Pinning a Sleeve

[Henry's Lady's Man]

The machine shop found that one of my cylinders is sleeved, and my water leak may be coming from it. He will let me know what he finds tomorrow when he removes the sleeve. Also, some ass bored out the stop at the bottom of the cylinder. Though my sleeve didn't slip, a new one could.
Question: What are the pros and cons of pinning a new sleeve so that it doesn't move?

common practice
it may already be pinned. once pinned and bored/honed you can't see it

You could also possibly have L.A. Sleeve make you a stepped sleeve with the step at
the top. You have to counter bore the block at the top for it and let the head gasket help
hold it down. Just another option.

I do it all the time when I find sleeves that are bored all the way through.

Ok. I didn't realize how common it was to pin it. Thanx for the responses. Chuck

I rarely pin or step a sleeve.

KR Wilson combination machine bores the block all the way through for sleeves. Have built over 70 engines with the combination machine and not had a sleeve slip.

Here is another idea, get a sleeve that is just a little oversize by a couple of thousands, then freeze the sleeve or put in dry ice, insert the sleeve in the block. When the sleeve comes up to ambient temperature, it will be an interference fit and will not move. Have use this technique for installing bearings.

They do make repair sleeves (liners) with different outside diameters. You will have to have the engine builder find a sleeve with a suitable I.D. and O.D. to fit your needs. I've installed a lot of liners this way.

Now I LIKE that idea. Don't know that the machine shop wants to mess with dry ice tho.

if you use the dry ice method you'd better be quick
it will warm quickly because it is thin and can't hold the cold
if you get it half way in and it becomes too warm it won't move and you are screwed

In lieu of dry ice, I have used my argon bottle for TIG welding and turned it on its side to produce liquid nitrogen for chilling a race prior to installation. Just use care and a thick pair of gloves.

(BTW, I sent you a PM a few days ago.)
