Key Takeaways:

Multiple reports detail failures and excessive wear of pushrods and rocker arms across various Cessna and Piper aircraft models.
Common causes include oil starvation, valves stuck in the closed position, and suspected design flaws leading to insufficient lubrication.
These issues manifest as abnormal wear, breakage, or bending, often resulting in symptoms like rough engine operation, metal contamination, and internal engine damage.
