Yeah, per a previous message one of the couplers off the roll over valve was destroyed, so I have replaced both. From the inlet of the evap solenoid (at the radiator) to the tank holds pressure fine, if I cap that line to the shut off valve. With the car running and the shut off valve energized, the whole system holds pressure. By holds pressure I mean it holds pressure for a while, not indefinitely. I can only assume that's how it's supposed to work, so either the smog evap test needs to give this car a pass, or they need to test it with the engine running. Either way works... I know the smog tester guys pretty well (I own a lot of cars) so maybe I will swing by and see if they can tell me anything about how it goes. I've never paid attention, because in all the bazillion cars I've owned none of them have ever had such a ridiculously complex evap system. :shrug:
