Repeat M/C leak from reservoir lid

[RedRoad]

Larry Id like to know too, I dont see that 72 in your sig so I hope you didnt sell it because of the leak!!

My K20 has done the same thing for the last 2 years. All new brakes, hard and soft lines, cylinders, booster, top/gasket, NOS top, thicker gasket, replaced the OReily master for a new ACDelco, replaced the front calipers AGAIN, bled, bled, power bled, gravity bled with the same issue.

I got another used prop valve and will try it out but hopes not high.
