It is hard to say. If it needs main or rod bearings, the crank needs to come out to be cut or replaced. Basically a complete engine tear down. If that is the case, I would est around 3000.00. Can you describe what you hear, when you hear it, and what the oil pressure looks like?
Also, there are no lifter bearings. There are cam bearings.
