Description

Victor Reinz 12-41303-01 is an OE-quality valve stem seal set for BMW N57 and B57 3.0 diesel engines.

Designed to prevent engine oil from entering the combustion chamber through the valve guides, these seals help reduce oil consumption, minimise exhaust smoke and maintain optimum engine performance.

Worn valve stem seals can cause:
✔️ Blue smoke from exhaust
✔️ Increased oil consumption
✔️ Fouled glow plugs
✔️ Carbon build-up
✔️ Reduced engine performance

Recommended during:
✔️ Cylinder head overhaul
✔️ Valve replacement
✔️ Engine rebuilds
✔️ High-kilometre maintenance
