## 🔌 Function

Follows the camshaft profile and transfers that motion to the pushrod, converting cam lift into valve gear movement.

## ⚠️ Common Signs of Failure

-   Ticking or tapping from the valve gear that does not clear when warm
-   Valve clearances drifting out between checks
-   Rough running on one cylinder as lift is lost
-   Tappet face found pitted, cupped or with the hardening broken through
-   Tappet body worn in its bore, giving side play, with matching wear on the cam lobe

## 🛠️ Service Notes

-   If a tappet face has broken up, inspect the matching cam lobe and change the oil and filter, since the debris will have circulated
-   Renew tappets as a set where several are marked and reset the valve clearances after fitting
