## ⚙️ Key Features

-   Standard size
-   0.129 kg
-   79 applications across the V family
-   Engine group
-   8 used per assembly

## 🔌 Function

Opens and closes the port against its spring, sealing the combustion chamber on the closing stroke and passing heat out through its seat and guide.

## ⚠️ Common Signs of Failure

-   Loss of compression and a misfire on one cylinder
-   Puffing back through the inlet or exhaust as the engine turns
-   Hard starting with a rough idle that improves as revs rise
-   Head or seat face pitted, burnt or receded
-   Stem worn or bent, or the tip hammered

## 🛠️ Service Notes

-   The Inlet and Exhaust group also lists a late-specification valve as 3857761 at 0.100 kg, so the group and the standard or late marking decide the order
-   Check the guide and seat with the valve out — a new valve in a worn guide will burn again quickly
-   Lap or recut the seat as the manual requires and reset the clearance after fitting
