Alan :
If it is seized that tight (i.e. pressurizing the bore with 90 psi shop air
won't push it apart), then chances are excellent that the bore is ruined.
Sleeving or a new MC would be the only fix.
Re : brass sleeving, any machine shop (not the automotive variety, but the
people who make tools, etc.) should be able to do the work. Probably more
expensive than a shop that specializes, tho.
