Hello and welcome to JustAnswer!

The noise is more likely coming from an engine accessory rather than the engine itself. I would expect the noise to be coming from the alternator, power steering pump, a/c compressor, water pump, tensioner or idler, etc.

If the noise gets worse when turning then it's most likely the power steering pump, either from a pump failure or low fluid.

A mechanic's stethoscope can be used to listen to each component, you can also remove the belt and spin each component by hand to feel for play, roughness, and listen for noise.
