Yea, Chuck sent me that rocker arm and I keep it on my desk for grins. It is a magnitude ten worse than anything I have ever seen before.
The first picture that clearly shows a line across the face of the rocker pad is just getting to the point where it will take out the cam lobe. As soon as the line gets deep enough to go through the hardening both it and the cam will be history. It will have been noisy for some time.
