Good evening to all have thought of posting here once, in the hope someone might have had the error already. Have a Renaul Clio 2 bj 2000 . Unfortunately the engine runs partially white only on three pots. So ignition system tested, sparks was there. Sprit also comes. then I tested compression with the following values. CALTS STAND Zyl 1 : 4.5 bar afterwards few drops of oil pure , it comes to 7 bar Zyl 2-4 are all in the green area. approx. 11 bar after that I tested it in warm condition , because if the engine operating temperature it runs “almost” round. Warm condition Zyl 1 8.5 bar with oil almost 12 bar. Think that should be the piston rings. It has now run 149 000 km. Had someone experience with the engine? Thank you for your answers. Greetings Warm condition
