Sleeves

A good machine shop will install sleeves in blocks of all types. I know of no engines that could not have dry sleeves put in. The primary use (and quite often done) is to repair an engine whos block is very rare, or more expensive to replace than sleeve.
In some cases it is possible to sleeve an engine just to be able to use a good set of pistons. Shrink fit sleeves can be installed without a shoulder on top. Either by careful shrink fitting of a straight sleeve, or the bottoming of the sleeve on a ledge made during preparation boring for the sleeve. Either way the new sleeve is machined off flat at the deck (top of block) and seals against the head gasket. The only issue I know of is the marginal success found when trying to sleeve a cracked cylinder wall. The uneven pressure, cooling, and corrosion at the old crack cause problems. Machining the cylinder to waterjacket, and installing a "wet sleeve in an engine with cast in place cylinder walls is not done because the block depends on the compression strength of cylinder casting to resist internal forces and stress, including head bolt pressure.
Works for my customers in the past, and on things from aluminum briggs blocks, to rare or one off jewels that would be junk without a sleeve. Ive never seen a sleeve fail (except in a cracked block. Good sleeve repair makes old better than new sometimes, metal used by reputable sleeve manufacturers, often wears longer than cast iron. Lots-0-life, Jim Nicholson
