The MCT Oil Separator (replaces Volvo/Mack 22877306) is an aftermarket crankcase ventilation (CCV) filter for Volvo D13 and Mack MP8 engines. It removes oil mist from crankcase blow-by gases before they recirculate through the intake, protecting against oil fouling and excess consumption. Built to match OEM flow, filtration efficiency, and mounting, it delivers genuine-equivalent performance at a lower cost — ideal for fleet and high-mileage maintenance.

What does the oil separator 22877306 do? It centrifuges oil droplets out of crankcase blow-by gases, returning oil to the sump and venting clean air to the intake, which controls crankcase pressure and reduces oil consumption.

Does the MCT separator fit both Volvo D13 and Mack MP8? Yes. Part 22877306 is shared across Volvo D13 and Mack MP8 engines, so this MCT replacement fits both.

Is MCT a good alternative to genuine Volvo? MCT is a quality aftermarket brand built to OEM form, fit, and function. It offers the same CCV performance as the genuine 22877306 unit at a lower price — a practical choice when factory branding isn't required.

What are the symptoms of a failing oil separator? Rising crankcase pressure, increased oil consumption, oil in the intake or CCV hoses, blue exhaust smoke, and seal leaks caused by pressure buildup.
