Squeaking Sound Coming from 225 /6

You know i got to thinking about this thread while im bored at lunch. What if it has nothing to do with oil but a faulty oil sender. And the real problem is a bad alternator. You say the car bogged down and squeaked after revving squeaked again. If the alternators toast and you broke a brush would that not cause squeaking and not running at 14v or so the car wont run the best. Id pull the belts like suggested and see if the squeaking continues. Or could be a water pump bearing if you have just water because remember coolant not only cools the car but lubes the pump. Just a thought.
