swoosh sound at shutdown

[Hendchris]

I consistantly hear a swooshing noise "air pressure" at shut down from my motor . i have checked my head tightness and fuel lines and i don't seen to be having a tuning problem. Can anyone shed some light on this for me. Thanks fellas

Well I have heard a "ping" and a "gurgle" before but never a swoosh sound that I'm aware of........
Does the engine overheat or have oil all over it after running?
