Its 100% rod bearing. Especially if you took the pan off and it was loose and tightening a blown bearing WILL NOT HELP YOU. when a bearing goes the rod walks around the crank and will absolutely damage a motor to the point where the whole bottom end needs to be rebuilt especially if he was driving around trying to "diagnose" the problem. Tightening a loose rod bolt will do nothing but make the problem worse! DO NOT start the car again even though the bottom end is prolly shot by now. It will be much cheaper to buy a new motor then to pay a machine shop to fix the crank replace the bearings and while your in there you might as well do new rings/pistons especially since u might have damaged the cyl walls. Sorry to hear about your misfortune weve all been there! but next time you hear a knock turn motor off immediatly to save yourself a grand or so possibly.
