Excellently maintained. 195 k miles. Not the ticking noise. Pretty sure that's a lifter. The knocking noise has been there for a very long time. It's worse when it's cold. But this is after being thoroughly warmed up.

Tried to post a video from my Pixel phone and it said something like the wrong format. Needs to be JPEG or another acceptable format.

How can I do that? Sorry....I'm not good with this tech stuff.

You have to upload it to a hosting site like YouTube. The site locally only does pictures, and not clips/movies.

Usually knocks (especially rod knocks) get worse with heat not better... I'd lean toward piston slap without even hearing it...
