Damn man! Never a dull moment. How are your oil levels? Have you been driving it, and if so, how much had you before it started knocking?

It does sound a little loud..Pop your hood and take another video from the top of the engine bay.

I am fairly positive that is not knocking. Sounds like valve train noise. Knocking typically happens under load and is less of a tick-tick-tick sort of noise. That sounds too rhythmic to be knocking.
Legz and Staples like this.

Sorry to hear that, whatever it may be, doesn't sound good at all.

Just so I am on the same page as everyone. Knocking on these engines typically means a bent rod right?

O first to answer everyone at once. Oil level is full, had it changed last week . I can not hear it from the top of the motor only down behind the passenger tire. i like some off the replies its not knock. But if it was the timing chain should I hear it up top also?. And yes the noise is there at idle but will get louder driving.

Maybe an exhaust leak. Have you removed the O2 sensors? Or have you had the headers out? It doesn't sound like a knock to me either but it's tough to tell on video.
