the old 580B Question

I have a question on the 580b case, The enine is a 188 and has the im thinking power shuttle, well the starter has a little bolt on the housing between the starter sylinoid, and starter motor, this bolt keeps leaking fluid around it, is this an adjustment bolt? can it be removed and an o-ring put on it to keep it from leaking? I guess a pic would help also ill try to get one


Thanks Mike
