KuHL 951

Thanks. That's good to know because I got my info a few years ago from a 'test only' facility when I was having smog issues, none of my 86 951's or the 87 944S were ever subjected to this additional test; only my 83 with the exposed canister in the wheel well. I guess most techs must now know which evap lines to crimp in the engine compartment? Since you do this for a living: Do you know the pressure the machine applies to the tank for the test and how long it has to hold a given leak down value? Also, does the initial evap test 'fail' show up on re-test paperwork at another facility? This state stinks for car enthusiasts.

applies just over 1 psi, and the smallest leak... in the thousanths, will fail. usually our lines are brittle, so in the past, when a tech see's them like that, they wont crimp them to risk damaging the lines and skip the evap test. But now with STAR stations, it is a must. To ad, yes, the initial evap pass or fail results are saved and show up in the vehicle's history.

How long has this been a requirement? This is the first smog I've seen someone do that test since 2006, and the car has been run on a sniff machine 5 times since then.

since 2009

That explains it I guess. My last smog was at a 'test only' when I sold the black 951 in 8/2009 even though they didn't check the evap loop that time either. Looks like Spencer will be dropping the TA and tank afterall...oh joy of joys! Thanks for the update because I'm actually considering buying another 951, I believe the major scars have healed enough to try again but I'll register it in Oregon this time where no smog is needed

I got smog in Feb'12 and had to go to the same guy twice since my cat was bad the first time, and he didn't do it either time...

all on the tech like i said, but if your test is required at a STAR station, an evap test will be performed 100%
