redark, the plunger is getting longer on + readings. Line honed sounds scary. the mains appeared to not have been messed with. Thanks for your input!looking at the numbers it looks like the block was line honed and the crank center line has moved up. that or it took a hit or got dropped. only question i have is on the direction of the numbers. when you say plus is the plunger in the indicator getting longer or shorter.
