I need help quick to ride in the snow. I have an '01 DS and the hose that attaches to the bottom right of the engine and then runs up the right side of the radiator, has come off of whatever it was attached to at the top. It looks like an oil hose but for the life of me, I cannot find what it had been attached to at the top. What am I supposed to be looking for? Thanks

 

That is your breather hose for the crank case is gos to your air box tube
