I bought once 50 valve stem seals from Elwis Royal. Only 20 of them were usable, the rest went to trash can... I never use that stuff. Victor Reinz and Corteco are preferred. My own engine was assembled with Ajusa kit. 30k km with hard loads, no any issues. For NA engines I use sometimes Glaser, Pay...

No special tool needed, just a hint:

The only way is to assembly internal parts of D5244's alternator with the B5254's alternator housing. Isn't it easier to buy properly spares (brushes, contact rings, bearings etc) and fix your alt...

Removing fan is pretty easy, and you will have much more space for work.
