I pushed the corresponding follower out through the bottom and what should have been a very slight convex face was a very defined concave to match the nicely rounded cam.
On the plus side, everything else looks to be in really nice condition and having check a couple of big-ends, they look perfect with absolutely no signs of marking, let alone scoring.
I think I may have dodged a bullet.

The lifter and the lobe disappear like this from lack of rotation.

Can happen suddenly and failure occurs in a short period.
