That was my conclusion too Tim.

Now with that said, and I'm going to put it out there for anyone else that ever has to pull cams from the M276/278, go ahead and replace all of the cam roller/followers while it is opened up. Easy to do with the cams out.

The cam was not damaged at the bearing surfaces (indicating no loss of oil) it was damaged on the lobes. That was either caused by the timing adjuster being worn out jacking the cam around or the roller/follower going bad. I did find indications on a couple of the roller/followers where there was no cam lobe damage.
