Yes both of those bolts.
Ok great
Leak down is important as well and possibly more so than compression. Seen many times where a cylinder had good compression but bad leak down. Think of it as a more thorough compression test.
Hopefully I won't have to do that test but we will see.
I would check something first, the noise you hear does it go away when it warms up you said or when you get off idle?
I have an engine that does that I thought it was a flexplate or piston slap,turns out it was a thrust bearing.
The flexplate moves in and out 1/4" with the crank
When it's idling it's noticeable then you drive it and can't hear it. Been driving it for 8 years waiting for it to fall apart but I should have fixed it a long time ago.
Easy enough fix
To check put a pry bar on the flexplate and try to move it back and forth.
It will also tell you if it is the flexplate.
But after hearing the video it sounds like my engine
Engine makes that noise no matter the idle until the engine is fully warmed. Then it's barely audible. So I suppose it wouldn't be flexplate?
