lol, oh god... You have to remove the head.. And if the motor spun rod bearings then the block needs to be cleaned, decked and checked for damage on the cyl walls.. Needs a new crank shaft or needs to be ground and cleaned pulling the plugs out in it and used undersized bearings.. Head needs to be decked, new head gasket. You can not pull the rods and pistons out through the bottom.. They have to be removed from the top.. And since it spun a bearing you have metal contaminates all throughout the engine.. Why am I even wasting my time..
