⚠️ Common Signs of Failure

• Loss of compression and hard starting on one cylinder
• Rough idle with a puffing note back through the exhaust
• Valve seat face burnt, pitted or with a wedge missing
• Stem worn or scored where it runs in the guide
• Tulip cracked or the head distorted by overheating

🛠️ Service Notes

• Check the valve guide and seat for wear before fitting, as a new valve in a worn guide will burn again
• Renew the valve stem seal and re-cut or lap the seat so the new valve beds fully
• Reset valve clearances once the head is back on
