"Woosh" noise on shutdown, and other engine noises
First, does everyone have that odd, relatively loud "woosh" noise when they turn off the engine? It sounds pneumatic in nature, like a pump or servo of some sort sealing or depressurizing? I should note that I park in a garage, which may amplify it. Definitely more noticeable if you open the driver door or window then kill the ignition.
Second, I don't know if it's the cold, a bad batch of gas, or just normal but the motor seems to make a clack clack clack noise when stopped/at idle. It's not consistent and doesn't seem to affect drivability. I just hope it's not knock or slap, ie indicative of serious issues. Am I just being paranoid and overly sensitive, or has anyone experienced similar things?

My 2012 GX makes all kinds of noises when it starts up and shuts down unlike the LS 460 that I also have that is much more refined. Lexus says that the noises that the GX makes is normal for a truck.
