I know this has been asked a gazillion times, but to clarify, has ANYONE had any problems passing the VISUAL part of the inspections on JUST BPU? I.E.- FMIC piping, intake??

No. BPU will not pass the visual inspection. You will fail on the intake and then on the no catalysts.

I failed and I was barely the B in BPU.

your car has to be pretty much bone stock to pass visual for the most part. i remember going through that crap. not fun:sad:

They go as far as checking all the vacuum lines from the diagrams in their books.

yeah. i dont know if normal smog stations are as picky, but when i was at the state ref i was failed because a vacuum line was off my BVSV... i actually got better test results with some vacuum lines off than when i came back with them fixed...

But for some of us people who arent "who you know" oriented it makes it a little harder for us to get our cars to pass. Oh well, its the price we pay to own these cars...

I pass visual while BPU w/ carbed intake, Apex FMIC, and catted DP.

i really think it's up to the smog station cause a fmic and an intake don't have an effect on smog!!! cause some other new car have a fmic now installed as an oem.

BOV doesnt affect smog either, but you'll get popped for that too...

One test-only station failed me for metal intake pipes :rolleyes: & mine are powder-coated black - no polish/bling under the hood. Luckily they weren't lame enough to charge me anything for that.
Drove down the street to a different station & passed no problem. I did have the stock cats on.

all depends on where you go
i go to two places that doesn't care about visual

Umm think again. When the BOV vents air that the MAF has "metered" the car will run extremely rich for a few seconds because the ECU has no idea where all the "metered air" just went. This will def effect smog. This is why the stock BOV is routed back into the intake.

CA is lame though about smog I agree. If you are on stock turbos and put your stock downpipe on you should pass smog. I passed pretty easy with the stock DP and every other BPU mod.

i know all that about the BOV, i wasn't thinking MAF cars at the time. i forget all about that when i posted :p

even if you recirc, you wouldnt pass with a BOV anyway.

Actually no. FOR A SMOG TEST, a BOV will not effect the smog test because the car is not coming under boost to encounter a rich condition from metered air being blown off by the BOV. However, outside of a smog test, yes a BOV will effect smog when metered air is released to atmo. But the bottom line is, as long as the car is not coming under boost, a BOV will not effect smog. However, technically, it will still cause you to fail visually because BOV's don't have a CARB exemption #.

Actually you are wrong. I speak from factual experience. Instead of assuming things you should do the same.

My wideband o2 provides me with data which PROVES that even under vacuum air escapes to the atomsphere causing a rich condition. This occurs even if there is very little load on the engine.

Why? Can you prove to me that a bov venting the atmosphere does not cause the car to run rich?

Yes you could probably pass smog with the bov venting to the atmosphere. But you can't deny that it does have an effect on smog.

Like the guy said, you won't be "venting" under a ASM test. Why don't you show us your log of a ASM 5015 or 2525 indicating you are either under pressure or "venting" boost pressure. Your statements are completely out of context.

Actually you might have a point there, I didn't consider vacuum. Interesting.

its a combination of who you are/how you look and the person you take the car to. ive never had a smog technician (at test only shops) so much as ask about any of the mods on my car (had 4 smog tests done on the mkiv)...if one complains, buck up and go elsewhere.
