Words from Blackstone from last sample: "cylinder-area metals have increased quite a bit. We expect high metals during wear-in, but things should generally improve -- these increases could show a problem with pistons, rings, and/or cylinders. It's possible the increases are due to running rich, but we can't say for sure if that's the case or not. Test compressions, borescope, and check back."
