recently rebuild the let but time for steel rods. pistons are 0.5mm oversize so block was rebored a year or so ago and compression is spot on. will i get away with rings and a hone or is a rebore always advisable no matter what circumstances. dont wona be passing oil after a couple of months

as long as the bores are unmarked and still round (not likley to have gone oval but worth checking) then a hone and new rings is fine

why? mark up the piston as to which bore it came from, maybe someone will offer great insight into why this is a bad idea, but if ive taken pistons out and there hasnt been a problem i just put them back in the cylinder it came out of and thats that. i will be wrong though
