How to physically see and feel a bad roller lifter

Thanks for the response! Kim I did the garden hose tech and it sounds like it’s coming from both sides.

I removed the valve cover, there’s no slop pressing the rocker tip down, although I feel some side to side on 2 rockers.

I’m thinking I might of added too much preload, not allowing the lifter to compress causing a tick? Car runs great idles well also
