Hello, the most important thing is for a technician to be able to experience your concern when it's happening, so that the root cause of the concern can be identified. It's not about being believed, it's about finding out what is happening while the problem is occurring. Indeed, it may be necessary too lave the vehicle overnight so that a cold start can be done by the technician.
It's difficult for me to guess what's going on from here because I can't experience the noise first hand. I can offer guesses, but those really do not do much because I may be way off from what the noise is.
Seek guidance at a local shop near you.
