What happens is when the connector ends break, the oiler tube has no oil pressure because the oil leaks out at the broken connector. No pressure means no oil coming out of the little holes and dribbling on the cam. After about an hour of running the cam dry, the lobes are toast.

And yes, Peter means that they try to reuse the tube and broken plastic bits.
