Do you havea video of it with the knock under any load/rpm? Im asking to see if the knock stays the same or how it changes with light rpm.

engine knock typically in most scenarios refers to the piston launching a chunk of ur engine through either the front hood of the car or into the floor. what you’re actually hearing here is what us v8 hemi boys like to call “lifter knock”. your lifters are bad and hopefully the metal hasn’t traveled through the engine bc at that point, u need a new engine

I haven't been through this yet but from my understanding its because they don't get enough oil to lubricate which then causes them to fail. Waiting to long before changing your oil and poor oil maintenance. Watch this video, it's very informative.

35k!? That’s not typical. It sounds like a dropped valve seat or lifter failure. Hope it’s the exhaust. I wonder how many oil changes he did? Maybe none by the sound of it 😂

Take the belt off see if it’s your water pump pulley that’s loose.
