## ⚠️ Common Signs of Failure

-   Loss of compression with a puffing sound at the exhaust
-   Burnt or pocketed valve face, sometimes with a notch in the edge
-   Stem worn or the head necking down near the fillet
-   Guide clearance excessive, with oil drawn down the stem
-   Clearances closing up between services as the seat recedes

## 🛠️ Service Notes

-   Renew the valve guide and recut the seat when fitting a new exhaust valve, as guide wear is what burnt the old one
-   Valve guides 422320 and 422762 cover other engines in this range, so match the guide to your engine before ordering
-   Never refit an exhaust valve with a necked stem, as failure drops the head into the cylinder
