Metzger Crankcase Breather Hose

The Metzger 2380002 crankcase breather hose is a precision‑engineered component designed to maintain optimal engine breathing and protect the internal oil system of BMW vehicles. It serves as the critical link between the engine’s crankcase ventilation system and the external atmosphere, ensuring that blow‑by gases are safely expelled while preventing contaminants from entering the oil.

Key Features

• High‑Quality Material: Constructed from durable, flexible rubber reinforced with a robust inner lining to resist abrasion and chemical degradation.
• Exact Fitment: Engineered for BMW models such as the E36, E39, E38, Z3, and other series, guaranteeing a seamless installation without modification.
• Optimal Length & Diameter: The hose length is calibrated to match OEM specifications, preventing excessive slack that could lead to kinks or air leaks.
• Secure Connection: Equipped with reinforced fittings and a secure sealing mechanism to maintain airtight integrity over the vehicle’s lifespan.

Installation Overview

Replacing the crankcase breather hose is a straightforward procedure that can be completed in under an hour. Follow these steps for a flawless fit:

1. Disconnect the battery: Safety first—ensure the vehicle’s electrical system is de‑energized.
2. Locate the existing hose: It typically runs from the crankcase breather valve to an external vent or a designated outlet on the engine block.
3. Remove the old hose: Carefully detach the fittings, noting their orientation for proper reassembly.
4. Attach the new Metzger hose: Slide the reinforced fittings onto the valve and outlet, tightening securely to avoid leaks.
5. Verify alignment: Ensure the hose is free of kinks and that all connections are tight before reconnecting the battery.
