Piston/ liner question

[Rawze]

How much power was the engine set to? Mandated, de-mandated? etc.

hard to tell in the pic where on the piston it is cracked. Intake side? exhaust side?

I have seen carbon buildup do that too resulting in poor piston cooling in the skirt. Just saying.

The pattern on the liner could have been from before it failed, OR after, depending on the nature of the failure.

You can tell though, the piston was not being cooled evenly, nor did it have a nice spray pattern on shadow on it, but more like a partial.
