Most likely it is the rod bearings or the mains on the crank. I would pull the oil pan and pull your one and two rod caps and look at your bearings. You shold be able to tell if they are bad or not. If bad they will have groves in them or be burnt looking or even be a copper color. On the mains I would bust on cap loose and get some placty gauge from an auto parts store. then slide a little piece of the gauge between the bearing and the crank journal and retorque the cap and then break it loose again and pull the gauge out and see what measurement and compare with tsrm...
