Thanks for the reply. That is how it has been installed, Left example, and has always had a seepage issue. The outside of the Master Cylinder bowl always has a wet appearance. A closer look at the gasket reveals a set of seating/sealing rings on the up side away from the MC bowl edge. It seems, to me, these rings would have more effect seating on the bowl edge rather than facing away from that edge. That would be the RIGHT side example. Thoughts ? Thanks, Brian
