22999818 21679517 Crankcase Ventilation Oil Separator Fit D11 MP7 Engine 2014-2019 Heavy Duty Truck Aftermarket Replacement Part

OE numbers 22999818 and 21679517 Oil Separator-Crankcase Ventilation are specially designed for heavy trucks equipped with D11 and MP7 engines made between 2014 and 2019, and cannot be applied to other engine models or year ranges.

Produced strictly following OEM size and performance standards, the internal multi-layer coalescing filter can efficiently separate oil mist from crankcase blow-by gas. It effectively reduces engine oil consumption, avoids turbocharger contamination and extends engine service life. All pipeline interfaces, mounting lugs and sealing surfaces are consistent with original factory parts, supporting direct bolt-on installation without cutting or modification.

The separator shell is made of high-temperature resistant material with a wear-resistant long-life filter element, which can adapt to harsh long-distance transport working conditions. It is an ideal replacement for blocked, leaking or damaged original separators during engine maintenance. Please confirm your engine model and production year with sales before ordering.
