Comp Cams called this morning and said they'd never seen that kind of failure and would like to get the timing gear back for inspection. That's not the kind of failure they need to see with their parts.

That being said, Comp has offered to send me a replacement cam, lifter, and gear set.
This cam was a custom grind due to the possible installation of turbos. When I box it all up for return I'll have to see if they can add a bit more lift and fatter lobes. Maybe it'll help make a bit more power.
