⚙️ Key Features

• 0.030 inch oversize
• 0.104 kg
• 53 applications
• Oversize partner to standard valve 3855808
• Quantity varies by assembly, most commonly one

🔌 Function

Opens and closes a cylinder head port in time with the camshaft, with an oversize stem to suit a guide that has been reamed out.

⚠️ Common Signs of Failure

• Valve sticking or slow to close in a guide that is not correctly sized
• Ticking or tapping from the valve gear
• Misfire or lost compression on the affected cylinder
• Stem found scored or picked up in the guide
• Oil drawn down a worn guide, showing as smoke on start-up

🛠️ Service Notes

• Only order this version once the guide has been machined to accept a 0.030 inch oversize stem
• Standard valve 3855808 has exactly the same published weight, so weight cannot separate the two and the order must be placed by number
• Check stem-to-guide clearance after fitting rather than assuming the machining is correct

📦 Condition

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