🔌 Function

Follows the camshaft lobe and passes that lift on to the pushrod, converting the cam profile into valve movement.

⚠️ Common Signs of Failure

• Ticking or tapping from the valve gear, worst when cold
• Valve clearances drifting out of specification between services
• Cam-follower face pitted, scuffed or dished on strip-down
• Tappet worn in its bore, giving side play or a rattle
• Metal glitter in the oil or on the filter

🛠️ Service Notes

• Inspect the matching cam lobe and pushrod end whenever a tappet is worn — they wear as a pair and fitting one new part against a worn mate does not last
• Renew the full set if several are worn, and reset the clearances after fitting
