Hello, I have an Omega B 2.2 16V Caravan Bj.12.2002 First of all I have to say that I am really enthusiastic about this forum. Fast and mostly very experienced help, my compliment to all. My problem is the following, for 3 days my car consumes about 300 kilometers a half liter of water which does not appear visible again 🙁 and when I start it in the morning it runs completely unevenly, but what is done after approx. 50 to 100 meters. Also I notice that sometimes makes itself noticeable at approx.3000-4000 rpm a jerking. My fear is the ZKD where my nightmare would be a defect ZK. What makes me mean is that neither white smoke, bubbles in the compensation tank, or water in the oil makes noticeable. My question to you is if you have any other idea what could play out there. I thank you already for your answers. Greeting Wetzi
