Application Details

This engine oil separator is built for 2009-2016 Volkswagen Jetta, 2015 Volkswagen Golf SportWagen, and 2012-2015 Volkswagen Passat. If you are searching for a Volkswagen Jetta oil separator replacement, a Volkswagen Passat engine oil separator, or a 2015 Golf SportWagen crankcase ventilation part, Dorman 264-903 matches the listed applications.

The separator routes oil vapor from the crankcase ventilation system so less oil reaches the intake. That helps reduce intake contamination and valve deposits on engines that are sensitive to oil carryover. Dorman 264-903 is a direct-fit style replacement for service work where the original separator has worn, cracked, or become restricted.
