I wish I could say with 100% certainty, but without being there to hear it, I could be wrong. However, based on what you said, it sounds like a bearing in the engine has failed. If that is the case, you will be either repair your engine or looking for another one.
If you take it to a mechanic, they should be able to tell you in 2 seconds if it is a bearing noise.
