## ⚙️ Key Features

-   From the Engine group
-   0.005 kg
-   8 applications across MD engines

## 🔌 Function

Gives the valve a hard, replaceable face to close against, sealing the combustion chamber and carrying heat out of the valve head.

## ⚠️ Common Signs of Failure

-   Compression lost on one cylinder with a hard start when cold
-   Seat pitted, burnt or recessed into the head
-   Valve sinking, so the clearances keep closing up
-   Seat found loose or moved in its recess

## 🛠️ Service Notes

-   Fitting a seat insert is machine-shop work: the recess has to be cut true and the seat cut to the correct angle and width afterwards
-   Renew the valve at the same time, as an old valve will not bed properly on a freshly cut seat
