a short block i opened recently had some water sit in it, in the rear housing

rear rotor had some rusty build up, after cleaning it is heavely pitted i deemed them paper weight

the rear iron and intermediate iron have some staining on them, but are very smooth after using some degreaser and a very new shard razor blade to remove and sludge build up
i cant feel anything with my nails sliding them across, im assuming that they need to be lapped to be deemed usefull!
let me know
