Ticking noise, 383, can't locate the source

Family stuff today, but I had a few minutes, pulled it out on the yard.

Tried the thumb trick and was unable to locate or make it stop.

My neighbor will probably call the epa on me though for the oil spill.

Took a few quick videos. It's definitely louder in person.

I will pull the rocker shaft asap and see what I can see.
