BVSV Broke?

jetjock - Since your gonna be a dick...

I can count. You and the other guy are the only ones who come across as true dumb fucks in this thread. But hey, I gave you the answer anyway and it was correct, regardless of what 3 "mechanics" told you. You can't find it in the manual? Try again. And whose talking about EGR? Moron...

Aye man you got no reason to call me a dumb fuck. Not gonna fight about anything but i didn't say anything about you or anything, don't know why your talkin shit about me. And sorry i got exhaust gasses and gas vapor mixed up in the earlier post, it happens. And again, not talkin shit bout you, just sayin.

jj - Fubar and I may be "dumb fucks" but like I said there were three of us here that didn't know the answer. I guess "dumb fucks" = people who actually ask questions. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=EC&P=6 doesn't say what will happen if you bypass it. Next time I'll be sure to tell the mechanics they don't know what their talking about.


I actually read that page twice lol, but it didn't actually deal with always having it always "open".

Ok so another set of question then
1) prior to cc's how was this problem dealt with?
2) Why is the cc always removed with the egr if it isn't part of it? I guess what I'm getting at is when people want to "clean up their engine bay" they remove the egr just to not have the cc.

Onto the hot side of the engine bay... Liquid gasoline isn't that dangerous, it's the FUMES that are highly flammable.

You're literally playing with fire here...

EDIT: Damn you guys are fast tonight LOL

1) Vented gas caps. Our system was designed for some positive pressure in the fuel tank, you won't have it with a vented gas cap.
2) Exactly, people seem to think that they know better than a company that spent millions on development all in the name of "cleaning up the enginebay."

And im literally dumping the exhaust gasses by my passenger tire :biglaugh:

Anyways, just throwing this out where. What could go BAD if i just plugged the BVSV area and blocked off the 1 nipple on the TB that has to do with the BVSV?

 

[mk3_chris]

SOO pending that I have a "vented gas cap" the cc would only be there to absorb the hydrocarbons? What is the positive pressure for, to help flow the fuel?

You seem to think it's a joke :3d_frown: I don't see engine fires as a joke. Not to mention rubber undercoating catching on fire, hope you have good insurance and they don't notice your negligence...

If you had a vented gas cap the CC would do nothing, the gasses would escape from the cap. Also keep in mind that gasoline is a mixture of many different substances that will evaporate at different rates.

I really don't understand why either one of you think you're going to outthink the engineers...

Man i never said if this would improve anything, or anything like that. I was just asking if any harm is done by doing it. I know the cars are made the way they are for every exact reason, (Been told this too many times on this forum) but im just asking what the BAD would be if i did that since i have it blocked off anyways.

 

[mk3_chris]

I'm actually not trying to out think anyone I have a good bvsv. Just trying to find out why its there/how it works. I'm an engineering student btw so maybe I eventually could make improvements.

That's like two wrongs making a right, does not compute...

That's good, you're actually trying to learn. Much like EGR, the evap system not only cut emissions, but raised efficiency. If it's "ugly" relocate it and make it pretty. Hell, i think the coil packs on top of the engine are ugly, but they're needed :biglaugh:

 

[mk3_chris]

Yup they are deff hideous,

My friend ben just put his jdm 7m in his car and now has no egr or cc or a vented gas cap. How would his gas tank keep the positive pressure and not emplode?

Btw I'm sorry for asking question after question, just one answer leads me to another question.

 

[Poodles]

Probably venting somewhere, and not where he wants it...

 

[mk3_chris]

I can live with that answer, this may sound mean but it'd be cool to see one implode. It would make alot of people believers.

So say if I were to pull my gas cap off and you could hear it suck air in, would that be a sign that the cc isn't working properly? If there is supposed to be positive pressure wouldn't it push air out?

That didn't answer me question lol. Im just gonna do what i feel like doing. We'll see what happens.

 

[Hmong_1G]

If it's there, its there for a reason. It's alot easier to replace the BVSV then trying to disable it's main purpose. If you got valve ticking very loudly, you just don't add thinker oil or additives to quite it. You fix the problem. I got my BVSV new from autozone for a mare $30.00. If nothing happens right away, long term damage is more likely. Save yourselves some time and money later on the line. Keep the negativity in the bag please all.


If you true are going blown out modified, then I can see a purpose in a resolving a solution to bypassing the EVAP system.

And on that note there's NO reason to leave this trainwreck open.
