Diesel Sound Coming from Engine or Elsewhere?

Does anyone else notice what sounds like a diesel engine? I hear a constant ticking or what I would best describe as a diesel engine sound. I notice it most with windows rolled up. I don't hear it from outside the truck. I have a V6.

 

My other truck is a 2012 Ram 3500... this sounds nothing like a diesel.

 

completely normal... its your self cleaning injectors self cleaning themselves... usually at idle I hear it.

 

Atkinson cleaning cycle. Completely normal

 

High quality 3.5 construction. It's the self destruct cycle, wait to see how it sounds at 100k lol

 

Those are the direct injectors.

 

Third gen still ticks like a sewing machine? I thought that was just a second gen deal. At any rate Op, My 4.0 has been doing that randomly for years. I quit worrying about it.

 

The turd gen makes the second gen ticks sound silent. Sounds more like a vw tdi idling in my garage.

 

This, direct injection is loud. Which is what a diesel uses also.

 

Yeah mine does that too, .... I can honestly say the sounds from this engine are not high tech... but I know that this motor does have a few tech features that help its durability.
