How To Block Off Bov?

[Paulie2256]

isnt it possible to just disconnect the vac line from manifold to BOV... now the BOV wont get the needed vacuum to open.

why must the BOV be removed and the inlets blocked?

you are 100% correct.

step 1. find a small piece of vac line

step 2. disconnect the original vac line at the bov end

step 3. connect the small piece to bov and shove a perfect fitting screw in there

step 4. shove another perfect fitting screw in the original vac line and tie around something so it doesn’t drop into any moving parts.

presto- 2 mins work and can be put back in 2 seconds.

There not designed to put up with the heat in the engine bay. If all else fails I'll get one, but I'd feel more comfortable with a proper stopper which is designed to cope with the heat of the engine bay.

And seeing this picture makes me worry.

They are thick enough to put up with years of abuse under some un-godly-weights that people let themselves get to.

I'm sure they'll survive the life expectancy you want in your engine bay.

The other option is o have some pipe work made up to replace what you have, minus the hole for the BOV.

Just took the BOV off then, I ended up using some chair stoppers, hopefully they'll be fine.

Didn't really notice any difference to the performance at all and only a tiny tiny little flutter lol. Could doing this make your injectors louder, I dunno if its just me being paranoid with the new car or not, but I reckon the injectors click louder now.

Turbosmart end caps are available at autobarn, they offered them to me when I bought block offs. They are metal but at $17 each I declined.

actually there is no need to block the bov... only the line from the manifold.

the bov will not actuate with atmo, needs a vacuum.

I did that at first but bov was leaking boost, psi was half of what it should have been. Using standard bosch bov with plazmaman piping.

after plugging up the vac on the bov it was solved. Although 99% of the time I just leave the bov connected.

After hours and hours of reading trying to get to the bottom of the BOV or not to BOV. . Well after reading many articles I am a little wiser to the BOV debate I hope. The academic literature seems to make assumptions without any solid evidence. But what I have done is read and read, and interestingly enough I came across this link ironically.

This is what I think is the case, and this was further supported by the link below.

1. A BOV is an instrument utilised to allow a vehicle to have greater emissions. that's it

2. A vehicle that has no BOV is actually faster than one that does.

Well fellow enthusiasts, I bite the bullet this morning to actually see what difference a blocked BOV would make. I used coke bottle lids, ground down the outside area so that the rubber pipe would slide over easier. The lids actually fit over the crossover pipe outlets quite nicely. I then used worm clamps and tightened them over the coke bottle tops. So as to have a really good seal that looks stock as a rock. I screwed a very small screw into the the vacuum pipe, and then just pushed the vacuum hose over it. I really wanted to ensure that the whole system was really air tight. I also tightened every clamp in the intake system as I knew that this would place added strain.

Now after some spirited driving on a private road with a friend, the car was raped. Now what I found was that the throttle response was greatly improved, and there was little if any lag on gear changes. So I was hoping to see an improvement, but not to this extent. This leads me to believe that there must of been some sort of leak occurring within the BOV. As I really didn't expect such an improvement. I must also say after looking at the size of the opening of the outlet to the BOV I felt very comfortable doing this, as it not that big.

On the way home we drove past 3 council workers that were digging away (actually working)gave it a bit in second and then backed off (the sound was noticable but not ridiculous). Well straight away, shoves down, and all three gave the thumbs up, and then watched the car until out of sight.

Whenwe got home I thought that I might just check the intercooler to see how hot it was after the punishment. Again to my astonishment the intake side was quite warm but the outlet (air intake) was what I can only describe as "It felt cold", so to all the Monza knockers out there, I'm sorry but for $200 find better, and please don't say that the F6 is just as good, because it isn't. So now I'm hunting autos because I believe that this car might just give them a scare (stock tune). Cheers

I just pulled mine off. Went to bunnings. Bought some door stops. Hose clamped em on...

This post is ridiculous and does not have any merit what so ever.

Gidday Rbjet, yeah I know that's pretty standard practice, but with the cops getting smarter, I wanted the standard look. If I was pulled over about the noise I'd just say it must be broken and I drive em don't fix em. Cheers
