mine does this too and its always done it, i thought it was some kind of relief valve like on the old 80`s mk2 ford escorts (UK fords) they had a gulp valve strapped to the inner wing which flooded the motor with air when switched off to prevent it running on (pre ignition) and the sound is very similar to these old fords.
