• Oil consumption rising with the exhaust wet or sooty
• Valve gear ticking that returns soon after adjustment
• Valve stem rocking noticeably in the guide when checked by hand
• Seat face worn unevenly because the valve is no longer landing square

🛠️ Service Notes

• Renew the stem sealing rings 859659 and 859660 with any guide work, and recut or lap the seat afterwards so the valve lands square
