Lifters....valve clatter on M30 motors?

Is the M30 known for this? It's not excessive but I think there is one particular valve that might have an issue. I tried listening with a stethoscope but could not pin point which one it is? Any thoughts?

Sure, just adjust the valves.
And there are no lifters, just rockers.

I already adjusted the rockers. Didn't seem to help much.

They're not silent engines, but you've been around them for a while now and know what they sound like. Try readjusting them, I know one time I did valves and got one just on the start of the ramp when I adjusted it. Was .016 or something but made way too much noise.
