Hi, my touran is leaking from the crankcase breather hose, replaced with a new Febi part, and still does it. is this a big problem? makes the bottom of the engine look like its leaking badly over the period of time. there is a small O ring inside the hose, but i thought new part would stop it, but it did not. whats the way forward with this? its BKC engine 1.9 tdi. thanks
