It keeps on leaking oil, a little bit, but its there.

The 2 oil ring sits at the right spot.

I did some googling and some people having the same problem,

and they *sand* the filter area with sandpaper to fix the problem(notice: not sanding the sandwich itself)

What you guys think ?

I was looking at Greddy's site b4, they have a oil filter sandwich just for FD3S. I wonder if I should've got that one instead ...

 

Thread revival. You fix it by sanding it or what?
I can't get my prosport to seal!
