Hello, unfortunately I have the problem that my XC 90 oil burns. Sometimes it makes more blue clouds times less. The consumption is always the same constant. I have done a lot but so far unfortunately without success. – Oil trap removed and cleaned. – KGE membrane OE Volvo renewed – intake curvature dike renewed – Oil tub dismantled to control channel of the oil trap Unfortunately nothing brought a success. Does anyone still have an idea to narrow down the whole thing? I don’t like to pick up the whole engine to make everything new, then find out that didn’t work. Maybe or did who have the same problem? LG Christoph
