⚙️ Key Features

• 0.015 inch oversize
• 0.175 kg
• 96 applications across the DPX series
• Middle of three sizes with 3861336 and 3861338

🔌 Function

Seals the combustion chamber during compression and firing, then opens to release burnt gas into the exhaust port.

⚠️ Common Signs of Failure

• Loss of compression on one cylinder, with rough idle
• Burnt or blowing note through the exhaust
• Head face burnt, pitted or notched on strip-down
• Stem worn or bent, giving excess guide clearance
• Valve clearances closing up as the seat recedes

🛠️ Service Notes

• Measure the guide before ordering, as the oversize step must match the reamed size and not the wear found
• Only 14 grams separate this from the standard valve 3861336, so the size marking rather than the weight is the guide
• Renew the valve spring 3861335 at the same time

📦 Condition

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