Hello in you round, don’t know any more. The problem: When starting up and only with warm engine, my “Susi” releases blue smoke. Temperature is about 80-85?. Is also only a short smoke bath and then is good. Ruckle or bad performance it does not. On the contrary. oil consumption is about 1l/1000km. Presumably: I first thought about the thermostat, because the display was crawling around for a while at about 70? and I had the feeling that the fans don’t start. Furthermore, the cooler is partly relatively cold, while the engine is quite hot. That the engine pushes the oil into the engine room due to the lack of cooling, the oil. Hmm………… after studying various threads in different forums, I’m not more sure. Can one help me? Thanks already. BP
