Ishino JF-1640118-2 Valve Stem Seal

The Ishino JF-1640118-2 Valve Stem Seal is a precision-engineered replacement component designed to prevent oil from leaking into the combustion chamber through the valve guides. This seal creates a tight barrier between the valve stem and guide, ensuring proper lubrication control and preventing excessive oil consumption.

Key Features:

• High-temperature resistant materials withstand extreme engine conditions
• Precise fitment ensures proper sealing and valve operation
• Prevents oil seepage into combustion chamber
• Reduces blue smoke from exhaust caused by oil burning
• OEM-quality replacement component

Worn valve stem seals can lead to increased oil consumption, fouled spark plugs, and reduced engine performance. Replacing these seals during engine service or rebuild helps restore proper compression and oil control, extending engine life and maintaining efficient operation.
