Power steering box leak
 

My 67 GTO steering box is leaking at the adjusting screw at the top, Is there a easy fix? If so, could somebody give me some advice. Thank You.

I don't recall any seals at the top adjustment nut so not sure there is an "easy" fix.
I have seen/read some online post about using O rings and/or Teflon tape?
Some have mentioned success with just re-tightening the nut.
(Being VERY careful not to change the location of the screw)
or at the least be sure to record the number of turns in or out if you do so.

I tightened mine about a 1/4 turn and it quit leaking.

Nut was very tight, Was thinking of taking of the nut and putting some ultra black on the threads. The fluid seems to be going up the threads to the top then dropping off. Thanks for the help.
