Cam Lobe Pictures, Need Analysis Help

[Gaz64]

Wayne,

Have you inspected the roller?

Can you post pics of the lifter roller?

We can see the overheated blueing on the shaft which extends further away from the lobe on the base circle compared to the nose.

It shows the amount of friction the failed roller has caused.

You may not be able to feel it with your fingernail, but it is there, it is an abnormal wear pattern, and it would have become a catastrophic failure.

The ground up metal, as small as it is, would have passed through the oil pump first before the oil filter traps it.

Inspect your oil pump as well.
