Have I missed something? I've heard about "roller needles" and I've seen a pic of a fragment that isn't a roller needle. And I've heard about a prior rocker failure which MIGHT be the source of the debris. But I didn't hear any plan to check all existing sources of the roller needles. The magnets and screens may stop metallic fragments from getting in the pump but if the failure is a CURRENT component (rocker, lifter, cam bearing) then firing up and running will result in another damage event. And the fact that it ran for a while doesn't preclude an existing damaged component. You don't have to pull the engine to check other sources of debris. Good insurance policy.
