Hold the phone. I'm only going by what you've posted so far. If the oil pressure is good, it is doubtful a bearing has "spun", meaning it is destroyed. One of those will be the first thing to go when serious damage occurs. With good oil pressure, most likely you are not hearing a connecting rod knock. That is pretty loud, and people in the parking lot will run to get out of your way when they hear you coming. If you're hearing a light ticking up higher in the engine, that is likely the valve lifters that have bled down from lack of oil. That is relatively minor and will go away on its own. At the mileage you listed, it's not uncommon for a lifter to be reluctant to pump up with oil right away. I had an old car that had one lifter that always took at least 30 miles to quiet down after every oil change, then it was fine until the next oil change.
Before we assume you need a different engine or a rebuild, have a mechanic listen to any noises that are still there. A collapsed lifter sounds a whole lot different than a rod knock.
Sorry to leave you hanging for so long. I'm fighting a dying computer that is on its last legs.
