet it's telling you the bearings are on the way out. There's no quick fix for it, it'll need a bottom-end rebuild.
Don't go by the reading on your stock oil pressure gauge either. It's basically more of an idiot light with a needle than a real gauge, just telling you if you have oil pressure or not but not telling you what the oil pressure actually is. You can get a mechanical gauge pretty cheaply that you can install in a relatively short time that will give you a more accurate picture of what your oil pressure is doing.
