Bore Gauge Help

No. Once the ridge is removed, that part of the cylinder will NOT be standard size any longer. The RIDGE itself IS the standard diameter. However, the ridge is too narrow to get a good measurement on. I always just go down to the bottom of the bore,beyond the ring travel in the bottom of the cylinder like the book says and take the measurement there. There's probably still cross hatch down there. Compare measurement with the measurement you get about .500" of an inch below the ridge. This will be where the wear is greatest, again, like the manual says. You do have an engine manual, right?
