## ⚙️ Key Features

-   0.095 kg
-   63 applications across six engine series
-   Inlet valve, paired with exhaust valve 838638
-   Quantity varies by assembly, most commonly four

## 🔌 Function

Opens to let the air charge into the cylinder and seals the combustion chamber against compression and firing pressure when closed.

## ⚠️ Common Signs of Failure

-   Compression loss and hard starting
-   Uneven idle with an irregular exhaust note
-   Valve face or seat pitted, carboned or burnt
-   Stem worn or bent so the valve does not seat squarely
-   Valve clearance drifting out of specification

## 🛠️ Service Notes

-   Exhaust valve 838638 is the matching exhaust valve at 0.138 kg, a clear 43 grams heavier, so the inlet and exhaust are distinguishable here but should still be ordered by part number
-   Inlet valve 838125 is a separate 0.095 kg inlet valve covering only 2 MD applications, so identical weight does not mean identical fitment and the application list must be checked
-   Renew guides and stem seals as required and lap each valve to its own seat

## 📦 Condition

-   Genuine Volvo Penta part
-   Brand new
