20864662 — 12 Pcs Valve Steam Seal Kit 20864662 20802229 For Volvo Engine D11 D12 D13 Truck Fh Fm Prevh Prevx

This valve stem seal kit is designed to prevent engine oil from entering the combustion chamber through the valve guides, ensuring proper sealing and combustion efficiency. Manufactured to strict Volvo standards, these seals offer superior durability and resistance to heat and oil compared to worn or brittle seals that allow oil to leak past. Operators may notice blue smoke from the exhaust, particularly on startup or deceleration, and an increase in oil consumption.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Worn valve stem seals will initially cause intermittent blue smoke from the exhaust, especially noticeable after the engine has been running for a while or when decelerating. If left unaddressed, this oil consumption will increase, leading to fouled spark plugs, catalytic converter damage, and potential engine performance issues. Excessive oil burning can also lead to carbon buildup on pistons and valves.

Installation Tip

When installing new seals, ensure the valve stems are clean and free of burrs. Use a proper seal driver to avoid damaging the seal or the valve stem.

Service Note

It is recommended to inspect valve guides for wear and replace valve springs if they show signs of fatigue when installing new valve stem seals.
