Hydraulic Lifters

Wow, these are some pretty sad looking lifters:

Lifters 2 and 4


Funny thing is, these were included in an engine that was just fully disassembled, cleaned, inspected, and signed out from an Engine Overhaul Facility. We found metal in the filter and went looking for answers…I have never seen such an obvious problem after only about 10 hours of run time. Shame on the person who signed these off as serviceable.
