⚙️ 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

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
