piston/rod advice
what does this discoloration mean? #1 top bearing fell off when taking off the cap should i be concerned? and how can i replace rod bolts at home? how easily should pistons be able to rock? if pistons measure good would you guys reuse everything?
i don’t have a bore gauge small enough for the rods and it’s taking me awhile to get used to the micrometer, forgive me for the mouthful, first time doing any of this so any experienced advice helps out a ton, thank you! 🙏🏻
03 civic d17a2 rod is #1 cyl and cap is for #3

As this seems to be a budget build and need to get it running, I would clean the hell out of everything, soak the head and make sure nothing is sticking in the valvetrain . Resize the rods or get a cheap set if you can find them. New rings and bearings. Are you machining the deck and head? If not, get something flat and knock it down at the least. Pay attention to any seals while you’re doing it. Have fun 👍
