We compared my pistons with Nick's who did a tame break-in and the difference in ring seal was substantial! We both had over 2500 miles, but mine were in much better shape.

Mine that were broken in hard had very little discoloration below the first ring and nothing below the second. Nick's had substantially more below both rings. We could probably take some pics if they are still sitting in the box beside Cory's tool box.


More or less what this page says

Changed the oil/filter at 100mi and will do so again at 1000mi.
Were those mine? I tried to break my car it gently after the rebuild and I had oil consumption problems. So this time I beat on it and it's still been pulling a little down but not like before.
