Hello! With a friend already for the 2nd time at a Lupo 1.0 ALL (approx. 180,000km) the camshaft and some cup plungers are worn out, one has already a hole. Before < 10,000km it was renewed already with some cup plungers!How is the camshaft or their cams lubricated? In photos I could not recognize this so far. For the NW-storage it probably comes from the bottom of the bearing bells, and for the cup plungers sideways from the cylindrical bores/seats. Thank you, Dieter
