Default Air hissing noise under engine/transmission!

Hi all,

I just bought my '02 Quad Cab 4x4 with the 4.7 V8 and 5-speed less than a week ago! I love this truck!!! Great forum too! I was curious about something though. Whenever the engine is running, there is a very loud hissing, or whooshing, noise coming from under the truck around the middle of the engine/transmission area. When I turn off the engine, the noise does not just stop, it continues to sound like it is leaking for a couple of seconds.

Is this possibly something to do with engine vacuum? Is there something under there that would cause this? The truck runs great, and I have had other cars with vacuum leaks and usually they do not run that well!

Thanks in advance,
Daniel
