• Vacuum leaks at the crankcase ventilation circuit
• Improper crankcase ventilation flow
• Oil vapor contamination in the breather hose
• Emission control issues related to a failed breather hose

Installation Notes

Verify the hose routing against the vehicle’s intake manifold and crankcase connections before installation. This part is molded for the listed applications and uses two hose connectors with one branch, so correct orientation matters during replacement. For Mercedes-Benz S320, C280, C36 AMG, E320, and SL320 applications, confirm the existing hose path and connection points match the listed notes.

Quality Assurance

URO backs this crankcase breather hose with a 24-month unlimited mileage warranty. The replacement design is intended to restore crankcase breather function after OE hose failure, and the material selection supports resistance to heat and oil vapor exposure. This part cross-references VAICO V30-0669 for the same application.
