This is a crankcase oil separator for Volvo D13 engines, designed to remove oil mist from the crankcase ventilation system and return it to the oil sump. It is manufactured to OEM specifications to ensure effective separation and prevent oil contamination of the air intake, unlike a clogged separator that can cause pressure issues. Operators may notice increased oil consumption, engine oil leaks, or a 'check engine' light related to crankcase pressure when this component fails.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A clogged oil separator may initially lead to increased crankcase pressure, potentially causing minor oil leaks from seals and gaskets. If ignored, the system's efficiency will degrade, leading to higher oil consumption and potential oil fouling of the air intake system. The worst consequence is excessive pressure buildup that can damage engine seals and gaskets.
Ensure all ventilation hoses connected to the separator are clean and free of obstructions before installation. Do not overtighten the mounting bolts, as this can crack the separator housing.
When replacing the oil separator, inspect the crankcase ventilation hoses for cracks or blockages and check the engine oil level and condition.
