High compression timing issue.

This rocker arm is very loose. Is this normal? Appears to be exactly where I was hearing the noise from. I haven't rotated engine yet to see if the 'slop' may be due to the position of the cam, or loose lifters, etc...

I still have some research to do about what else may be wrong. I will have a couple hours to work on it again tomorrow and ill be double checking the valve spring on that last cylinder.

Any thoughts based on my latest video?
