Excessive oil WILL NOT cause a crosshatch to disappear. Too tight of ring gap, or incorrect skirt clearance will. OR the crosshatch wasn't deep enough, and didn't last through ring seating.

Unless the drian is plugged, or somethings creating excessive pressure. Im sure im not the only one that's seen a kohler blow the dipstick out. I respectfully disagree about too much oil not wearing the crosshatch. When the oil gets burnt in the combustion chamber it can lead to a gritty paste that will act as sandpaper in the cylinder. Like I said before, regardless of all the theories I would disassemble it and go over every piece to find the cause, I do agree that ring fit and skirt clearance could be a cause but I was just throwin out an alternative idea.
