METZGER 2380005 Engine Blocks

METZGER 2380005 Engine Block Breather Hose

The METZGER 2380005 is a high‑performance, flexible breather hose designed specifically for the crankcase ventilation systems of BMW engines. It serves as an essential component in maintaining optimal engine pressure balance and preventing oil vapor contamination.

Key Functional Features

• Crankcase Breathing: The hose connects the engine block to the vehicle’s breather system, allowing excess crankcase gases to escape safely while preventing harmful vapors from re‑entering the oil.
• Flexible Construction: Made from durable, high‑temperature resistant elastomer, the hose flexes easily around mounting brackets and other components without compromising integrity.
• Secure Fitment: Equipped with a standardized connector that mates snugly to the engine block’s vent port, ensuring leak‑free operation even under vibration.
• Temperature Tolerance: Rated for continuous use up to 200 °C (392 °F), it withstands the high temperatures typical of modern internal combustion engines.
• Chemical Resistance: Resistant to oil, fuel vapors, and coolant, guaranteeing longevity in harsh engine bay environments.

Compatibility Overview

The METZGER 2380005 is engineered for a wide range of BMW models. It fits the following series and specific variants:

• BMW Série 7, Série 3, Série 5
• BMW Z3, Z4, X3, X5
• Specific model years: E36, E39, E46, E65/E66 (7 Series), X3, X5, Z3 Roadster, and others.

Because the hose is a universal fit for the crankcase vent port, it can be used on both front‑left and front‑right mounting positions depending on vehicle configuration.

Installation Guidance

1. Preparation: Clean the engine block vent area with a solvent to remove oil residue. Ensure the hose connector is free of debris.
2. Positioning: Align the hose so that its connector mates flush with the vent port. Avoid twisting or kinking the hose during placement.
3. Securing: Tighten any retaining clips or clamps as specified by the vehicle’s service manual. Verify that the hose is firmly seated and free from movement.
4. Verification: After installation, perform a pressure test to confirm there are no leaks. Check for proper venting during engine start‑up.

Maintenance Tips

• Inspect the hose annually for signs of wear such as cracks, bulging, or discoloration.
• Replace immediately if any damage is observed to avoid crankcase pressure buildup.
• Keep the hose away from sharp edges and excessive heat sources that could degrade the elastomer.

Benefits of Using METZGER 2380005

• Engine Longevity: Proper crankcase ventilation reduces oil oxidation, extending engine life.
• Emissions Control: By directing vapors away from the combustion chamber, it helps meet stringent emission regulations.
• Reliability: The robust construction ensures consistent performance across a wide temperature range.
