Message: [QUOTE="golfer, post: 1100368, member: 266"] did you perform a compression test on the cylinders prior to pulling it apart?? the cylinder bores don't look like they've ever been bored or honed to me... I've seen 250k mile engines with dusted engines, & lowwwww compression that had good looking cross hatch...just piston to bore clearance that were too loose. so, while (visual) crosshatch doesn't mean anything... something is obviously not right. tough to see/read the numbers stamped on the pistons...what bore size are the pistons for? you'll need to pull the pistons out, measure them with a mic...then dial bore gauge the cylinders to see what kind of piston to bore clearance you have the amount of soot sticking to the pistons is generally indicative of poor combustion &/or poor piston ring sealing (and hence poor combustion).
