Hello, as the title already shows, I have to complain to our Omega about the oil leak shown in the pictures. When I followed this for the first time, I had the hope that it had leaked due to the unscrewed oil pressure switch. Since I put on the oil pressure switch and removed all recognizable oil residues with kitchen cloths, I can find again oil leak after a short period of operation. So that I do not have to describe the “founding point” in a complicated way In principle, the oil also seems to reach the bottom of the alternator, because the paper cloths are smeared with oil after contact with this area of the alternator. I want to rule out that it leaks further up from the valve cover seal. Although I had already diagnosed a slight leak here, however, the exit seems marginal. By the way, the car and engine have run a little less than 80,000 km and are 12 years a Where could the exit point be? Rejoice me about tips. Greeting Hansi
