VAICO Crankcase Oil Separator

The VAICO crankcase oil separator (also called an oil separator, oil trap, or crankcase breather separator) is part of the crankcase ventilation system. It separates oil mist from the blow-by gases that build up inside the engine. The cleaned gases return to the intake, and the separated oil drains back to the engine.

Key Features:

• Separates oil from crankcase blow-by gases to help keep oil out of the intake tract
• Helps maintain correct crankcase pressure and supports emissions-related ventilation function
• Replacement part for BMW applications
• Made to meet OE specifications for fit and function
• Backed by VAICO's quality testing and engineering

A worn or clogged oil separator can cause oil consumption, rough idle, and ventilation faults. Replacing it helps restore proper crankcase ventilation. VAICO is part of the Vaico/Ferdinand Bilstein group. It supplies replacement parts for European vehicles. Choose the child item that matches your application.
