Hello dear people. I was here the other day and had a few questions for battery, now I have a real problem. The OMI was in the workshop to exchange the clutch. Now he licks ÖL. My FOH told me that the oil tank has a hair crack and that a new one should cost around 300 €!!! I suspect that the apprentice, the oil drain screw has tightened too tight and now a crack has arisen on the socket.I can not prove this and must have a new one installed. My question therefore, can one also take a used one? And how can I try that the FOH does that on kulanz, since the damage has occurred after repair. I am desperate.! Thank you
