It’s hard to isolate the noise you’re hearing in a video sometimes. What type of noise are we listening for? I didn’t hear any knocking.

 

it’s not knocking that I’m hearing just sounds like a hissing. I could be going crazy lol

 

I hear what you’re talking about. It could be the sound of the intake sucking, but it’s hard to gauge how loud it is in person from the video to be honest. Mine sounds similar.

 

Sounds like a bearing on whatever is on the passenger side of the engine. I mean something belt-driven, not the actual engine itself. I got an alternator wet and it made a similar sound.

 

Bad bearing on something. Get mechanics stethoscope and check alternator first. That would be my bet.
