Hello all, I suppose that I meet here numerous experts who can help me with my problem. after the winter break 8ca. 3-4 months) I started my vehicle (560 SL from 07/86). The engine ran quite unevenly. also a ride of about 10 km did not change anything. The checked candles were fine. Also the ignition cables were not nailed by an untier. Below the disassembled air filter housing I discover two thin hose lines, which pass through one side There was a small round can on a line. For more information see photos. Can someone tell me what function these lines have and if their damage can be caused by the unround motor run. For your efforts I would like to thank you already in advance. Greeting and stay healthy. Günter
