Womala Engine Crankcase Breather Hose OE 1020944387 for Benz 190 W201
The Engine Crankcase Breather Hose (OE: 1020944387) is a critical component of the ventilation system for specific Benz 190 W201 models equipped with the 102962 M 102 engine. Installed in the engine crankcase ventilation circuit, it guides blow-by gas (a mixture of unburned fuel, oil vapor, and air) from the crankcase to the intake system for re-combustion. As an OE-grade part, it meets Benz’s strict standards for high-temperature resistance, oil resistance, and structural durability, ensuring seamless integration with the engine ventilation system and reliable operation across diverse conditions (e.g., long-term engine operation, high under-hood temperatures).
Constructed from high-performance materials: the hose body uses heat-resistant and oil-resistant rubber (to withstand engine oil vapor and high temperatures), while the connection ends feature reinforced structures to prevent loosening or cracking, ensuring airtightness and long service life.
Core Functions
Crankcase Ventilation: The primary function is to discharge blow-by gas from the crankcase, reducing internal pressure and preventing oil leakage from seals or gaskets.
Emission Control: Guides blow-by gas back to the intake system for re-combustion, reducing harmful hydrocarbon emissions and complying with environmental regulations.
Oil Quality Protection: Prevents excessive pressure buildup in the crankcase from diluting engine oil or degrading its lubricating performance, extending oil service life.

This Engine Crankcase Breather Hose is tailored for the following Benz models and their respective OE number:

Notes:This Engine Crankcase Breather Hose is model- and engine-specific—it is tailored for Benz 190 W201 models with the 102962 M 102 engine. Confirm the exact vehicle model and engine code via the VIN or Benz’s official parts catalog to avoid fitment errors (e.g., poor sealing, ventilation failure). During installation, ensure tight connection with crankcase and intake system interfaces to prevent air leakage. Regularly inspect for signs of failure (e.g., hose cracking, hardening, oil seepage) and replace the hose immediately if faults are detected to maintain normal crankcase ventilation.
