Key Takeaways:

Pushrods and rocker arms frequently experience abnormal wear or breakage across various aircraft types, sometimes occurring shortly after replacement.
Common causes for these failures include insufficient oil lubrication (oil starvation), a valve stuck in the closed position, or suspected design flaws in newer engine models.
Such component failures can lead to significant engine problems like rough running, zero oil pressure, metal contamination, failed compression checks, and extensive internal engine damage.
