PCV / Vacuum Line

[Bmak18]

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!)

When I owned my prelude, I did it once a year. I always did it right before I changed the oil, and changed the spark plugs (if you use the sea foam through the PCV valve)

Here is where I got all my information before I started doing it. (Sorry it's not kia related, but it might help you out)

My biggest thing is locating the actual hoses. I just replaced my plugs and oil a bit ago, only have 40,000 miles. Always used in the gas tank so i might ask the dealer where theyre at
