8631652 Valve Stem Seal | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta valve stem seal from the Engine group, listed for 70 applications on D series engines — the same broad D series coverage as the inlet and exhaust valves 8631650 and 8631651 listed here, so it is the seal that goes with that valve gear work.

🚤 Compatibility

• Engine Family: D
• HP Range: 110-220 HP

⚙️ Key Features

• Engine group
• 70 applications on the D series
• Matches the D series coverage of valves 8631650 and 8631651

🔌 Function

Wipes oil from the valve stem as it moves, letting just enough through to lubricate the guide while keeping the rest out of the port.

⚠️ Common Signs of Failure

• Puff of blue smoke on start up or after the engine has idled for a while
• Blue smoke on the overrun when coming off the throttle
• Oil consumption with no external leak to account for it
• Oily deposits found on the valve stems and in the ports on strip down
• Seals found hardened, cracked or with the lip worn away

🛠️ Service Notes

• Renew all the stem seals as a set rather than one at a time, as they age together
• Check the valve guides for wear before fitting new seals, since a worn guide will destroy a new seal quickly

📦 Condition

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