2139831 2733439 Crankcase Ventilation Oil Separator Fit Scnia NTG DC9 DC13 XPI Engine Heavy Duty Truck Aftermarket Replacement Part

OE 2139831 and 2733439 Oil Separator-Crankcase Ventilation is specially designed for heavy-duty trucks with Scnia NTG DC9 and DC13 XPI engines, not compatible with other engine platforms.

Produced to match OEM dimensional and performance standards, the internal multi-stage coalescing filter efficiently separates oil mist from crankcase blow-by gas. It reduces engine oil consumption, avoids turbo contamination and extends engine service life. All inlet/outlet ports, mounting lugs and sealing surfaces replicate factory specs for direct bolt-on installation without modification.

High-temperature resistant housing and durable filter media adapt to harsh long-haul and heavy-load working environments. Ideal replacement for clogged, leaking or damaged original separators during routine engine maintenance. Confirm engine model and truck generation with sales before purchase.
