Possible Rod knock?

Hey guys and gals,

I'm having a hell of a time trying to diagnose my 99 Legacy B4 twin turbo motor.

 

I'm hearing a knock, it isn't load and you can barely hear it.

 

The spark plugs were changed about 2/3 months ago, I was told to check the gaps but I'm sure sold that, that is what it could be.

 

I changed the oil to 10w-40 and I put awhole bottle of Lucus Oil treatment.

 

Still knocks, I used the famous screw driver to block trick and I hear the knock in the back 2 cylinders.

 

I attached a video. It sounds loud in video but it isn't that loud.

 

Can anyone help?

 

Thanks! http://cloud.tapatalk.com/s/5ee6e9094166c/VID-20200614-WA0000.mp4
