So this 1997 Nissan Altima came in with a really bad engine noise. At first I thought it was the alternator but it turned out to be something else. You'll have to watch the video to find out what. The purpose of this video is to show a logical method of finding an engine noise like this. If it's a rotational noise like this was, I like to start by removing the drive belts one at a time. If you remove all the drive belts and you still hear the noise, it's something inside the engine. Could be the timing belt or chain. Either way, you're going to have to dig deeper if removing the belts doesn't reveal the source of the noise. Below is a link to a video I did on finding noises that may also help you. Along with an article I wrote about the same topic. So if you have an engine noise you can use that information to help you find the source.
