If you use liquid nitrogen, the sleeves will shrink about 0.005" and will literally drop right in. A compressed gas place will be able to sell you LN2 (symbol for liquid nitrogen). A big coleman cooler to hold the liners, filled with LN2 will do ya. But (important) don't ever ever seal a container of liquid gas it will expand and pop. You will probably have to put the cooler in the back of a pickup - N2 could smother you to death in a closed car. But you are in Texas and everybody has a pickup, right? /forums/images/graemlins/grin.gif

Oh yeah, you will need big thick gloves and some pliers too as the sleeve will be so cold it will literally freeze your skin to it.

Great work get'n 'er done!

LN2 is available almost everywhere on earth.

I used to work at a company which shipped many products in LN2. We could get the containers refilled almost everywhere. The original reason for this was the beef industry. Bull semen is shipped in LN2.

Eddie: If you try LN2 do only one liner and get it completely in before you do the second. I knew a guy 30 years ago who had access to LN2 and thought it would be great to shrink the valve guides on a Jaguar engine he was rebuilding. Well, they didn't shrink--they permanently expanded. Some kind of funny alloy. He had to buy new ones.

I don't think this is very common, but it has happened.

the sleeve will be so cold it will literally freeze your skin to it.

This can be an issue with dry ice also. If your skin does freeze to it, don't rip the skin away -- pour warm water on it. If you don't have any warm water handy, the official US Navy method of getting the skin unfrozen is to pee on it.

You do not cool or freeze WET sleeves when installing in the block. All this talking of chilling them is for DRY sleeves only as they can be as much as .005" interferance fit.
When installing a wet sleeve you clean out the step at the top of your block and the sealing surface near the bottom, lube your seals with liquid soap and set that puppy in the hole. It will freely go till the sealing rings (o-rings) contact the bottom of the water jacket. Check your sleeve for proper index with the crank (notches in bottom of sleeve). At this point lay a peice of clean hard wood across the top of the sleeve and while holding the wood tap the sleeve home. Do not hit it hard, just gentle raps with a 2LBS hammer.
You could also make a fixture that will bolt to the top of the block going across the sleeve and push it down with a small hyd jack.

Guys, these are all good ideas, but isnt a freezer a common appliance? I mean a deep freezer used for keeping meat.. Most everyone I know here has one, plenty big enough to hold 6 sleeves... Just curious, the other ideas will work but I'm thinking simplicity.. Also, a space heater under the engine with plywood leaned up againt the dozer should help get the block hot.. The sleeves should just about drop in..

I would check into what whitetiger just said. I just finished a rebuild on my engine and it had dry sleeves. I believe he is correct in his statement that freezing is for the press fit dry sleeves. Wet sleeves should drop in and be sealed by some type of O ring. Mine not only had dry sleeves they were the thin can liners and had to be cut out. Then the shop froze the thin liners, heated the block and dropped the new liners in.
