2122541 Crankcase Ventilation Oil Separator Fit D13 Engine FH FM FMX Heavy Duty Truck Aftermarket Replacement Part

OE 2122541 Crankcase Ventilation Oil Separator is exclusively matched with heavy-duty trucks equipped with D13 engine FH FM FMX series. It cannot fit other engine or truck series.

Produced following OEM original dimension and performance standards, the internal multi-layer coalescing filter efficiently separates oil mist from crankcase blow-by gas. It lowers engine oil consumption, avoids turbocharger contamination and extends engine service life. All pipeline ports, mounting lugs and sealing surfaces are identical to original factory parts for direct bolt-on installation without any modification.

The separator housing is made of high-temperature resistant material with durable long-service filter element, well adapted to severe long-haul driving conditions. It is an ideal replacement for clogged, leaking or worn original separators during engine maintenance. Please confirm your engine and truck model with sales before placing orders.
