If the push rods are found to be bent, what is the recommended action?

In the context of small engines, if bent push rods are discovered during inspection or maintenance, the recommended action is to replace them. This is because bent push rods can indicate that the engine has experienced excessive stress or damage, potentially impacting the engine's performance.

Replacement is necessary to ensure that the engine operates efficiently and avoids further issues. Bent push rods may not function properly even if straightened, as they can maintain internal stresses and might not achieve the correct alignment needed for proper valve operation.

Moreover, adjusting or cleaning the push rods would not address the underlying structural integrity issues caused by bending. Ensuring that all components are in optimal condition is crucial for maintaining engine performance and reliability, making replacement the most effective and sensible choice.
