⚙️ 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
• Supplied in original or equivalent packaging
