Yes the sleeve/holder can be damaged.....rather the perk tube (boiler section) can be damaged if weld used to secure sleeve to perk tube was improperly done by a hack at factory.
Over-penetration , excessive heat/amps combined with the thin walled tubing mfgs. went to to save material costs
So wiggle and TAP on element NOT sleeve/holder
