Hallihallo, I had asked the question here some time ago whether it is possible to see whether increased oil consumption is due to the valve shaft seals or the piston rings. I have now such a guess, because I noticed that it is a little blushing at the cold start. It is not much, and wg. of synthetic oil also not really blue, but nevertheless clearly recognizable as burnt oil. Now I am something in the grinder. Oil consumption (at least with me already about 1 liter on 23 00-2500km) can come from both. The bluish actually only comes at the start, which rather speaks for VSD, because the oil seems somehow to seep into the combustion chamber. Since with standing cylinders in principle the piston rings dissipate. During the ride blazes nix, but the oil consumption is there, which can of course also be due to worn rings. So, what then? Performance is also lacking him by the way. He creates with effort 190 tacho instead of the specified 205. My Vorbes itzer doesn’t seem to have handled the engine very carefully, otherwise I can’t explain this with this comparatively ridiculous mileage of about 224tsd… Anyway, any ideas?
