## ⚠️ Common Signs of Failure

-   Excessive rocker-arm axial movement
-   Uneven wear on the sleeve or guide
-   Rocker misalignment
-   Incorrect valve or injector adjustment

## 🛠️ Service Notes

-   A spacer sleeve sets a fixed length in the joint — never leave one out, shorten one, or substitute a stack of washers, or the clamping load and alignment will both be wrong
-   Check that the sleeve is square and fully seated in its counterbore or recess before any fastener is tightened
-   Discard a sleeve that is crushed, bell-mouthed, scored or corroded; a shortened sleeve lets the joint be over-clamped and the component distorted
-   On sleeves in an oil circuit, make sure the bore is clear and that any seal running on the sleeve has a clean, unscored surface to work against
-   Tighten the joint to the figure in the workshop manual for your engine, with the sleeve taking the clamping load rather than the component it protects
