Moin people, have today freed my X25XE from its intake system. Since the left valve cover or its seal has been renewed. I have seen this. In the intake area between air filter and throttle valvehttp://img264.imageshack.us/img264/8710/12004043.th.jpg throttle valvehttp://img812.imageshack.us/img812/2975/30823942.th.jpg Have also yellow mucus on the oil cover. However, the ZK seals are to be excluded in my opinion. CO Test was i.e., no cooling water consumption, no pressure in the cooling system, no dirt in the compensation tank, no engine problems. The valve cover was also normally dirty, so only with oil, the yellow mist is only at the highest point in this case the oil cover is. Can it be that the intake area or luf filter and DK and is able to ring water there? These amounts seem to me a lot for condensity. Thank you in yours.
