21679517 — Crankcase Ventilation Separator Voe21679517 Voe21975959 For Volvo Engine D11 Truck A45G A60H A30G A25G

This crankcase ventilation separator is a critical component of the engine's emissions control system, designed to remove oil mist from the crankcase gases before they are recirculated. It ensures that only clean air is returned to the intake, preventing oil contamination and maintaining engine performance. A failing separator will allow excessive oil vapor into the intake system, leading to increased oil consumption and potential exhaust smoke.

Installation & Application Notes

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.

Failure Symptoms

Initial signs of a failing separator include a slight increase in oil consumption and a faint smell of oil in the exhaust. If left unaddressed, the separator can become completely clogged, leading to excessive crankcase pressure and potential oil leaks from gaskets and seals. Continued operation with a failed separator risks significant oil loss and internal engine contamination.

Installation Tip

Ensure the mounting surface is perfectly clean before installing the new separator to achieve a proper seal. Do not overtighten the mounting bolts, as this can crack the housing.

Service Note

Inspect the crankcase breather hoses for any signs of clogging or damage during replacement.
