The side to side play is not your main concern. You want to check the up/down play. I don't know what the acceptable up/down tolerance is though.

Any noticeable radial play isn't good
Side play is ok at 1 or 2mm range

If you can feel up and down play I'd say its too much.

Up and down is non existent. Side to side is what i was worrying about, but if you guys say up to 2mm is fine, then i'll just leave it as is.

side to side per service manual, with a feeler gauge in the connecting rod standard 0.8mm, limit 1mm

Up/down, doubt you can feel it installed...

Judging by the video it is ok....
