This breather is a critical component of the engine's crankcase ventilation system, releasing pressure and filtering contaminants. It is manufactured to Volvo's exacting standards, ensuring effective pressure regulation and preventing the ingress of dirt and moisture that can degrade engine oil. A clogged or damaged breather can lead to increased crankcase pressure, oil leaks, and potential internal engine damage.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A blocked breather may initially cause slight oil seepage around seals or gaskets due to increased crankcase pressure. If ignored, this pressure buildup can lead to more significant oil leaks and potentially damage internal engine components over time. Persistent high crankcase pressure can compromise engine seals and lead to costly repairs.
Ensure the mounting surface for the breather is clean and free of oil residue before installation. Do not force the breather into place; it should fit snugly without requiring excessive pressure.
When replacing the breather, inspect the crankcase ventilation hoses for any signs of blockage or deterioration.
