Trying to find a substantial air leak. From 130 psi to 30 psi in an hour. Already pressured the system externally and gone over everything with soap. Found a few little ones but even with those fixed the pressure is the same. Can't hear anything. Ideas as to what could leak that much but not bubble or hiss? Extra info: if it matters I get a strong whiff of gear oil each time I set the park brakes and the park brakes set quickly but hiss for 20 seconds or so and I can hear air flowing but not leaking under the dashboard when they do. On my phone sorry if awkward. Ken.
