The Volvo D13 Oil Separator — Genuine (22877306) is the original OEM crankcase ventilation filter for Volvo D13 engines. The oil separator removes oil mist from crankcase blow-by gases before they are recirculated into the engine intake via the CCV system. A clogged or failing oil separator increases crankcase pressure, causes oil consumption, produces blue exhaust smoke, and leads to oil contamination of the intake, intercooler, and EGR system. Regular replacement maintains proper crankcase ventilation and reduces emissions.

Q: Which trucks and engines does this oil separator fit?
A: Fits Volvo VNL trucks with D13 engines. Genuine Volvo OEM part number 22877306.

Q: How often should the D13 oil separator be replaced?
A: Volvo recommends replacement every 150,000 miles or as part of major service intervals — more frequently in hard-duty applications.

Q: What symptoms indicate a clogged oil separator?
A: Increased oil consumption, blue smoke from the exhaust, oil residue in the intake piping, elevated crankcase pressure, and oil leaks at seals and gaskets.

Q: Is this a genuine Volvo part?
A: Yes. This is the genuine Volvo OEM oil separator 22877306 — the same unit installed at the factory.
