Regardless of the reason, if you are using the updated PTFE seal,
never use any type of sealants. One of the quickest ways to get one of these to leak is to use sealants.
Crank sleeves are used when a seal has worn a grove into the crank itself, making it impossible for the seal to work. They are at best a stop gap measure, and will not address your problem.
