I found a cracked hose on my engine but i have no clue what is it for. When you take the plastic covering off and look at the engine from the front of the car it is on your right, in a back. It is veri short, about 2-3 inches and it is red color. Right above there is blue one which is much longer. Also wwhen you look at it, it is to the right from the TB, actually, there is 2 black round things, one with ruber covering, so the one where my hose is runing from is under those two. it is also round and positioned horizontally, but its not black but metal, kinda silver color. Am I clear? Thanks....maybe I'll be able to get a picture
p.s. the way the car drives is normal, no diference
