Chain noise?

My car has 85K miles and it runs like a champ and revs smooth beside this strange, very isolated noise.

I never checked cam deviation, I’ll look into it. Anybody here around Detroit with the proper scanner? I got Autel with no such ability...

My filter was clean in my first ever oil change. I then dropped the sump to install a guardian. There was little bit of those chain ramp plastic in the sump. I was always thinking they might never reach the oil filter because they are to heavy to suspend in the oil and reach the filter.
