VOE21679517 — Crankcase Ventilation Separator Voe21679517 Voe21975959 For Volvo Engine D11 Truck A45G A60H A30G A25G

This crankcase ventilation separator, also known as a PCV (Positive Crankcase Ventilation) system component, removes oil mist and contaminants from the crankcase gases before they are recirculated into the intake system. It is designed to efficiently separate oil from the air, maintaining proper crankcase pressure and preventing oil fouling, unlike a clogged or failed separator which allows excessive blow-by to enter the engine. Operators may notice increased oil consumption, blue smoke from the exhaust, or oil leaks from seals and gaskets when this component malfunctions.

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

Early signs of a failing crankcase ventilation separator include a slight increase in oil consumption and potentially a faint smell of oil in the engine bay. If ignored, the separator can become completely blocked, leading to excessive crankcase pressure that forces oil past seals and gaskets, causing visible leaks and blue exhaust smoke. Continued operation with a faulty separator can result in significant oil loss and potential damage to engine components due to inadequate lubrication.

Installation Tip

Ensure the mounting surfaces are clean and the O-rings or seals are properly seated before tightening the separator housing. Avoid overtightening, which can crack the plastic housing or damage the seals.

Service Note

Inspect the crankcase breather hoses for any signs of blockage or damage, and check engine oil seals for leaks.
