The Rocker Valve is a component of the engine's valve train system that is responsible for opening and closing the engine's valves. 

Here are some signs that the Rocker Valve may need to be replaced:

• Ticking or tapping noise: If the rocker valve becomes worn or damaged, it can cause a ticking or tapping noise to come from the engine. This noise may be more noticeable at idle or under light acceleration.
• Engine misfires: A worn or damaged rocker valve can cause the engine to misfire or run unevenly. This can result in a loss of power or reduced fuel efficiency.
• Oil leaks: If the rocker valve becomes damaged, it can cause oil to leak out of the engine. This can result in low oil levels and potentially cause engine damage if left unchecked.
• Visible damage: If the rocker valve appears visibly worn, cracked or broken, it may need to be replaced.

In general, Rocker Valves do not need to be replaced unless they become worn, damaged or broken.
