i know this has probably been covered however i thought i would ask anyway. Just wondering what the law states re the installation of BOV's.

I have been hearing a lot of talk re valves that vent into the atmosphere are illegal. I just had the relevant documents faxed to me and they dont say anything about it. The documents say that you can fit them, as long as they arent to loud, making specific refference to 'whistles'.

There is no mention in the docs that they sent me of how loud they are allowed to be.. something like 91db ive heard?? So i just asked the guy straight out if they were legal, and he said no. So im guessing i have to remove my BOV now, which is a litte bit annoying only for the fact that i only had it fitted 2 weeks ago, and they didnt mention till after they had fitted it that it wasnt exaclty legal :wave:

Can someone clear it up for me? The Information I was sent makes it seem as tho its possible to fit one as long as its not too loud?

Thanks

ok.

any blow off valve is legal. so long as it does not exced 90db in wank noise.

and does not make your car EPA illegal for your year of manafacture.

i was about to get ****ed over for lots of things the other weekend. only got a defect for height. the officer knew what i was on about.

dont let them fine you for BOV. authough, you will get fined if you make BOV noises all around the place.

Just reading waynes post.. I was under the impression that every BOV is illegal.

No matter how much noise it makes... If the noise factor was the cause, the guys that defected me didn't do anything about it except tell me to take it off.. and if they had have got me to rev it, they wouldn't have heard it working anyway because my standard BOV was connected at the same time, so the BLITZ one was doing nothing..

**** I wish our laws were consistent and people knew (police officers/DOT) knew what they were talking about and gave the same story each time.

thanks erin...:) did you cop a fine for the defect or is it just a notice to remove the 'whistle'. there seems to be a lot of debate as to what is and isnt legal.. at this point more ppl seem to think that they are illegal... in saying that i personally hope motox is right... im just trying to find out so that im not voiding my insurance... :D

ring up DOT, ask them if an atmo blow off vale is legal.

they will say so long as its under 90db of noise and it does not polute your car higher then the EPA levels that are set for your year of manafacture.

i got ****ed over the other weekend, they did not defect me for the BOV, i was talking to the cop about it.

ARKAD tell you insurance company that you have a BOV. i listed half of my mods, and had to stop else they wont insure me for just 3rd party. half of the stuff you tell them they have no idear about, eg EBC Boost Controler. and when they ask what does it do, you say, it makes my car run cleaner and better.

insurance is gay. we been ****ed over with a bit fire we had in out buildings, drive propley, learn to drive. dont be stupid, and dont crash, then you wont need to worry about your insurance.

o and i need new tyres :(

Ok, just rang the DOT, and as per Motox's post they are legal. as long as they still comply with EPA standards etc and are not louder than 90db. They gave me the number of a guy who was supposed to be able to test my car for noise. He indicated that for my car the test they would do is a drive by.

The car needs to be at specific revs, in a specific gear and the valve has to blow at the exact time that it passes the meter... he didnt seem too keen test my car and commented that the cops were going overboard with defecting cars, and that the cost would be prohibitive ($500) (i think the DOT had given out his home number a few too many times.to spite that he was very helpful tho.)

He is faxing me the diagram and instructions for testing on monday, but said i would probably have to have it done by someone 'registered' if it were to have any amount of legal standing.

So as far as i can tell, they are legal, as long as EPA and noise requirments are met.

How you can prove it is another matter.

Thanks for your input everyone.

Cheers

Hayden

Thats good news Hayden,

which then brings us back to why do "you or I" have to prove that it is under 90DB and meets EPA Ratings for the year of the car.

Shouldn't the cops have to "prove" that it is over 90DB or that it isn't meeting emission ratings?

If that is not the case then this, in my mind, is what is wrong with the system i.e the police with their immeasurable resources and finances, can just keep giving you defects as often as they want (whether the car is defective or not) and you then have spend your time and money to prove that it is not.

In fact I work next door to some lawyers, I am gunna ask them.

Stayed tuned.

Remember to add the culmulative total of income loss calculated for the rest of your projected working life because of the mental incapcitation you suffered and inability to work you have incurred

Added to that, the loss of income due to the social oucast you've become and downgrading of employability.

Add receipts for to-date rehab (I can forge them for you) and estimated continuation of rehab till you're 65 y/o.

Maybe some community carer benefits? (for me and andrew)

I think you have a case Erin...you and me can take 'em - I'm betting upward of $65m hey? PM and we can set a date to work it all out?

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
