🔌 Function

Packs a running clearance by a fixed amount, so it is ordered against the measured clearance rather than the engine.

⚠️ Common Signs of Failure

• Valve gear noisy, with a tap that does not clear as the engine warms
• Measured clearance outside specification
• Contact face worn bright, pitted or stepped
• Washer showing uneven or one-sided wear

🛠️ Service Notes

• Measure and calculate the size needed, then order by thickness, since the published weights across this series are inconsistent
• Inspect the follower and cam lobe before assuming the washer alone is at fault
