WolfGod I think you need to upgrade your turbo from your SSAC piece of **** and buy a turbo who's plastic shaft won't snap from 100grams of air.
If you actually think about the opposite torques on the shaft during full boost, then compare that number to the relatively negligible torques upon the throttle shutting, I think you will realise that you and everyone else who think blow off valves do anything is a **** dick and is wasting their time.
Your turbo didn't die from having no blow off valve. No one has any proof of this concept for a reason; It is a myth.</TD></TR></TABLE>
read the ******* post moron, that car is long gone and i dont ******* care what your opinion is, so shove your snobish ******** opinion up your ***, that's what i was told by a mechanic i trust, i've known him all my life
and dont assume my setup either ********, the turbo i had was a small T3 on a carburated setup that died from a combination of compressor surge and fuel spinning through it
this whole post was supposed to be about how to keep a bov from ******* sticking shut, if you dont have any advice for that then STAY THE FU CK OUT OF MY POST AND EAT A DICK *******

Re: (turbosnatch)
omg im a noob on an online forum, how dare i tell people to stay off my thread if they dont wanna help like they should be doing anyway
and i doubt even half of you are my elders either so give it a rest and apply my previous post to yourself as well
my post was made looking for help for a specific problem, you dont wanna help with that then theres no need to post, deal with it

Are you letting your car warm up for 10-15 minutes before driving it? The heat in the engine bay should be enough to "unfreeze your BOV". Did you mean that you let your car warm up for 20 minutes or were driving around for 20 minutes?

If the BOV doesn't work its really not that big of a deal and will not ruin your turbo.... but if you are paranoid you can poor some warm water on the exterior of the BOV, which should only take a couple minutes.

i think he was refering to the heat in the general engine bay area unfreezeing it
warm water is ok but if any gets in it then it'll deffinitly get stuck shut while im at work.. im gonna get some stuff a buddy told me about to help and see if that works, then if nothing else i'll take it off and lube it up really good with WD-40

Re: how common is this? (WolfGod)
use alcohol, it wil unfreeze it an then evaporate. or just take some heat to it... like a small min otrch or something

Re: how common is this? (string)
dude bov's relieve excess pressure on the turbine. If its not a BOV then its a bypass valve but most if not all stock turbo applications have some way of releasing this pressure.
Without relief this pressure will put extra wear and tear on your parts, and more likely than not, lead to them failing sooner
*edit: How does your BOV even freeze shut? does freezing require some liquid to freeze? there should be no liquid near the BOV! I have an HKS SSQV and even in 0 below temps it never freezes shut... maybe its designed diff. then the typeS?

Re: how common is this? (turbotime)
frost build up i'd suppose causeing it to stick, it's been down to -10 here within the last week or so but its starting to warm up a bit

Re: how common is this? (WolfGod)
i think its stuck because of the material its built out of shrinking at different rates due to the low temperatures. its not like a big puddle of water made it under your hood into the BOV. if anything its a little bit of frost which shouldnt hold it shut

On a turbo honda its a good idea to open the hood every mourning and check the basics.
Another idea is to use a heat gun or hair dryer for a couple minutes.

Re: how common is this? (wantboost)
If u cant fix it go around it. Take off the spring in the wastegate so u don't boost! Then when it gets warm again put it back!

Re: how common is this? (dasher)
that really applys to any turbo car.. but in the mornings i normaly am very tired and lazy and dont wanna open the hood, so im tryin to find something that will keep it from freezeing shut
i find something on my car to work on just about every day so i normaly check my fluids and everything else, i just dont like doing more then nessacary in the mornings

Than simply heat your garage overnight with a space heater if your too lazy.
Their arent many other solutions available... if it gets cold, the bov might freeze shut, theirs really no other way around it unless you remove all moisture in the garage.

No the primary purpose of a BOV is for emissions purposes. Most OEm turbo applications use Mass air flow sensors which need recirculating BOV's to make sure the MAF sensor doesn't read the air twice when the air reverses direction.
From a performance standpoint A BOV can help or hurt performance slightly depending on how much boost pressure is used and the way the car is driven. In fact you will never hear a world rally car go pshhh, but rather woof-woof-woof because they get better performance without dumping their boost pressure.
From a reliability standpoint their is no proof that BOV's help at all, infact if you think about it BOV pose a reliability risk because in vacuum they are partially open sucking in air without a filter when using an aftermarket open dump BOV.
You need to understand that shutting closed the throttle and thus cutting off almost all of the air supplied to the engine will in turn dramatically slow the turbine wheel by itself so you do not need to worry about a surge of backpressure causing the compressor wheel to rotate backwards because it never does. The whoof-whoof-whoof sound is merely the noise created by cavitation.
Their are many turbocharged cars which have had long reliable life's without a BOV.

it would cost too much to heat my garage, its drafty and has no insulation (a problem im hopeing to correct this summer)
i just want something that will lubricate the piston well and not allow it to freeze, one person told me of something that might do the trick so im gonna get some while im in town and see how it goes

Re: how common is this? (WolfGod)
how long is the drive? i would think that it should "unfreeze" at some point during it.
btw, i bet ur motor thanks you every time you let it idle for 25 min before driving to work.

In a maf (mass air flow) system the maf sensor reads airflow and adjusts fuel accordingly (of course it looks at other things as well, but this is one input), so if the throttle is closed and reverberated air flows in the opposite direction across the maf sensor again, the sensor will send a signal to the ecu saying that air has passed it and the ecu will add fuel accordingly, thus making your car run richer than it really should be. Hope that helped and didn't confuse the situation even more. I'm not the brightest guy so this info is just from what I have read.
