The lifter in question is basically still intact, a little bloomed out, but not shaving off yet. Don't know if it could release enough metal to cause all that damage unless the cam lobe is near gone.
That is exactly my thought on the subject too. The lobes show some tracking marks, no pitting (although my close up photos may seem to suggest such) but the lobes are full height and full shape.
Now remember what you are looking at here....a cam lobe greatly
magnified. So the surface is better in real life view.
The first pic is the lobe for the bad tappet. The one with the Tig welding rod pointing to it.
The second pic is the backside of that same lobe.
The third pic is the #5 cam lobe that sits next to the bad tappet lobe.......pg
