The LS9 block listed on corvette forum from a well known member has been machined and ready to go just fyi

Sdmodified

Thanks for letting me know, but I don't really need to spend that much on an LS9 block, since my build would not trully benefit from the LS9 advantages.

Edit: Looks like it sold a few days ago anyway.

I’ll ask my guy. I know they have done singles in LS6 blocks.

I stumbled on an L99 with two bent gods for $500. Block and crank were fine. So they are out there.

Crap! Ha! Got me.

anyway, to the OP, my machinist says they can and have put one sleeve in an LS3. I can get more details if you like.

Thanks! I actually found a machine shop here in New Jersey that is going to do the work.

There is so much misinformation out there on the internets.
I was able to get in touch with Steve at RED who is an awesome guy and extremely helpful. He gave me details on how a darton replacement sleeve is installed and said that one sleeve "CAN" be done on the 6.2 aluminum block, (most of the time)... He was willing to do the repair but I quickly realized that shipping from New Jersey to California and back is very expensive and would actually cost more than the repair itself. However I do want to thank him for his help. If I ever do a full sleeved block, I wouldn't consider going to anyone else!

Currently, I am aware of two sleeve options that I will discuss with machinist:
Darton part number - RS4.0625 1-8
Melling part number - CSL359F

I will update this thread as I move forward in the process with the shop. Fingers crossed that this works!!!

what pistons are you going with? I'm in the same boat similar crack in cylinder 4...Im considering just buying a new 6.0 block and having it bored out to 4.065" and just reusing the rotating assembly from the LS3 vs cost of re-sleeving the one cylinder, going to 4.070" and buying 8 new pistons and then having rotating assembly rebalanced as well

As of right now, the block is at shop along with all 8 pistons. They are hoping to not distort the other cylinders, so stock pistons hopefully can still be used. With new rings of course. I will update when I hear from them.

Say a prayer, from what I have seen w/ sleeves the distortion on the neighboring cylinder is guaranteed. At least take it to a pro shop after work to have them check it vs slapping it together.

Sdmodified

From what I have learned, it depends on the block and type of sleeve used. LS1 blocks are different than ls3 blocks, etc.

For the ls3, the melling and darton are installed differently. With the melling, cylinder is bored to 2 thousandths and the sleeve is press fit in. With the darton sleeve, the cylinder is bored 1 thousandth over, the sleeve goes in loose, loctited in place. The shop I went to will be using the darton. Since they are not pressing in the darton, it seems there is less possibility of distortion to other cylinders. They also say the darton is much stronger. Of course I am no expert and nothing is guaranteed as every block is different. So we will see how this goes....

Trust me, you will have to hone the block after sleeve is fitted. Or if you don’t believe me, call Steve at RED. He’s the absolute best in the business at sleeves. Been doing it 40-50 years, and holds patents on a lot of this stuff. Do not let the shop try to convince you that it’s ok to fit the new sleeve and all is well. I’ve done this before, as I said in first post. Adjacent cylinders will be distorted. Just trying to help you here, that’s all.

Sdmodified

The hope is only a light hone is needed to clean them up if they go slightly out of round. That way stock pistons can still be used. We shall see soon enough. I am doing my best to document this experience and will post up details as this process unfolds.

any updates on how this turned out?

Sdmodified

have the block at the shop. They are sleeving it this week. Will post pictures once it is complete and give full details. Right now they are planning to use a single darton sleeve and just light hone all cylinders and deck the block. Fingers still crossed... Haha

So were they able to sleeve it and keep the 4.065" Bore?

Racesloth

Yes was looking for an update - curious how this goes and performs when put back together...

****, if you're going to sleeve it, spend $0 extra and go big bore. (well, maybe a $600 set of pistons)

I 100% agree if he was doing all 8, but he's doing a single sleeve, with the other 7 being stock the biggest he can go is prob 4.075", OP said his goal was to use 4.065" pistons after the repair
