Hello please help. I have a ZZ4 crate motor in my car. Recently a funny clanging noise starting coming from the driver's side value cover. I tightened the rockers but the noise did not stop. Any idea what the the problem could be?

Do the valve covers have a tin baffle under the PCV/vent hole? If so, it might have gotten loose or c0ckeyed and started hitting a rocker arm.

What did you mean by tightening the rockers?
