21975959 — Crankcase Ventilation Separator Voe21679517 Voe21975959 For Volvo Engine D11 Truck A45G A60H A30G A25G

This crankcase ventilation separator is a key component in managing engine blow-by gases, filtering oil mist before returning clean air to the intake. Manufactured to Volvo's high standards, it effectively removes contaminants, unlike a clogged or damaged separator that can lead to increased oil consumption and pressure buildup. Operators may notice increased oil leaks or a 'foggy' appearance in the air intake if this part is failing.

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

A failing crankcase ventilation separator may initially present as slightly increased oil consumption or a faint smell of oil in the engine bay. If left unaddressed, pressure can build, leading to oil leaks from seals and gaskets, and potentially impacting engine lubrication and emissions control.

Installation Tip

Ensure the new separator is correctly oriented to allow for proper drainage of separated oil. Do not force connections; they should fit snugly without excessive pressure.

Service Note

Inspect the crankcase breather hoses and the air intake system for any blockages or oil buildup during replacement.
