In this image from LMC Catalog (Page 152); what keeps the grease inside the cylindrical part on the engine ball stud? Should there be a seal before and after the ball (like #10 on the opposite side).
Also the ball stud on my block is no where near the same diameter of the cylindrical part (it's smaller) so I would guess it wear over time (maybe why there was nothing there when I took it apart).
Thanks for any comments.
