Ok, I moved around it as quick as I could listening and I have to say it doesn't appear to be coming from the cats.

Again, only code is bank 1 pre-cat is saying too rich. Otherwise nothing else is showing.

Here's a quick video as I was looking and listening. With all the stuff out of the way, I have to say it seems to be coming from the valve cover area around cyl 1 or 2. So I guess that cover is now coming off.

Again, it's not a deep motor sound like a rod. It's high pitched and inconsistent. I would say it's a bent pushrod if this was my LS car
