## ⚠️ Common Signs of Failure

-   Blue exhaust smoke appears after idling or start-up
-   Engine oil consumption increases
-   Oil deposits form around the valve stem or combustion chamber
-   The seal is hardened, split, loose or damaged during cylinder-head service
-   Excessive oil enters the inlet or exhaust port through the valve guide

## 🛠️ Service Notes

-   Renew all the stem seals while the head is off rather than one at a time
-   Check the valve guides for wear first, because new seals will not cure oil consumption through a worn guide
