I have a boosted 98 usdm b18c5 that i thought i blew a head gasket on but today I pulled off the head and found that i destroyed my cylinder wall on one of my cylinders and slightly damaged my piston and head with the fragments from the wall.
My question is if it is possible to resleeve this same block even with the current sleeve being completely destroyed as in cracked about half way down. I thought that sleeving was not possible once the wall was cracked but i read another thread where someone said something about resleeving a cracked block sleeve.

Also is there anything i can do about the chips on the head and piston? I know im screwed but im just trying to find out just how screwed i am....
here are some pictures to show what i mean...

yes it can be sleeved with aftermarket sleeves

 

thank you, anyone else have anything?

 

it can be sleeved, but depending on how bad the crack is, some shops may not take that job on.

 

just replace the pistons, and a fab shop can fix the head.

 

i sent a block that looked like that to Golden Eagle probably 4-5 years ago, and they would not sleeve it, so i had to send them another one.


why does the finish on the head surface look so "crude" ???

 

i had the same issue, i blew mine up and i plan on sending it to GE for a re-sleeve
perhaps ill send GE a few pics first to make sure they can do it maybe thats what you should do

 

thanks for the responses, i really hope it can be fixed...as for the pistons could i reuse the same one or is it possible to purchase a single piston cuz they have <4k on them as well as the rods....if i went up to around a 84mm bore with some new pistons could i still use the same rods? (i currently have 81.5mm pistons)

 

you can buy singles

 

If you resleeve it, you could get 1 more piston (and 4 ring sets) and have them hone each cylinder to match the corresponding piston. You could go with 81mm or bigger w/new pistons, but that would cost $200-300 more for basicly nothing. New rings would be needed for all four to break in evenly, as well as its a bad idea to use even slightly used rings on a new bore.

As for the head, you could have someone work all four chambers so that they are the same volume. The only problem would be any warpage, cracks, or iron chunks stuck far into the head. A small magnet, x-raying, and resurfacing is what the head needs to be reusable (for high-hp F.I.).

 

thanks alot for the good info, it really helps. i guess now i just need to hope it can be resleeved....how much am i looking at for resleeving as well as for the head work? I was told it would be around a grand to get the block sleeved with shipping charges included and im clueless on what that kind of head work would cost...

 

That block can be sleeved with Darton MID sleeves as long as the bottom most 1.5" of cylinder wall is intact. I have fixed worse than that. Bore size range 81 - 84.5 mm or anything in between.

 

anyone have any info on possible prices?

 

damage looks almost identical to my motor when it cracked a sleeve.

send it out to golden eagle. i paid a little more for mine since i had the rush put on it though. $800ish for normal service and add $200 for the rush

 

Steve_D said it correct. You can sleeve it if you have enoug at the bottom.

As far as I can remember, for Darton MID on a B18C5 the crack can be up to 114mm from the deck.

Check out theire site to see it exactly.

i was told a cracked sleeve couldnt be resleeved...

I wouldnt.. but thats just me.. and some places wont even touch it

 

Steve D is correct. You can resleeve the block with our MID kit as long as the damage does not go all the way to the mains. TheMID sleeve does not use the stock casting for support so the outer wall would be removed anyway.

 

This is a good thread. So would GE be willing to take THIS on?

like Steve D and Darton said, up to a certain point it is still Resleevable, at least with the DARTON MID. From what I've seen on other sleeving process, they cant sleeve it if its cracked after 2 inches from the top. the Darton MID is a good choice if you want to save this block.
What we can see is only the top part so you really cant tell until the pistons are out, and the block is in the hands of the machinist.
Darton MID sleeving is about $1300 for the sleeve kit, the labor for the machining, and that is including the final bore, hone and deck of the block.

 

thanks everyone for all the info ill have to see how bad it is when i finish taking it all apart

 

Crack sleeves can be resleeved with aftermarket sleeves. I've sent 2 blocks in to GE for sleeving and both have hairline cracks going down about 2 inches.

however, I was told that if the sleeve is cracked beyon a certain point, it cant be resleeved.

</TD></TR></TABLE>yes we would 99% of the time we can fix them but i would need to see pics with the pistons out to see how far it goes not on the og sleeve but the aluminum behind the og sleeve because that is what will tell you if it can be fixed or not

 

The block definately looks resleeveable. We have sleeved many blocks far worse than that with the Darton MID sleeves with no problems. Pm me for pricing if interested.

 

how much was u boosting?
