True. Not "open vented", but it will not pass EPA lab testing in brand new, original stock configuration.
Cheers,

Working properly the Vanagon tank is not quite open vented. It should hold air pressure and the vent valve should only open with the engine running and throttle opened.

Odd that the smog guy did the EVAP test. All the guys around here put it down as "not testable" due to the location of the hoses.
Most smog guys are clueless about how the Vanagon EVAP system works.
Funny (or not) thing is, a brand new, stone stock Vanagon would never pass the CARB laboratory EVAP test as the system is "open vented." Lucky for manufacturers that they never had to have any CARB tests done on their vehicles because manufacturers are considered self-reporting entities. All they have to do is state that their vehicle meets EPA and DOT standards, and they're good to go...
Cheers,
Jeff

I could go on and on about CARB and why they are the bane of my existence..
But I also like my air quality..
Anyway, took the Vanagon to the SMOG shop. They were nice enough to pretest without charging me.
Failed on the EVAP test, this is where they pressurize the fuel system and test for leaks. Any common places where I should look first before going from nose to stern looking for it?
Also failed on the emissions. Previous owner stated that they replaced the catalytic converter. I've done all of the vacuum hoses that I could find.
Complete ignition tune up and timing. I've also got an air-flow meter ordered as the one on the bus has been "compromised" (opened up).
Anything else I should play with?
