This might be way off but it is an easy check.
During the Summer I experienced a similar intermitent noise coming from my Engine compartment.
I actually thought I had valve issues or worse.
Checking everything showed that my engine was OK.
What I finally found was that my Vacuum hose going to the Booster was collapsing under high Vacuum causing a gasping sound which from the drivers seat actually sounded as a mechanical error.
I just disconnected the hose and drove the car for a short trip ( be ware of very bad braking performance)
New hose on and everything sounded normal again.
