Yes Jim, and worse. Its hard to tell from the picture but the amount of verticle scoring in that case could have screwed the pooch anyway. If it requires boring and new pistons letting it sit isn'y as important. The real problem can't be seen in a picture such as this or in person as the real problem is the rings rusting into the piston grooves, which will cause the galled results that look to have taken place there for a different reason.
