2014 Gen 1 (Rod Knock) Sound. Need help.

Does the sound go away when transmission is put into D or R or just when fans kick on an place load on the engine etc.
Since the fans are electric and and the sound goes away when they kick on, I would be looking at the front accessory drive as well. Weird that the noise is coming from the back of the engine.

I’d suspect a cracked flex plate. It sounds just like a rod knock.

Any update on this? I just bought a 2014 with 170k miles and 1 week ago my truck has developed this same exact tapping noise on the top of the engine, driver's side, by the firewall. My engine also runs like a champ, and throws no codes.

What is the chance this is the same truck? OP was from Kingsport TN. and you are from Chattanooga TN.
Lets get a pic of this truck. The OP never posted one. He was a one post wonder.

The flex plate was cracked around the bolt holes.

Yea, that's what it ended up being. Each bolt hole was developing minor cracks.

Good news? They're cheap. Bad news? It's not fun replacing.

I appreciate that info. Looks like I'll be researching a write up or video for that repair.
This truck last came from Alabama. I'll keep you all posted on the outcome.
