California Smog Test Experiences
I've had quite a few questions about the CA smog check following the PITA I went through to have my 01 smogged and decided to start this thread.
Please post about your Ca smog experience - did you pass/not pass. Reasons you did not pass or what issues you had. If you passed fine - what did you notice they checked or did the tech give you any info that may be useful to others.
Do NOT post the shop where you did your smog check, only the city you are from. Some members may want to PM you based on your experiences and we would not want to publicize any info either way on smog shop locations.
Also, I have read countless claims about exhaust/intakes not being able to affect the smog shops decision, however NOBODY has ever been able to produce official documentation from CARB or DMV stating so...if you come across legitimate info, not simply what you believe, please post it here and the source you obtained it from.
I had my 2001 psd smogged in Modesto, CA. I had a 6637 filter on which they did not question at all. They failed me for having a tapped and plugged hole just after my 6637 in the 45 degree elbow. They said despite the fact that there was nothing that would contribute to its emissions, it is considered a "modified intake". What gets me is the 6637 was a legitimate modified intake, the plugged hole in the elbow was just to fill a hole but after I borrowed a buddys elbow, they passed it no problem. I also had a fully welded aftermarket 4" turbo back exhaust with no cat. The truck was originally from Oklahoma and did not require a cat.
Hope people from CA can contribute and shed some light on what smog shops are doing around the state.
