I can't believe I had never heard of this, but I have read scotch brite usage can ruin an engine in only a few miles. I used a combination of a scraper, a wire wheel on a drill, and a scotch pad by hand to clean the head surfaces, intake surfaces, block, and somewhat the tops of the pistons. Used a vacuum cleaner to remove all of the debris I could see.I'm feeling pretty down after coming across a few articles linking scotch brite to engine failure. Should I not even bother reassembling and just have the engine rebuilt at this point? Is there also any way to clean out debris that may have gotten down between the piston and the cylinder wall or should I not worry about that? Any honest advice would be appreciated. Not feeling very confident about reassembling at this point. I have the oil pan off as well if that makes any difference.
