Vaico V30-1380 Engine Crankcase Breather Hose - Valve Cover To Intake

Mercedes-Benz Crankcase Breather Hose

The Vaico V30-1380 engine crankcase breather hose routes blow-by vapors from the valve cover to the intake manifold on select Mercedes-Benz V6 and V8 applications. Built for the full-load crankcase ventilation path, it supports proper crankcase pressure control and clean vapor routing in the emission control system.

VAICO product line components are developed for European vehicle service needs, with application-specific dimensions and OE-style fitment for direct replacement work on Mercedes-Benz models.

Detailed Description

This Vaico crankcase breather hose is used in the valve cover to intake manifold ventilation path on many Mercedes-Benz platforms, including E-Class, S-Class, ML-Class, CLK-Class, SL-Class, and AMG variants. The hose dimensions and intake manifold fitting position support replacement of the original breather line where crankcase vapors are routed back into the intake stream. This part cross-references Gates (e.g., 33946, EMH188) for the same application.

Compatible With Mercedes-Benz applications such as SLK55 AMG, G500, ML500, E500, S500, and C320, this V30-1380 hose is a direct-fit service part for vehicles listed in the fitment data. It is also referenced under V30-1380 when searching for Mercedes-Benz crankcase breather hose replacement, valve cover to intake hose, or full-load crankcase ventilation hose.

What It Helps Address

• Cracked or hardened crankcase breather hose material
• Oil vapor leakage at the valve cover to intake connection
• Unstable crankcase ventilation routing
• Vacuum-related drivability issues caused by a damaged breather line
• Emission control faults tied to crankcase ventilation flow

Installation Notes and Tips

Verify the hose routing against the existing valve cover to intake manifold path before installation. Confirm the fitting position and dimensions match the original part, especially on Mercedes-Benz V8 and V6 engines where routing can vary by model year. Inspect adjoining connectors and nearby ventilation components for wear, oil saturation, or brittleness before completing the repair.

Quality Assurance

Vaico offers application-specific replacement parts for European vehicles, and this hose is cataloged for direct fitment on the listed Mercedes-Benz models. Use the part number V30-1380 to confirm application details during ordering and service lookup.
