Default L33 block with lifter bore damage... worth it?

All,

I am in search of an L33 block and one just popped up on eBay for a great price but with lifter bore damage on a single cylinder.

I will be shipping the block out for dry-sleeving.

Is this something that can be fixed with a hone or is this something to stay away from?

Thanks,
D

was talking to my engine builder the other day. He does warranty work for GM and mentioned they sleeve them.

Yeah - after looking at those pictures in more detail of the damage I am concerned that it would require a machine shop's attention. I would rather be patient and just get a block locally for $300 that is in decent shape that spend $300 on one shipped with damage.

If anyone thinks that the repair on this block would be under $50 then by all means chime in!

I would not buy that block. Like cobalt said you can get one in good shape, maybe even an entire long block for a good price.

It's hard to tell the extent of the damage from the pictures. If the damage was just at the bottom of the bore, I would probably just deburr and run a wheel cylinder hone through it. But I would not take the gamble of buying it without seeing it in person.

Thanks - but I can get a whole short block in good shape for $300-350 plus shipping from that same seller online.

Looking to spend about $250 for just the block if I have to pay shipping.

Feel free to PM me if you can't get rid of it or are willing to wiggle on that number.

Thanks for all the input guys, I agree it's not worth the gamble could easily be a $250 paperweight after it's shipped to me.

if you can get a short block for 3-350 I would not mess with a hurt block for 150 at all.

post script; gen 3 l33's are getting very popular, and the prices have been going up on them lately. if you want one and know where to find one you need to buy it. they will be gone soon.

I'd pass on that block. To properly sleeve that block, you need someone with the right equipment. That usually involves a fixture specific to your engine (LS1) that goes into the block where the cam sits. This fixture is then used to bore out the lifter bore and install the sleeve. That's way more than a $50 job!

It also looks like the bottom of the bore is deformed, like the lifter was beaten out of the bore. I'd stay away from it. It's not worth a $150 gamble, especially if you can't see it first in person.

I just went through this with an LS2 block!

The gen 4 blocks they have are a good deal. They are the strongest for sleeving.

There is regularly a short block on eBay for $300-350. I have not noticed any increase in prices but I have only been looking for a few months.

If I can't find one I will contact you.

Much appreciate the input.

Good point about the lifter being banged out the bottom.

I was hoping for some first hand experience!

I will keep looking out for a block. I am not in a rush to find one just wanting to get a great deal. I won't be ready for assembly until the end of the year anyway.

Thanks!

Check craigslist for a good local deal on a bare block or a shortblock. That way you can inspect it first-hand.

Lift bores with light scratches or small light scuffs are usually okay. Worst case, your machine shop can lightly hone them by hand just to get a good texture on the bore.

Gotcha - given that I am going to have the block sleeved I am mainly concerned with the deck surface, lifter bores, and mains. Being able to inspect the block with a set of mics would be a great added benefit.

Thanks again for the input.
