861700 Valve Seal | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta valve seal from the Engine group, weighing 0.002 kg and listed for 18 applications across the D series. It supersedes 877072 and 877073, both of which were catalogued earlier simply as valves, so an old parts list may point you at a valve when the seal is what is now supplied.

🔌 Function

Wipes the oil from the valve stem as it moves, letting just enough through to lubricate the guide.

⚠️ Common Signs of Failure

• Puff of blue smoke on start-up or after a spell at idle
• Oil consumption rising with no external leak to account for it
• Seals hard, cracked or perished when the head comes apart
• Oily deposits on the valve stems and in the ports

🛠️ Service Notes

• Renew all the seals in the head as a set rather than one at a time
• Check stem-to-guide clearance before condemning the seals, as a worn guide will kill new ones quickly
• Valve stem seal 861860 is the other seal listed here and shares the same 0.002 kg figure, so order by number
