Weird hissing sound, sounds like escaping air while running
Engine idles fantastic, no loss of power.
With the hood open it's quiet up top. The sound is definitely coming from below. When I shut the truck off the hissing continues for a couple seconds, suggesting it's not a pully (second suggestion is the sound is below all the pullies. It's not coming from the front of the engine)
Ideas?
Ignore that knocking sound you hear, the truck has always done that.

Thats not an exhaust leak, and I wouldnt suggest plugging your exhaust with a towel. My 02 4.7 makes a similar sound, not quite as loud though, and it does continue for a second or so after I shut the truck off. I've never worried about it but now that you bring this up I am a little curious, Ill look into it and let you know what I find out.
