671's H23A1 Official Rebuild Thread

So i have another thread about removing the motor and i have recently decided to actually fully rebuild it instead of just replacing what needs replacing. so im starting this thread with a proper title and posting pics.

not entirely sure if this is the right way but lets try. if not i'll go check the stickys again for a walkthrough on how
picture before removing anything. fully stock except for the obvious aem short ram

Re: 671's H23A1 Official Rebuild Thread

heyyyy it worked. well heres the next batch. my progress so far. pics are a little bigger than i thought so forgive me for making you guys scroll

battery and tray, exhaust, radiator removed, cruise control gone, all wires unplugged (wanted to remove them so they wouldnt be in the way but the water pipe running along the back is getting in the way):


exhaust ports all look like this:


oh and i found this in the bottom of my radiator reserve tank:
WARNING! MAY CAUSE LOSS OF APPETITE. seriously it made my pregnant friend lose it. and thats a pretty big accomplishment in my opinion.

Re: 671's H23A1 Official Rebuild Thread

What are you plans for this rebuild? Just oem replacements? And you can resize your pics on photobucket man just use the edit feature.

Re: 671's H23A1 Official Rebuild Thread

Well some things will be oem and some things won't. Depending on what they are. I think most of my seals I wont bother with oem but as for bearings definitely. You have any recommendations? I'll stick with the original camshafts and crank. Unless I get a really badass job. Its not having any major problems. Just noisy valve train and a knock which I think is carbon but wont know for sure till I check the bottom end out.

Re: 671's H23A1 Official Rebuild Thread

I've never did a rebuild man. Honda motors are built damn well in my opinion and as far as I see it the only reason to go non oem is if you're going for more power.

Re: 671's H23A1 Official Rebuild Thread

Yeah I know what you mean. Im not too into going high performance since it's an h23. Unless I turbo it but that's a lot of time and money. I'll be seeing what's available and taking suggestions as well.

Re: 671's H23A1 Official Rebuild Thread

Does the nostril lights work? You might wanna consider getting the H22 head from the 5th gen in Lujan's for a future project. Good luck with the rebuild man.

Re: 671's H23A1 Official Rebuild Thread

you should throw some HIDs into the nostril lights, like 30000k, some green or pink or some ****, and wire them to a switch, otherwise id throw the nostrils back in... got your work cut out, but it will come along, good luck

Re: 671's H23A1 Official Rebuild Thread

Im only able to work on it on Saturdays. For the sake of the class. Found out the center main bearing was rotated. Possibly spun. So next im going to measure the journals and check the rod bearings.

Re: 671's H23A1 Official Rebuild Thread

now that i have time to load the photos

block:


head:


crank:


from left to right journals #2 and #3 were burned. as well as the cap on #3.
i dont think the bearing actually spun though. i think it just rotated a little bit. theres a little circle on the bearing surface where the oil hole was after the bearing turned. so i think it just stayed in place and blocked the oil.
also on the bottom of the block, there were the numbers "32233" etched into it. the "22" corresponds with the burned bearings so im thinking this motor might have been rebuilt before and those are the bearing sizes that were used. sound correct?

anyways, going to remove the crank then the pistons and measure everything this coming saturday. fingers crossed that i wont have to remachine the crank. is it possible to just get the burned part off with a strip of fine sandpaper or emery cloth? if the block is damaged then of course im just gonna forget going all perfect and put everything back together and see how long it lasts before it finally dies. give me some time to save up for an h22

Re: 671's H23A1 Official Rebuild Thread

The 32233 is stamped on the block from factory to designate the bore of the main journals. You use these numbers and the numbers stamped on the crank to pick out the correct sized bearing.

Re: 671's H23A1 Official Rebuild Thread

That's the thing. They aren't stamped. They're etched. Like with a cheap electric engraver

Hmmm, pics of the etching?



MAYYBEEE if it was rebuilt, the builder did indeed etch those numbers to remind himself of the clearances.

Re: 671's H23A1 Official Rebuild Thread

pulled the crank out. number 3 bearing slot is burned, but still straight and level




oh hello carbon -__-


crankshaft was too eaten up on number 3 to save it. ordered a reman from rockauto, should be here by tuesday, and i'll be ordering the bearings before the end of the week hopefully. from there on out it should be a breeze to get the rest of the stuff back together. hoping to have it driveable by my birthday :)
