This breather valve is engineered to fit the cylinder head, providing reliable emission control for models such as the Volkswagen Beetle, Golf, and Jetta.

  • Pressure controlled breather valve for effective crankcase ventilation
  • Durable polyamid 6.6 housing material
  • Compact dimensions: 112 mm length, 86 mm width, 52 mm height
  • Lightweight design at 0.072 kg
  • Recommended replacement interval of 60,000 km or 3 years

Detailed Product Description

The VAICO V10-2591 Engine Crankcase Vent Valve is a critical component within the emission control system, specifically designed to regulate crankcase pressure by allowing gases to escape from the cylinder head. Constructed from polyamid 6.6, the valve housing offers resistance to heat and chemical exposure commonly found in engine environments. Its pressure-controlled operating mode ensures that the valve opens and closes in response to engine pressure changes, maintaining proper ventilation and preventing oil leaks or pressure buildup.

With precise dimensions of 112 mm in length, 86 mm in width, and 52 mm in height, this valve fits securely in the designated cylinder head position. The lightweight design at just 0.072 kg contributes to efficient engine performance without adding unnecessary mass.
