Thanks for the info. Still not fully comprehending though.
Haven't the vast majority of these cases been isolated to the rear driver's side area (7&8)? Wouldn't that still suggest a (cooling?) problem in this area?
Also, it is my understanding that cylinders are honed straight, but that pistons are somewhat cone shaped (larger at the top) to accommodate heat expansion. Is this not the case?
Has this been affecting all pistons/cylinders?
