Thats the direct injection, sounds like a ticking time bomb

While we're talking about engine noises from these trucks... What's the "jingle" I hear at low-speed deceleration? Sounds like it might be more from under the truck as opposed to the engine. Sounds almost like it would be associated with an exhaust valve fluttering (which probably doesn't even exist, but is how/when I picture the noise occurring)...

There is an exhaust valve in front of the muffler that closes by spring and opens with exhaust pressure.
