-   Supersedes 21306203 and 21186009

## 🔌 Function

Provides the hard machined ring the valve closes against, sealing the combustion chamber and carrying heat away from the valve face.

## ⚠️ Common Signs of Failure

-   Compression down on one cylinder with hard starting
-   Misfire or uneven running, worst when cold
-   Valve clearances closing up between checks
-   Seat found pitted, recessed or cracked on strip-down
-   Burnt valve face against a sunken seat

## 🛠️ Service Notes

-   Seats are an interference fit and need cutting and lapping to the valve after fitting — this is machine shop work, not a bench job
-   Renew the valve and its guide at the same time if either shows wear, or the new seat will not seal for long
