Aftermarket 11617531423 Engine Oil Separator PCV Valve

The Aftermarket 11617531423 Engine Oil Separator is a direct replacement for the BMW OEM crankcase ventilation valve. This essential emissions component separates oil vapor from crankcase gases before they are routed back into the intake system, preventing oil contamination and maintaining proper engine performance.

Key Features:

• Direct fit replacement for BMW OEM part number 11617531423
• Integrates oil separator and PCV (positive crankcase ventilation) valve functionality
• Prevents oil vapor from entering the intake manifold
• Helps maintain proper crankcase pressure and ventilation
• Constructed with durable materials to withstand engine heat and pressure
• Includes integrated heating element to prevent freezing in cold conditions

A failing oil separator can cause rough idle, increased oil consumption, intake system contamination, and check engine lights. This aftermarket replacement restores proper crankcase ventilation system operation at a cost-effective price point compared to OEM parts.
