Not normal, but very common.

Mine was the same after less than 5k. Pistons very badly worn because of the long stroke and lose bore clearance. Wiseco's running a whopping 7thou clearance, which I'm sure didnt help at all.

I'm rebuilding and destroking.

Although my previous JE pistons in a different build didnt suffer the same problem. They did had some marks, but nothing worth worrying about and it had ran for around 10k before I destroyed it.

Does that piston use a support ring? Can't tell from the piston. Its an extra ring, goes in with the oil control rings.
