VAICO V20-1645 Crankcase Breather Hose with Expansion Tank

The VAICO V20-1645 is a high‑performance crankcase breather system designed to maintain optimal engine operation by efficiently removing excess gases and maintaining pressure balance within the engine’s oil system. Engine cooling, air‑oil separation, and pressure regulation are all achieved through this compact yet robust assembly.

Key Functionalities

• Crankcase Breather: Channels blow‑by gases from the crankcase to an expansion tank where they can be safely vented or recycled, preventing oil contamination and preserving engine longevity.
• Expansion Tank Integration: The built‑in reservoir accommodates pressure fluctuations caused by temperature changes, ensuring a stable oil environment.
• Air‑Oil Separation: A dedicated filter element within the hose separates moisture and particulates from the breathing air before it reaches the engine, protecting internal components.

Material Composition & Durability

The V20-1645 is constructed from premium silicone rubber, chosen for its exceptional resistance to high temperatures (up to 200 °C), chemical compatibility with engine oils, and long‑term flexibility. The hose’s inner lining incorporates a fine mesh filter that resists clogging while allowing rapid gas flow.

Compatibility & Fitment

This model is engineered specifically for BMW engines, covering a wide range of models including:

• 1 Series (E81/E82/E87/E88)
• 3 Series Touring (E91)
• E90/E92/E93 E‑Series sedans and coupes
• X3, X4, Z4, and other compact SUVs
• Various engine displacements from 2.0 L to 3.0 L inline‑four configurations

All dimensions are calibrated to match OEM specifications, ensuring a seamless fit without the need for additional adapters or modifications.

Installation Procedure

1. Disconnect the battery: For safety, always start with the vehicle’s electrical system isolated.
2. Remove the existing breather hose: Loosen clamps and detach the hose from the crankcase vent port.
3. Attach the V20-1645: Secure the new hose to the engine’s vent port using the supplied clamp, ensuring a tight seal.
4. Connect the expansion tank: Attach the hose’s opposite end to the designated expansion reservoir. Verify that all fittings are snug and free of leaks.
5. Check for proper alignment: Ensure the hose runs without kinks or excessive bends, which could restrict airflow.
6. Re‑connect the battery and start the engine: Observe the system’s operation; any abnormal noises or pressure readings indicate a need for adjustment.

Performance Benefits

• Enhanced Engine Longevity: By preventing oil contamination with blow‑by gases, the V20-1645 reduces wear on piston rings and seals.
• Improved Fuel Efficiency: A cleaner oil environment allows pistons to operate more efficiently, translating into better fuel economy.
• Reduced Emissions: Proper venting of blow‑by gases limits the release of hydrocarbons into the atmosphere.
• Consistent Oil Pressure: The expansion tank stabilizes pressure variations caused by temperature changes, maintaining optimal lubrication.

Maintenance Guidelines

The V20-1645 is designed for low‑maintenance operation. However, periodic checks are recommended to ensure continued performance:

• Inspect the hose and expansion tank for signs of wear or cracking every 12,000 km.
• Verify that clamps remain tight and replace them if corrosion is observed.
• Check the filter element inside the hose annually; clean or replace if particulate buildup exceeds manufacturer recommendations.
