Hello, would like to hear your opinions on the following compression values. I also had a compression measurement carried out on my car, a VW Polo, built in 2010 as part of the customer service. Simply because I was interested in it. everything was done by a free workshop. So and now a few more data: VW Polo, built in 2010, 1.4 l suction gasoline engine, 86 hp. Engine identification letter CGGB mileage 34739 Compression values: cylinder 1: 12.5 bar cylinder 2: 13.5 bar cylinder 3 : 12,5 bar cylinder 4: 13,5 bar The master thought everything was still fine. But would still like to know your opinion about it. Thanks for your answers and opinions.
