I haven’t had any problem with mine passing, so far, I’m in N. Va & don’t know this for sure but would guess my county has to be “top ten” in finding a reason to fail you.@bereta1 I bought and installed a Moroso which is probably far more expensive than any catch can needs to be. It's all pretty straightforward, and plenty of folks have installed less expensive units and are quite satisfied.
Note: The area where I live still does yearly inspections for Safety and for Emmisions. Making this minor modification would probably cause me to fail one or the other, or both? I'm not sure, so I saved everything I took off and return it to stock every year for 1 day to pass inspections. I keep it in the box the catch can came in.
I'm going to talk with the owner/head mechanic this year, see whether or not they
will fail for a catch can. It's a very quick and easy swap though.
Keep the original hose and don't mod it for a catch can, then it's easy to revert back.If the catch can's not hooked up,would it pass,or does it have to be completely removed to pass? I've never had to deal with smog emissions,so curious if leaving it in place,but not hooked up would still fail a vehicle.You guys that live in the United States are lucky. I'm stuck just west of the US, in California. Catch cans will make you fail the smog check when they do a visual. I might try Curmudgeon's method of reverting to stock for smog check days.
May depend upon state and particular inspector. In California they r friggin ridiculous with their CARB rules. Another reason IMHO to never reside there.Keep the original hose and don't mod it for a catch can, then it's easy to revert back.If the catch can's not hooked up,would it pass,or does it have to be completely removed to pass?

DANG PA, NJ that whole area on inspection stuff. Heck, as a kid in the early 70's NJ, having to go to state inspection stations where they did emissions, jacked up car checked ball joints, etc, headlights. SEEMS like everytime failed for headlights and of course there was the "private" garage right next store that did headlight re-alignment and you got yer sticker, tell me that wasn't a gimmick. Of course, after you paid the entire re-inspection fee and the garage fee for the "proper alignment", etc .,.In my case I just removed the hoses from the PCV and throttle body, loosened the bracket for the catch can and slid it up out of the bracket hoses and all, leaving the bracket still attached. No law against an empty bracket!
After inspection it is easy to re-install. I take advantage of the time by emptying and cleaning out the can.
My only experience with emission testing was back in the 80's when I lived in Phoenix and Tucson. I drove a 74 Chevelle S3 Laguna, and it almost always failed emissions on the first try. At that time, in that state, if you failed you could retest up to two more times for free. I would have been more pro-active with tuning my car before the first test if I had to pay for each time they checked it.DANG PA, NJ that whole area on inspection stuff.

I still think the S3's were one of the best looking Colonade bodies GM built in the mid 70'sMy only experience with emission testing was back in the 80's when I lived in Phoenix and Tucson.

Thankfully they don't do emission testing in my county where I live now. Although now I drive vehicles in much better condition than I did back then lol. And would have a much higher chance of passing the first try.
Yeah, I loved how that car looked. It was the early 80's when I had that car, so of course I had rear air shocks, large 50 series Micky Thompson's on the back and smaller 70 series Polyglass GT's on the front. All on slotted ET mags. And the swivel bucket seats were great. Made it real easy to put my son in his car seat even though it was a 2-door. Sit, swivel, place child in seat lol. Yeah, those were the days!I still think the S3's were one of the best looking Colonade bodies GM built in the mid 70's

Check out Ed's thread ,i'm pretty sure he's got pics of his intake ports posted,you'll see why a catch can is a benefit on a hemi.I guess I'm in the minority and don't see the need? I haven't had one for the past 9 years and everything seems fine? What am I missing, and if they are so important why didn't the engineers think of adding one?
Now just imagine what the inside of the intake manifold looks likeI guess I'm in the minority and don't see the need? I haven't had one for the past 9 years and everything seems fine? What am I missing, and if they are so important why didn't the engineers think of adding one?
