Where do the 2 breather hoses oil cap go on a 205 gti?

There are two possible locations for the two breather hoses on the oil cap of a 205 GTI - the air filter housing and the brake servo. They are both connected with metal pipes. Check whether the pipe to the brake servo is connected on the engine block - it connects to the pipe running from the rocker cover. Alternatively, it may be connected directly to the rocker cover.
