Howdy,...

When I get into a bind and can't get the correct parts (Packings), you will have to improvise like I do.

I usually take a sleeve to a Hydraulic Shop and match up O Ring's that will fit into the groove and take up most of the space but isn't much larger than the OD of the sleeve when installed.

If they are too large they will get cut uneven when trying to install them in the block and most likely leak. Usually the O Rings are thinner than the groove as most packings are half moon shaped and not round.

Then I use Permatex Ultra Blue sealer on the sleeve groove, then install the O Rings, then more silicon on the top of the O Rings.

I also use a ball hone in the lower end of the block and put a thin coat on the block bore then install the sleeve and hold it in with a clamp or weight a few days.

Only silicon the lower section where the packings contact as the head gasket seals the top end.

The Ultra Blue Silicon works well. I have had to do this on over 100 sleeves to date and no leaks. Some have been in use over 10 years with no problems.

The Ultra Blue Silicon expands and contracts better than just the straight Blue Silicon, and bonds better to the parts.

I know this is not what they reconmmended when these wet sleeves were made, but they didn't have Silicon Glues and Seals back then anyway.

The only drawback in doing it this way is it must be very clean, and to remove the sleeve at a later date, you will need a Sleeve Puller and can not tap them out like some folks do.
