0.014" is way too thick in my opinion.

Unless you let the sealant set up too long you might want to make sure the bore for the nose bearing is not boogered up and keeping the case from properly closing up.

You should also check all the mating services for any dings and mars that may be causing this.

Its a good thing you had to take it apart since thats enough slack to keep the bearing shells from properly crushing/clamping.
