⚠️ Common Signs of Failure

• Ticking or tapping from the valve gear that rises with engine speed
• Valve clearances drifting out of specification between services
• Pad or tip worn hollow, pitted or scuffed
• Bore or bush worn, giving side play on the shaft
• Adjuster thread damaged, seized or the locknut no longer holding
