⚠️ Common Signs of Failure

• Blue smoke on start-up or after idling for a while
• Oil use climbing with no external leak
• Seals hard, cracked or perished when the head is stripped
• Oily deposits down the valve stems and in the ports

• Renew all the seals in the head together rather than singly
• Check stem-to-guide clearance first, as a worn guide will destroy new seals
