I'm starting to think that this, besides the actual broken piston/rings, is kind of a blessing in disguise seeing how the bearings look. I think it must have been the fact that I just opened up, wiped down and dropped in the crank, rather than pulling the plugs and cleaning it thoroughly after reading about similar situations. Either that or there was some other debris somewhere in the block that neither I nor the engine guy cleaned. I bought the 'complete engine brush set' and cleaned everything I could get to... Oh well, lesson learned? Got a new set of stock size bearings coming and may wind up sending out the crank for polish if a quick check doesn't show that I can just do it myself. I was honestly surprised at the scratches and that conclusively tells me I missed something somewhere. I an theorizing that maybe the material that caused these scratches may have wound up clogging the first set of lifters, causing the noise from the get go? I will be pulling it apart to replace all the bearings. I know this is a tuner site, but who doesn't like checking out someone else's struggles, mistakes and, of course BROKEN STUFF?
