2002 lq4 from a 2500hd
it looks like its been sitting outside for a few years and water worked its way in to some of the cylinders and sat there. do you think it needs to be honed out/rings replaced or what? how smooth do the cylinders need to be? anything else that should be checked on an engine like this?
the pics are from after me spending a good while cleaning the pistons and walls with degreaser and oven cleaner and removing carbon buildup.
