Genuine Mercedes-Benz Crankcase Vent Hose with PCV Valve

Restore your vehicle’s engine ventilation system and maintain optimal crankcase pressure with this genuine Mercedes-Benz Crankcase Vent Hose with an integrated PCV / breather valve. Engineered to factory specifications, this critical line safely recirculates blow-by gases from the crankcase back into the combustion system, keeping your engine running clean and efficient.

Over time, plastic and rubber PCV hoses become brittle due to intense engine heat cycles, leading to cracks, vacuum leaks, oil seepage, or a stuck valve. Common symptoms of a failing vent hose include a rough idle, unexpected oil consumption, a whistling noise from the engine bay, or a triggered Check Engine Light (CEL). Replacing your worn line with this brand-new, genuine component seals the system perfectly, protects internal engine components, and eliminates unmetered air leaks.

Key Highlights:
• Genuine Mercedes-Benz OEM Component: Provides flawless fitment, high-grade heat resistance, and long-lasting durability.
• Integrated Valve Design: Restores correct vacuum regulation and airflow dynamics within the emissions loop.
• Direct Replacement: Built to match your original factory line layout for a straightforward, reliable installation.
