Renault Clio II 1.4 16v no compression

Hello together, My clio, which I have only had for about 2 months, showed the following problem abruptly last week: How if you had flipped a switch, it ran at once very tumbling and had no more full power. We tested the candles, the ignition coils of each cylinder, All sensors and the compression. At this we finally got stuck, cylinder 3 didn’t show up any more. So started to disassemble, under the valve cover was nothing really to be found I’m glad that I’m not driving a lot, I think the wear spot is limited. I think… Would it possibly do new piston rings? I’m glad about every hint. I’m very happy that I’m not going to be able to do this, but I’m glad that I’m not going to be able to do it. I’m glad that I’m not going to be able to do it. I’m glad that I’m not going to be able to do it. Greetings Eddy
