Hello Together The Kummer chain does not tear off. Now I have a new problem since yesterday (the revised transmission is hardly a week old): It uses massive white bluish in the following situation: – engine warm – car stands for at least 3min with running engine – I give gas (no matter if little / strong) But during the ride you see nothing. If I stop, briefly turn the engine on 5’000 tours, you see nothing. It has to stand, and indeed something more than 1-2 minutes. I have read here a lot about valve shaft seals and so, but then I think he always has to smoke when turning up, but does not. Does this behavior provide an indication of possible other causes? Thanks for any tip, Ken
