Rein ABH0279 Oil Separator Box for Volvo

The Rein ABH0279 Oil Separator Box is an OE-quality replacement part designed for Volvo vehicles. Also known as an oil trap or PCV breather box, this critical component separates oil mist from blow-by air in the engine crankcase, draining clean oil back to the oil pan while allowing filtered air to return to the engine intake.

Key Features:

• Direct replacement for Volvo OEM part number 3501160
• Durable black plastic construction designed for long-term reliability
• Prevents crankcase pressure buildup that can cause oil seal failure
• Engineered to OE specifications for precise fit and function
• Manufactured by Rein Automotive, specializing in European vehicle parts since 2007

Important Installation Note:

O-rings are sold separately and not included with this oil separator box. Volvo O-ring part number 949659 is recommended for proper installation.

Why Regular Replacement Matters:

Over time, sludgy oil deposits accumulate inside the separator box, particularly with neglected oil changes or frequent short trips in cold weather. A clogged separator restricts blow-by ventilation, causing pressure buildup that can rupture engine seals and gaskets. Regular replacement of the oil separator box and associated PCV hoses every few years is recommended as preventative maintenance.
