Could be a number of things given your descriptions. Could be internal engine failure ex. spun a rod bearing or main, could be timing chain guides, could be water pump, power steering, alternator bearings gone or starting to go. Best advise. Don’t beat on it until the problem is fixed. Doing so is going to cause more problems or damage in the long run. ---
