Hello I’m just new here in the forum and I have a problem with my Calibra V6. The engine clacks quite loudly (but seems to be only on one cylinder) and it runs quite unevenly, especially in the stand hear and notice it extremely. That’s why I had a compression test done. Cylinder 1 = 14.1 bar Cylinder 2 = 10.1 bar Cylinder 3 = 12.1 bar Cylinder 4 = 11.8 bar Cylinder 5 = 12.9 bar Cylinder 6 = 12.0 bar In my opinion, the loud clacking comes exactly from the Zyli I’m actually typing on the valves myself, is that possible? The workshop said that it’s probably not the piston rings. What do you think of the compression values at all, are all quite far apart. Hope you can help me. Thanks in advance
