Sounds to me like you have a current draw that is killing the battery. Look for the obvious, like a glove box lamp staying on, radio, other lamps. Anyhing plugged into a power outlet. If all those check ok, then further diagnosis will be needed to find the draw. A multi-meter can be set in series between the negative battery cable and negative batter terminal to see the amount of current being drawn. On yours, I would expect to see less than
20mA, probably closer to 0. As far as the noise, hard to tell from here, is there oil in the engine?
