BMW M57 Crankcase Ventilation Adapter

BMW M57 Crankcase Ventilation Adapter – Oil Catch Tank Conversion

The BMW M57 Crankcase Ventilation Adapter is designed for custom engine builds where the factory crankcase ventilation system is no longer in use – for example, after trimming the valve cover to gain additional clearance in a tight engine bay. This adapter routes crankcase gases directly to an external oil catch tank, ensuring optimal engine breathing and reduced oil contamination in the intake system.

Purpose & Benefits

• Provides a clean and efficient solution for crankcase gas evacuation
• Ideal for engine swaps and performance builds with modified valve covers
• Prevents oil mist from entering the intake system
• Improves engine longevity under high load and boost conditions

Design Features

• Custom-fit for BMW M57 engines
• Durable, high-quality materials for long-term reliability
• Supplied with a connecting element for straightforward installation

Installation Notes

Designed to work seamlessly with an external oil catch tank setup. Perfect for M57 engine swaps where space optimization and clean crankcase ventilation are critical. Compatible with both stock and high-performance configurations.
