hey, i've just finshed the repair procedure for this one. This one is much more complicated than replacing the two little screws, but if they're missing, go to Acura and order them anyway. While you're there, order eight, (8) of part # 91608-SJ6-003. It's a white rubber screw...cap thing. What's causing the leak is this part...after about 10 years or so, they become yellow and dry rot over time, thus letting in water, one drop at a time. I got the repair procedure off of G2IC, so here's the link for it.

Hope that solves your leak.
