[QUOTE="SRAD97750, post: 192273, member: 425"] If you didn't do the measurement, then you are not certain of your first statement. 'Ring end gap' shows how well the ring fits the cylinder. If this measurement is off by much, if could be the source of the compression loss. When this measurement is out of spec and it's a new ring, then the cylinder needs to be bored to the next size, and the next size piston/ring installed. Typically +0.5mm at a time. -BIG DAN:thumb: [URL]https://www.youtube.com/watch?v=ViEjQ7B1uM8[/URL] [MEDIA=youtube]ViEjQ7B1uM8[/MEDIA] [/QUOTE]
