I was doing some research on how to further clean my engine and have gotten synthetic oil changes, used SeaFoam with the gas and oil, but i have also found you can run SeaFoam through the "PCV" or the Vacuum Line that runs through all cylinders, usually the brake line. I am wondering if anyone has done this and or where those are in the engine compartment. Or any other ways to cleanse the engine! (Same engine as the 2011, thats why im posting here!)
