22877307 Crankcase Ventilation Oil Separator Fit D13 Pre-Alfdex Engine 2008-2013 Heavy Duty Truck Aftermarket Replacement Part

OE 22877307 Oil Separator-Crankcase Ventilation is exclusively designed for heavy-duty trucks equipped with D13 Pre-Alfdex engines produced from 2008 to 2013. This unit cannot be matched with other engine generations or vehicle models.

Manufactured in full compliance with OEM size and performance standards, the built-in multi-stage coalescing filter effectively removes oil mist from crankcase blow-by gas. It lowers engine oil consumption, prevents turbocharger fouling and extends engine service cycle. All inlet and outlet ports, mounting supports and sealing planes are identical to factory stock parts, enabling direct bolt-on installation without trimming or adjustment.

The housing adopts high-temperature resistant engineering plastic, paired with robust long-life filter media to withstand rigorous long-distance driving conditions. It serves as a perfect replacement for blocked, leaking or defective original separators during engine overhaul. Kindly verify your engine model and production year with sales before checkout.
