## 🔌 Function

Controls valve timing through its machined lobes.

## ⚠️ Common Signs of Failure

-   Abnormal valve-train noise develops
-   Engine power falls or the engine runs unevenly
-   Cam lobes or journals are scored, pitted or worn
-   Metal debris appears in the engine oil
-   Valve timing or engine-braking performance becomes incorrect

## 🛠️ Service Notes

-   Oil the journals and lobes before fitting and lower the shaft in squarely, without dragging it across the bearings or bearing bores
-   Inspect the parts that run with it as a set — followers or rockers, bearings and the drive gear — and renew anything worn; a new camshaft on worn followers will not last
-   Line up the gear timing marks and check valve timing before turning the engine over, and never force it against resistance
-   Tighten bearing caps and drive gear fixings in the sequence and to the figures in the workshop manual for your engine
-   Prime the oil system and turn the engine through by hand for a full cycle before starting, then keep the first period of running gentle
