ok on my civic i have cold air intake and the breather hose for the oil that comes from the intake seems to be working backwards. the hose is transparent blue so i can see that oil has been going through it into my intake and i think this is wrong but i would like a second 3rd, or maybe forth opinion on it. i had to take off the intake to work on something and when i looked inside the intake tubing there was oil.....wtf? what is causing this and is it suppose to suck oil into the intake?

thanks
