Hi, my C4 GP II (Bj2016 BlueHDI 120) has blessed the time after a holiday trip. The timing belt is torn and I have meanwhile removed the engine and looked at the whole thing more closely: the valves still look, however, the camshaft is turned, and on the piston one sees clearly the prints. The ZK was so under tension that 4 screws could not be removed. Here I had to drill out the screw heads… I needed some swarm intelligence: Do you think an exchange engine would be useful or rich new ZK+Ventile+Nockenwelle?
