Got CEL (check engine light)

Check the knock sensor might not be retarding the ignition timing when it starts to detonate/ping-also the EGR valve -

the CEL is not on and all the sencers are good. I did take the vavle covers off and found several of the racker arms were loss ( as in the top of the arm itself moves freely) as if the lifters might be durty. Im goin to try that to see if it goes away.
