Hengst 958-101-247-04 Engine Crankcase Vent Valve Oil Separator Assembly

The Hengst 958-101-247-04 is a direct-fit replacement crankcase vent valve and oil separator assembly engineered to restore proper crankcase ventilation system function. This component — also referred to as a PCV valve assembly or crankcase breather — regulates internal crankcase pressure by providing a controlled, one-way exit for blow-by gases generated during normal engine operation.

The integrated oil separator works in conjunction with the vent valve to safely route blow-by gases back into the intake system while preventing oil mist from escaping into the engine's air intake. Hengst is a globally recognized OE-level filtration and fluid management supplier, manufacturing crankcase ventilation components to strict OEM specifications.

Key Features:

• Replaces OEM crankcase vent valve and oil separator assembly
• Restores proper crankcase pressure regulation to prevent seal failure and oil leaks
• Integrated oil mist separation helps protect the intake system from oil contamination
• Manufactured by Hengst to OE-equivalent specifications for fit, form, and function
• Helps reduce rough idle, pressure loss, and performance issues caused by a failed PCV system
• Direct replacement — no modification required

A faulty crankcase vent valve can allow excessive pressure to build inside the engine, leading to oil leaks, rough idle, and reduced performance. Replacing this assembly with the Hengst 958-101-247-04 ensures the crankcase ventilation system operates as designed, protecting engine seals and maintaining optimal engine efficiency.
