Ensuring you are Ready for the Road Ahead™, the Dorman Oil Separator Repair Kit for Volvo is a direct replacement for the crankcase breather element. Featuring precise fit, function, and performance of OEM parts, this repair kit can offer cost savings, especially where the OEM only offers complete breather assemblies. The separator may fail on its own due to clogging, cracking, or bearing weight from aging, easily established by noise and vibration. Excessive oil mist from the gas outlet can also signal separator failure. This kit allows for the replacement of the separator without the need to replace the lower housing on the engine block. Dorman has a distinguished reputation in the heavy duty truck and trailer aftermarket, manufacturing a variety of parts for a complete repair. Through advanced engineering, Dorman successfully checks into today’s most common failures to figure out the why, ultimately delivering modern solutions that not only match OEM parts, but solve known issues.
