Cobalt 07 SS/SC Engine Knock

Hello,

Cobalt 07 ss/sc, 90k miles, had cat replaced by dealership at 79k. no other problems. 2 days ago, I hear this

Cobalt SS/SC Engine Knock

It comes from the passenger side of the engine or from the left when in front of the engine/car.

I have stage II. Never changed pulley, belt or injectors.

It seems to come from the engine on the far side of it.

Any comments, ideas, help welcomed!!!

Sincerely,

and sorry.. it takes a few seconds for the sound to come up
