Just to clarify... I'm a gear head and have rebuilt a few engines in my day.(even an ol 1952 Dodge M-37 army truck straight 6)

Most definately valve train noise. And it's getting louder.
could be fuel injectors clicking as they use small solenoids that open and close the valves. sounds similar to valve train noise.

Which is why every single engine I've owned over the past 30 years, every single one of which had fine metal particles in the oil that made it past the oil filter (picked up by the magnetic oil plug on the cars I bothered installing those plugs on), disintegrated. Eventually. Like the Honda Civic that eventually disintegrated at 340,000 miles when it threw a piston rod thru the crankcase. Err, yeah .

Aluminum isn't going to score bearing surfaces or hydraulic cam positioners, and nothing that gets through the filter qualifies to be a "shard".

Well lets make this crystal clear YOUR theory is aluminum is harmless to a engine ? It won't clog a oil passage ? it will not get stuck in a oil filter check valve ? Well I could go on and on so to make this simple why not make a video of you pouring some aluminum directly into your engine ??? if as YOU say it is harmless then put your money where your mouth is ! I also if you bothered to read the whole thread said other dirt foreign to the engine can enter during the replace/rebuild process also the lifters are NOT made of aluminum steel and other metals which can be destroyed while the lifter is banging around the lifter bore If you are going to try to justify your point of view then get the video camera out and start pouring Oh and news flash your magnetic doodads you used on your engines do not pick up aluminum AND your engines that went 300,000 plus miles did NOT bang and rattle at 700 miles either !!!!! Geeeeez

That's just 100% false.

Not a dirty filter, but a plugged filter will open the bypass.

Plugged completely, yes. Dirty, no.

In retrospect it should have been obvious that Chyrsler would not be able to build a 280ish HP 3.6 liter V6.

Did anyone with this issue have a vibration of the engine while at idle? Mine started to vibrate. I can hear it inside the vehicle and when I put my hand on the engine cover it it is very noticable.

Capability wrapped in AWESOMENESS!!!

Question, if the tapping noise was serious would the noise get faster as you accelerate, or rev the engine in neutral?

Poll?

So...
Has anyone, by chance, initiated a poll to come up with some numbers/percentages on how many 2012 Pentastar's have this problem vs. the number of them that don't?

I tried a search, but no luck. Not that I'm a pro on that function...

If not, let's do it.
I'd like to see what my chances look like...
