So before anyone criticizes me and tells me I'm stupid let me just lead with the statement that I know the basics about vehicles and working on them (oil change, brakes, bulbs etc etc) and I'm learning as I go. So when I initially bought my gti I wanted to do all the work myself to learn the car inside and out and use the forums for my resources. Anyways, I bought the bsh race intake from the previous owner, who I now know is an idiot, and he didn't get the cbfa intake version. He installed it for me and showed me what everything was and where it goes yadayada. When it came to the breather hose, he said "don't worry about this you just leave it". It has no filter on it and is currently just tucked under the heat shield box of the intake filter. I've been looking into the unitronic filter recently and saw the same hose with a small filter on it and put two and two together and I'm afraid I may have damaged the vehicle internally. I'm ordering a filter for it asap but I just want to know how screwed I am.
