SLEEVE LOCKS
When boring and honing engines with sleeves that have only a light press fit, we have found that the torque from the honing operation may cause the sleeve to slip in the engine case.  We use 4 old 4-sided carbide inserts and some clamp bolts and nuts from the milling machine to hold the sleeves in place.  The inserts clamp against the sleeve flange and engine case.
