i am curious too.

For those with this mod and go for smog test (such as California, Illinois etc.),
any issues with smog test?

My guess is that: it is probably OK.

I'm going to be getting one this weekend. If they fail me because of it, I'll be going back to the stock system. The CCV is still there. I would just need to replace a couple hoses. I'll let you know.

For those who went for emission testing, do you re-install the cosmetic cover
to hide the "Art Work"?

PS: I have never this (CCV Mod) being an issue during smog test.
All the smog stations care is emission pollutants, if the tailpipe output is clean,
then you are OK.

I put the cover on. I also used the factory elbow coming off the valve cover to try and keep it looking as stock as possible. Only thing that gives it away, besides the catch can hanging in the engine compartment are the non-factory hose clamps that are visible. I could have replaced those with factory style, but I was lazy.

Sometimes I wonder the intelligence of these smog inspectors...

Let's say a driver modifies his/her car such as this.
Of course it is not factory (it is better than factory IMHO).

So what, as long as the tailpipe emission tests are good.
I understand why they look into the engine compartment: the purpose of this should be to look for broken hoses that can potentially contaminate the environment.
If the hoses are fine and all they see is a mod, so what...

If they ONLY focus on the tail pipe, then what we did as a mod should not matter...

In New York, they don't open the hood, just plug the computer into the OBD port.

This state requires them to look under the hood. I think if left to their own devices the smog guys would just hang the sniffer in the tail pipe and run the test. Less work for them.

Also,

That is better too bc the bottom line is how much pollutants come out of the exhaust.
And they only way to test that is to hang the sniffer in the tail pipe.

Had my smog test yesterday. Passed. No issues.

Did they (California) open the hood to look at your "art work"?
