## ⚙️ Key Features

-   Engine group valve spring
-   0.026 kg
-   Supersedes part number 3581889
-   Covers 124 D series engine applications

## 🔌 Function

Closes the valve and holds it hard against its seat, keeping the follower in contact with the cam through the whole of the lift.

## ⚠️ Common Signs of Failure

-   Ticking or clatter from the valve gear
-   Misfire or loss of power at higher revs as a valve floats
-   Spring found broken, usually close to a coil end
-   Coils rusted, or fretting where they touch, on strip-down
-   Free length measuring short against a new spring

-   Springs are matched to the valve gear - fit a full set rather than a single spring where one has broken
-   Check the valve, guide and seat for damage before reassembly, as a broken spring often takes the valve with it
