## 🔌 Function

A formed upper-engine cover that encloses the rocker gear and contains lubricating oil while supporting the specified ventilation and sealing arrangement.

## ⚠️ Common Signs of Failure

-   Oil leakage around the cover perimeter
-   Cracks or distortion around fasteners
-   Crankcase-vapour leakage
-   Contact with rocker components
-   Repeated gasket failure from a warped sealing face

## 🛠️ Service Notes

-   Fit a new gasket or seal whenever the cover comes off, and clean both faces down to clean, dry material without scoring them — use a plastic scraper on aluminium and on moulded covers, never an abrasive disc
-   Check the cover itself for distortion and for cracks around the bolt holes, and renew the sealing rings, grommets or spacers that sit under the bolts along with it
-   Draw the bolts down evenly from the centre outwards to the figure in the workshop manual for your engine; over-tightening distorts the cover and crushes the gasket, which is the usual reason a freshly gasketed cover still leaks
-   Make sure the breather, oil filler and any sensor or fitting carried in the cover are clear and correctly sealed before it goes back on
-   Degrease the area after fitting so that at the next check a genuine leak can be told from residual oil
