A long time ago when I had a beaut 67 Mustang GT conv an old mechanic showed me how to isolate noises. He used a hose and held it near individual items such as power assist unit, alt, compressor, water pump etc to listen to the noises they made. He could also do the same with the valves in each cyl. He was very good to my car and easy on my walley. Wish I still had that beaut.

Looking to find a similar MB master mechanic here in Dayton, Cinci and Col area but no luck yet.
