This may sound dumb!
Stick a piece of 3-4 foot long heater hose (Really any hose) Maybe 3/8 or larger diameter---IN YOUR EAR. Use the other end like a stethoscope.
Takes a few minutes to get accustomed to sounds, even create a vacuum leak, just so you know what EXACTLY, you are listening for!
You can buy me lunch later!
Let me know how it goes!
