4974922 Crankcase Ventilation Oil Separator CCV Breather Heavy Duty Truck Engine Aftermarket Replacement Part

OE 4974922 CCV Crankcase Ventilation Oil Separator is manufactured to meet OEM standard specifications for heavy-duty vehicle engine maintenance.

The built-in multi-layer coalescing filter effectively removes oil mist from crankcase blow-by gas, reducing engine oil consumption and stopping oil residue from polluting turbocharger assemblies, which greatly extends engine service life. All mounting points, pipeline interfaces and sealing surfaces are consistent with original factory components, enabling direct bolt-on assembly without cutting or refitting.

Constructed with high temperature resistant housing and long-life filter media, this breather separator performs stably under heavy load and long-distance transport harsh environments. It is the ideal replacement for blocked, leaking or aging original CCV units during engine overhaul. Please provide complete engine model information to sales staff for compatibility confirmation before ordering.
