tricks I've used.
add some power steering stop leak to the fork fluid. I also pulled down the fork leg cap and wrapped the tube up against the seal with a piece of felt saturated with the stop leak and then reinstalled cap.
also I loosened the fork clamp one side at a time just enough to allow rotating the upper fork tube 180 degrees, re-tighten fork clamps to spec. both sides if both are leaking.
my forks haven't leaked since.
So I did the felt thing with the 180 degree tube rotation but I couldn't get the fork tube cap off. It turned about 10 turns then just kept clicking and wouldn't unscrew any more. What did I do wrong?
Is the lock nut holding it somehow? Am I a Dingus or what?
