I tried stacking washer( no good) I had to try several washers before getting combo that worked. The new NAPA master Cylinder does not have the spirals on the mating surface as OEM had so through trial and error and numerous attempts, I finally got it to stop leaking. I tried 10 different crush washer all the same size. 57 chev 3800
