I bought a b18b1 bare block. the block is sleeved with benson light sleeves (so thats what the previous owner said) the problem is that one of the sleeves has some pretty bad scratches. the wrist pin came loos and scratched up the sleeve. the sleeves are in 81.00 mm bore. my question is can i buy only one sleeve? can i bore it out to say 84.00mm? I will have pics up tomorrow to help out.

btw its also missing one main cap. can i buy one from another block and install it without having any problems?

 

you dont need to resleeve to fix that. just have a good shop bore it out to whatever size piston you want to run - at least 81.5mm

 

well i took it to a machine shop and they said it couldn't be fixed. now he only looked at it and told me that. the scratches are pretty deep.

 

answer to the MAINCAP question. NO, you cannot use the maincaps from another motor without some nice machine work

 

yeah a good align hone should solve that main caps problem ....pretty sure someone will correct me if Im wrong

 

If you use a cap from another motor, you'll have to have it align bored and then align honed . They are machined on the block at the factory for that particular block, so you have to re-bore the mains before you align hone it.

 

ok i got the pics now so maybe yall can tell me if it can work or not.

 

those *look* like they could be bored out.. maybe u need to go to a different machine shop

 

on the first and third pic you can see the scratches on both sides pretty deep.

on the last pic you can see the crack between the sleeves. thats how all of them are. is that normal or what?

 

also the guy i bought the block from told me they were benson light sleeves. has anyone ever herd of that? ive herd of benson sleeves but not light.

 

Those don't look like bensons sleeves. Unless they welded a block gaurd in there too.


::confused::

 

sorry dont look no benson sleeves to me

 

Looks like a junky sleeve job to me.

The cracks between the cylinders are very likely to cause a leak. We just had to repair and re-sleeve a block that came to us with a crack between the cylinders like that. Whoever installed the sleeves didn't do it right and cracked it. It looks like they welded in a guard and use thin wall repair sleeves. Boring it to 84 with a thin wall sleeve is pushing it.

Those are Bensons,

...Daryl Benson that is. He installs these sleeves for $50 and a fifth of "Wild Turkey"

 

Is that a deck plate?

 

damn so basilly that motor is worthless?can it be repaired without costing so much? the guy said theyre at 81mm so maybe i can bore them out to 81.50?

 

Take it to a good machine shop and have them measure the depth of the scratches. If they are less than .25mm deep, then you can probably get it bored .5mm over. I have a bore micrometer that I use to measure that, but it costs a few hundred dollars for a good one. Definitely get a second opinion from another machine shop, as I've used some machine shops that were really sharp and some that were nightmares. I'm running Darton sleeves at 84.5mm now, I had to go .5mm over my original 84mm bore after I melted my pistons and scratched up my sleeves.

If you don't have all of the original main caps, then you are kind of screwed. You will need to get it align bored/honed, which is a tricky operation on a B-series. I had a machine shop lose my main caps and give me my block back with some different ones, and it took some serious work to get it all straightened out again. RLZ hooked me up and the engine is running strong today, but they are one of just a couple of shops that I'd send that kind of work to. If you do send it to a machine shop, then be sure to mark every part that you send.

 

FYI, these are benson sleeves...



it even looks to me like you have stock sleeves with a broken block guard..?

 

Can you take a picture of the block from the side?

 

are you sure it has been sleeved? look on the underside of the block and see if there is an actual sleeve installed in the block. Darton made some sleeves that look like stock sleeves. They are pretty strong.

 

I was also gonna say they look very similar to my stock sleeves on my b18b.

 

i just got my sleeved block back and they look similar to your sleeves. they hog out your stock sleeves as far as they can go then slide in new sleeves then add a block guard the guy who did mine has ran up to 36lbs with no prolem with these sleeves. i'd say sell me that block ill bore it out to 86mm and make it my NA block but im sure 84 mm will work just fine

 

do you guys not see the difference in craftsmanship between my block posted above and 90 integra's block?? clearly does not look benson style, and it really doesn't even look like anything other then stock sleeves with a swiss cheese block guard...

yeah dude, I also say sell it to mattcivic and get a clean benson block

it may work for NA but I wouldn't trust it with boost...

 

thanx for all yall inputs and suggestions. i was planning on building a ls/vtec for another car i have but my whp goals are to reach the 260-275whp. but i guess im start all over again.
