My car has been parked for 20 years outside. I've built a new shop so I can finally work on it. After new brake lines, MC, wheel cylinders rebuilt, Dot 5, the clutch slipped from being oil soaked. I installed the Andy Bernbaum seal kit in the fluid drive. When I pressure check it (15 psi) there is a small leak at the carbon seal. Is this normal? I took it apart and tried both sides of the carbon seal and the back side of the old carbon seal and ended up with the shiny side of the new carbon seal against the seal surface. I know water pump carbon seals "break in", so I'm going to see if this one will break in too. 🤞
