Had the same noise, sounds like squeal. Then it's your AOS going. What is happening is the AOS is sucking air around the front crankshaft seal. I also checked and tried to remove the oil filler cap when mine was squealing and could not. Replaced the AOS and end of problem. And the engine never blew smoke when it was failing.
