## 🔌 Function

Returns the valve to its seat after the cam has opened it, and keeps the valve train loaded so it follows the cam profile.

## ⚠️ Common Signs of Failure

-   Noisy valve gear, particularly a tap that will not adjust out
-   Loss of power or a misfire at higher revs
-   Broken coil found on strip-down
-   Free length below specification when measured
-   Spring ends no longer square, or the coils rubbed bright

## 🛠️ Service Notes

-   Renew as a set rather than singly - mixed spring rates load the valve train unevenly
-   Four springs here run from 0.054 kg to 0.135 kg on different engines, so order by part number
-   Measure the free length of the removed springs before deciding what else to renew
