Knock knock who's there?

I ran my 861 for about hours today mowing. The stumbling downhill seems better. Still blowing a fair amount of blue smoke out the tailpipe.

The engine noises seem loud. I've never heard a knocking engine so I don't know if that's what I am hearing. I took a quick video. Maybe someone here can tell me what I am hearing.

Video doesn't upload as it is too big. Let me try to work around it

Worn crank and cam gears will rattle a lot when not using the lift. they will quiten when you lift something. Also the hydraulic pump gears will rattle if worn too much. I have one engine that i thought had a loose rear cam gear and I was trying to tighten the bolts and discovered that the gear was tight but lifted when pryed a little. Its either a worn block or cam.
