I think you've got that mixed up. The leakdown test pressurizes the cylinder. With valves supposedly closed. If air is leaking, it's generally going to come out in one of three spots; exhaust, intake, or down past the rings. If it goes down past the rings, think about where that air pressure is going to go to excape....

Bad intake valve....you'll hear air in the intake. Bad exhaust valve...air in exhaust. He did not experience either of these. Obviously there are other places that air could leak out, for example a blown head gasket.
