Re: G16 compression test
G16 are the same, should be in the 155-175 range. Do the test at WOT like Mike suggests, but I would make sure the valves are set correctly first ( four thousandths cold). If it's still low squirt a little oil in the cylinder and re-test. If the compression comes up you know you need rings, if not you may have a stuck or bad valve.........
