I'll look for it.
I understand your comment now. Yes, if the damage was severe enough to actually break the cap, I'd go along with you that it reflects poorly on the tech, depending on severity and location of the damage.
The usual problem is called the rotor bracket, which is a metal piece that attaches to the front of the camshaft, but on the front of the front cylinder head cover. The rotor attaches to this bracket with 3 small machine screws. The bracket can crack radially, which means that the rotor tip won't neccesarily be pointing at the correct cylinder anymore inside the cap.
